Posts Tagged ‘Common Toadskin Lichen’

Since I recently did a post about lichens that grow on trees I thought I’d do one on lichens that grow on stone. Though there are lichens that can grow on wood or stone most of the ones I know seem to prefer one or the other. In fact the ones I know seem very fussy about where they grow, even down to the species of tree or stone. The lichen in this first photo is not that fussy though, so it will even grow on sidewalks, and that’s how the name sidewalk firedot lichen (Caloplaca feracissima) came about. Though I’ve seen it on concrete once or twice in the past I almost always see it on lime rich stones. It’s a pretty orange color and it can get quite big. This one is as big as a car tire.

Another lichen that can get quite big is the peppered rock shield lichen (Xanthoparmelia conspersa) but this example must have just gotten started because it was quite small and had few apothecia. This lichen likes to grow on stone in full sun and I find a lot of them on stone walls. They’re a good introduction to lichen study because their brown apothecia, where their spores are produced, are large and easy to see without aid.

Lichens are made up of a symbiotic relationship between fungi and algae or cyanobacteria. Technically apothecia are “fungal reproductive structures, in which the fungus reproduces itself through the production of spores” This is not the only way that lichens reproduce, but it is common and the apothecia are often beautiful and well worth watching for. The beautiful brown ones in the photo above belong to the peppered rock shield.

Some lichens are very easy to identify because there aren’t many others that look like them, and the toadskin lichen (Lasallia papulosa) is one of those. Toadskin lichens show color changes when they dry out like many other lichens. When wet it is pliable and pea green and when dry it becomes crisp and ash gray like the above example. Toadskin lichens get their common name from their many “warts.” They attach themselves to stone at a single point that looks like a belly button, and that makes them umbilicate lichens.

This is the very same toadskin lichen as the one in the previous photo. You can easily see the dramatic color change between this day when it was wet and when it was dry in the previous shot.

Rock tripe lichen (Umbilicaria mammulata) is a relative of the toadskin lichen but it doesn’t turn gray when it dries out. Instead it gets brownish and curls up. It is very pliable and rubbery when it’s moist, but once it dries out it becomes crisp like a potato chip. The Umbilicaria part of the scientific name comes from the Latin umbilicus, meaning navel. This is where another common name, navel lichen, comes from and points to how, like the toadskin lichens, they attach themselves to stone with a single attachment point that looks like a navel. It sticks itself to stone by way of this single, navel like attachment point and the rest of the lichen hangs from this central point, much like a rag hanging from a peg.

Here is what rock tripe lichens look like dry. You can see the back of it, which is black and pebble textured. Rock tripe is edible and eating it has saved the lives of people who were lost and starving in the past. Though I imagine they must taste like old rubber, these lichens were a source of emergency food for Native Americans and saved the lives of many an early settler. Even George Washington’s troops are said to have eaten rock tripe to survive the brutal winter at Valley Forge in 1777.

Rock greenshield lichens (Flavoparmelia baltimorensis.) Look like melted candle wax to me. They are very common in this area and are another of those bits of nature that you see so often they no longer register, but when you take the time to look closer you find that they are quite pretty.

If you happen to see a stone that looks like it has sprouted gray hairs you might want to take a closer look, because there’s a good chance you’re seeing a Cladonia lichen.

There are many Cladonia lichens including the well-known pixie cups, but I think these were peg lichens (Cladonia sobolescens.) Peg lichens are also a large group, with split pegs, thatched pegs, powdery pegs, etc., but these seem to fit the description of what the book Lichens of North America calls simply peg lichens. The “peg” is called a podetium and it is topped by brown apothecia.

Here is a closer look at the tiny tan / brown apothecia that sit atop the pegs. These are where the lichen’s spores are produced. They are so small that I wasn’t able to see them but luckily the camera could.

This peg lichen is a squamulose lichen, which means it is scaly, but it is also foliose, or leafy. Squamules are the small leafy, lobed growths that are at the base of the tiny peg shaped podetia. A podetium is an upright secondary thallus in Cladonia lichens. It is a hollow stalk extending from the primary thallus. Podetia can be pointed, club like, cupped, or branched in shape and may or may not contain the ascocarp, which is the fruiting body of the lichen. If the asocarp is bowl shaped it is an apothecium. In this peg lichen the podetia are not branched and the leafy squamules are rounded and grayish green to brown, with white undersides. The quality of these photos isn’t great but the various parts of this lichen are very small. I think they do show enough to make a fairly good identification but if I’m wrong I hope someone will let me know.

Scattered rock posy lichens (Rhizoplaca subdiscrepans) can be quite small and difficult to see without magnification, but it’s worth looking for them because they almost always have their bright orange apothecia showing. They like to grow on stone, especially granite, in full sun. They don’t seem to change their color when they dry out like many other lichens do. I’ve seen this pretty lichen even on mountain tops.

Here is a closer look at those pretty rock posy apothecia. The ones I’ve seen are never shiny. They always have a kind of matte finish.

Common goldspeck lichens (Candelariella vitellina) are uncommonly beautiful. Look for this bright yellow crustose lichen on stone. especially slate. I see it on older gravestones quite often. It shouldn’t come as a great surprise that, at high magnification, the body of the common goldspeck lichen looks like it’s made up of tiny golden specks. The book Lichens of North America describes the body of this lichen as “little cushions of flattened granules.” This lichen is sometimes sterile, with no fruiting bodies present, but this one had a few. Crustose lichens form crusts that tightly adhere to the substrate that they grow on and usually can’t be removed without damaging it.

The golden moonglow lichens (Dimelaena oreina) that I see are usually about an inch across but they can get much bigger. They grow in full sun on granite and don’t seem to change color when they dry out like many other lichens do. The one in the photo was producing spores and that’s something I don’t see this lichen do very often. If you spend much time in cemeteries you have probably seen this pretty lichen, because it seems to like growing on smooth, polished stone, especially granite. It is a crustose lichen, so removing it from a gravestone would be a challenge. When lichens grow on glass the acids in them can actually etch the glass and this is a problem in the big European cathedrals, especially. I would think the same would be true for polished stone.

Another lichen common to stone walls is the sulfur dust lichen (Chrysothrix chlorina.) It’s a very soft, pale yellow and hides under overhangs so it doesn’t get rained on. At least I think that’s why I always find it tucked away like this, but this is odd behavior for a lichen because they usually like a lot of rain and sunshine.

Dog lichens (Peltigera) are good example of lichens that will grow on soil, rotting wood, or stone as this one was. Dog lichens are associated with mossy areas because the mosses help provide the moisture that they need. It is very thin and pliable. It is also a foliose lichen because it is lobed, or leaf like. The upper part of the body (Thallus) is undulating or veined on this example. This lichen is large and easy to see. It is also probably quite old.

Here is another look at the dog lichen. They’re much bigger than most other lichens. I’d guess this one is about the size of a 45 RPM record, if anyone can remember those.

The underside of a dog lichen is often bright white as this one was. They also have small hairs called rhizines which help them cling to whatever they’re growing on.

Smokey eye boulder lichen is a favorite lichen of mine. The blue color seen in the above photo is caused by the way light reflects off a waxy coating on the fruiting bodies, which is very similar to the “bloom” found on plums, blueberries, and grapes. In addition to blue it can also appear black or gray depending on which direction the light happens to be coming from.  The greenish-gold background color is the color of the body (thallus) of this crustose lichen. It’s a very beautiful thing and I hope you’ll take the time to look for it and all of the other beautiful lichens out there.

There is no absolute scale of size in nature, and the small may be as important, or more so than the great. ~Oliver Heaviside

My small climb up along 40 foot falls that I wrote about in my last post inspired me to try something bigger, so last Sunday I decided to climb Hewe’s Hill in Swanzey. A diagnosis of COPD took the wind out of my sails for a while and I wondered if I’d ever climb again, but the medicines they have given me seem to work well and I was able to climb on this day at least as well as I could last year. I started by walking through this frosty meadow.

At about 20 degrees F. it was cool but there was little snow to be seen, so I hoped for a trail without ice. This trail is well traveled and ice is always a problem when constant foot traffic packs down snow and turns it into ice.

Thankfully the trail was ice free, probably because the hemlock boughs overhead have kept a lot of the snow from falling on it. We’ve also had rain and warm temps and I’m sure that helped. I was glad to see it, because I’ve been here when the ice was so bad here I had to leave the trail and go into the woods to make it up the hill.

I think it was about 10 years ago when this hemlock (Tsuga canadensis) was wounded, and I think that because I counted the rings on the scar. I’ve read that hemlock is the only tree that heals scars with growth rings that can be counted.

I also saw a large number of hemlock trees with this yellow crust fungus on them; more than I’ve ever seen. I believe it is the conifer parchment fungus (Stereum sanguinolentum,) which is also called the bleeding parchment because of the red juice they exude when they’re injured. The examples I saw were very dry and thin, almost as if they were part of the bark, and though I tried to scratch one with my fingernail it remained undamaged. Conifer parchment fungus causes brown heart rot, which is a reddish brown discoloration in the wood of conifers. This tree and many others I saw won’t be with us much longer, I’m afraid.

More ice needles than I’ve ever seen in one place grew all along the center of the trail, meaning the soil was saturated. Groundwater at the soil surface is one of the requirements for ice needle growth, and the other is a below freezing temperature right at the very surface of the soil while the soil and groundwater remain thawed. Hydrostatic pressure forces super cooled groundwater out of the soil where it freezes instantly into a needle shape. As more water is forced out of the soil the process is repeated over and over, and each needle grows in length because of more water freezing at its base. Each needle is hexagonal and several will often freeze together into ribbon like bands like those seen here. As they grow they sometimes force the forest floor to heave up, which can be seen happening here.

There are many small holes in the ground made by chipmunks, snakes, and other animals, and these holes often grow hoar frost around their openings. This frost forms when the warm moist breath of the earth meets the cold air at the surface.

The trail gets darker in spots because of overhanging evergreens but on this day it clouded over and made it seem even darker.

I saw some colorful bracket fungi growing in the crack of a tree but I’m not sure what they were. I am sure that they were frozen solid, whatever they were.

I couldn’t account for the beautiful colors of this fallen limb, and I still can’t even guess what would have caused it except weather and age.

A blue jay lost a feather at some point, but on this day the woods were totally silent with no bird songs and no chatter from chipmunks or squirrels. It seemed very strange to have it so quiet.

The steepest part of the trail is near the summit so I knew I was almost there at this point. I was huffing and puffing but no more so than last year or the year before so that was a pleasant surprise. I do know that nature can heal because I’ve experienced it but I don’t know to what extent that healing can happen. I think maybe the only thing that is holding me back is me, but I’m keeping an open mind and believing, and will be very grateful each time I reach a summit.

You don’t realize how much water travels through the soil under our feet until winter. There really is an incredible amount of water moving about in this area, even on our hills.

My daughter and son in law were with me on this climb and all of us tried to move the 40 ton glacial erratic named Tippin Rock, but it wouldn’t budge. I think it was frozen right to the bedrock it sits on. I was a little disappointed because I wanted them to be able to see it move. For new readers, this boulder rocks back and forth just like a baby cradle when you push on it in the right spot, but apparently not in winter.

The big stone has quite a crack in it and someday it might be two stones, which would be too bad. It is a local legend.

The sun had gone, the sky was milk and the views were poor, but since the view isn’t why I climb it was little more than a passing annoyance.

One thing the views from here always show though, are the endless miles of unbroken forest stretching out in all directions. When you stand in such a place you can’t help but wonder, if it was 1760 and you stood here with only an axe head and a gun, what would you have done? It must have been just a bit overwhelming.

I’ve had a great fear of heights since I fell out of a tree and fractured my spine when I was young  so this is as close as I dared to get to the cliff edge. I wanted to show you what a forest looked like from above, but this is the best I could do. You can believe me when I say that this is a drop you would never survive.

There are some huge granite outcrops up here. That tree is a fully grown white pine.

I saw lots of amazing things up to this point but the main reason I chose this hill to climb was so I could visit my friends the toadskin lichens (Lasallia papulosa.) Though I expected them to be very dry from lack of rain or snow a few surprised me by being deep, healthy green. This is their natural color when they’ve had plenty of water and are happy. These lichens attach themselves to stones at a single point that resembles a belly button, and that means they are umbilicate lichens. I always feel as if I’m looking deep into infinity when I look at a toadskin lichen and I may be; there are many who believe that lichens are virtually indestructible and therefore immortal.

Though I doubt toadskin lichens like drying out I kind of like the way they look in their dry, ashen state. They are much like a potato chip when dry and they’ll break almost as easily so I only touch them when they’re green and pliable.

These toadskin lichens were under a good two or three inches of ice and that ice acted like a magnifying glass. Those black spots on the upper one are the lichen’s apothecia where its spores are produced, and without ice magnifying them they’re about the size of the head of a common pin. It’s kind of amazing to see them so big in a photo.

Only in the woods was all at rest for me, my soul became still and full of power. ~Knut Hamsun

As the leaves fall there is much revealed in the forest that was hidden just a short time ago, and lichens are a big part of that revelation. Lichens are all around us but they’re one of those things that are so easy to miss unless we happen to be looking for them. Most people seeing this photo would probably say “Oh yes, I see lichens all over the stones in the stone wall.” But what about the tree? That’s a shagbark hickory tree and they have gray, not white bark. The white is a lichen called, appropriately enough, whitewash lichen (Phlyctis argena.) This lichen is usually found on the bark of hardwood trees and is fairly common. It makes the tree look as if it has been painted white, and that’s where its common name comes from. They can be greenish white, silvery, or bright white.

But you wouldn’t have been wrong in pointing out the lichens on the stone wall because it is covered with them, among them rock greenshield lichens (Flavoparmelia baltimorensis.) This lichen always looks like melted candle wax to me. It is very common in this area and is another of those bits of nature that you see so often they no longer register.

Peppered rock shield lichen (Xanthoparmelia conspersa) likes to grow on stone in full sun and I find a lot of them on stone walls like the one pictured in that first photo. They’re a good introduction to lichen study because their brown apothecia, where their spores are produced, are large and easy to see without aid. Lichens are made up of a symbiotic relationship between fungi and algae or cyanobacteria. Technically apothecia are “fungal reproductive structures, in which the fungus reproduces itself through the production of spores” This is not the only way that lichens reproduce, but it is common and the apothecia are often beautiful and well worth watching for.

Another lichen common to stone walls is the sulfur dust lichen (Chrysothrix chlorina.) It’s very yellow and hides under overhangs so it doesn’t get rained on. At least I think that’s why I always find it tucked away like this, but this is odd behavior for a lichen because they usually like a lot of rain and sunshine.

Sulfur dust lichens are kind of granular in texture. If you’re lucky you can sometimes find them with fruiting bodies (apothecia) but more often than not I see them when they aren’t producing spores, like this example.

If you spend time walking along old stone walls eventually you’ll see a stone with a splash of bright orange on it and it will probably be the sidewalk firedot lichen (Caloplaca feracissima,) so called because it is a lime lover and grows on concrete sidewalks, which have lime in them. When you see it in a stone wall it’s a fair bet that the stone it grows on has limestone in it too. This stone looks like granite to me but it is almost completely covered by it.

A closer look at this example of the sidewalk firedot lichen showed it was made up of mostly irregularly shaped fruiting bodies, so it was making plenty of spores. It was raining just a short while before I took this photo so it was also still wet. Lichens are at their best when they are wet because that’s when they’ll show their true colors and size, so that’s when serious lichen hunters look for them. A misty or drizzly day is perfect.

I know of an old stump that has more British soldier lichens (Cladonia cristatella) growing on it than I’ve ever seen in one place. Old rotted logs and stumps are the perfect places to find them and their bright red color makes them relatively easy to spot.

Even I can see this shade of red, and I’m colorblind.

If you see a tree with growths like this on it you really should take a closer look, because there are some amazing things going on here.

One of the things going on in the tree in the previous photo is what is happening on this star rosette lichen (Physcia stellaris.) Its apothecia are a good example of how colors can change, even on the same lichen. This lichen has dark brown apothecia that are often pruinose. Pruinose refers to the white, waxy, powdery coating on the apothecia. You’ve no doubt seen examples of this waxy “bloom” on blueberries and plums. I’ve noticed by watching lichens that have pruinose apothecia that the coating can reflect light in different ways, sometimes appearing gray and at other times more blue, and sometimes even black. The apothecia on this lichen show a range of colors, from brown to light blue. The way the sunlight strikes it has a lot to do with its colors, so sometimes you have to visit a lichen more than once to understand it.

Common goldspeck lichens (Candelariella vitellina) are uncommonly beautiful. Look for this bright yellow crustose lichen on stone, in this case slate. It’s a very artistic lichen and I like the patterns that it makes. I see it on gravestones quite often. It shouldn’t come as a great surprise that, at high magnification, the body of the common goldspeck lichen looks like it’s made up of tiny golden specks. The book Lichens of North America describes the body of this lichen as “little cushions of flattened granules.” This lichen is sometimes sterile, with no fruiting bodies present, as this one appeared to be. Crustose lichens form crusts that tightly adhere to the substrate that they grow on and usually can’t be removed without damaging it.

The golden moonglow lichens (Dimelaena oreina) that I see are usually about an inch across but they can get much bigger. They grow in full sun on granite and don’t seem to change color when they dry out like many other lichens do. The bigger one in the photo was producing spores and that’s something I don’t see this lichen do very often. If you spend much time in cemeteries you have probably seen this pretty lichen, because it seems to like growing on smooth, polished stone, especially granite. It is a another crustose lichen, so removing it from a gravestone would be a challenge. When lichens grow on glass the acids in them can actually etch the glass and this is a problem in the big European cathedrals, especially. I would think the same would be true for polished stone.

Bright yellow-orange poplar sunburst (Xanthomendoza hasseana) is a beautiful lichen with its large disc shaped, sucker like fruiting bodies (apothecia) which are almost always showing. It’s found on tree bark and provides a lot of color in winter when there are no flowers to see. The example shown here was about as big as a penny, or about .75 inches across.

Another sunburst lichen, the elegant sunburst (Xanthoria elegans) was exposed to ultraviolet radiation, cosmic radiation, and the vacuum of space for one and a half years and when it was brought back to earth it grew on as if nothing had happened. Many believe that lichens are virtually indestructible and are therefore as close to immortal as any earth based life form can be.

Pink earth lichen (Dibaeis baeomyces) closely resembles bubblegum lichen (Icmadophila ericetorum.) One of the differences between the two is the length of the stalks that the plump pink apothecia sit on. They are longer on bubblegum lichens than they are on pink earth lichens. Both are very beautiful things that are rarely seen in this area. The whitish or grayish thallus, or body of the lichen, grows on soil; usually on dry acidic soil near blueberry and sweet fern plants. It can sometimes have a bluish cast as well.

Here’s a closer look at the apothecia on the pink earth lichen. You can also see the stalks that support them.

Scattered rock posy lichens (Rhizoplaca subdiscrepans) can be quite small and difficult to see without magnification, but it’s worth looking for them because they almost always have their bright orange apothecia showing. They like to grow on stone, especially granite, in full sun. They don’t seem to change their color when they dry out like many other lichens do. I’ve seen this pretty lichen even on mountain tops.

Some lichens are very easy to identify because there aren’t many others that look like them, and the toadskin lichen is one of those. Toadskin lichens show color changes like many other lichens. When wet it is pliable and pea green and when dry it becomes crisp and ash gray. This example hadn’t completely dried out but it was on its way, even though it had rained that morning. Toadskin lichens get their common name from their many “warts.” They attach themselves to stone at a single point that looks like a belly button, and that makes them an umbilicate lichen. This toadskin is very special, because it is the only one I’ve ever seen that wasn’t on a hill or mountain top. It grows on a boulder at the very water’s edge of a lake and I’m very happy that I found it now that hill climbing is getting more difficult. Now at least I’ll still be able to see these beautiful little things without having to struggle to reach them, if it comes to that.

Smokey eye boulder lichens (Porpidia albocaerulescens) are one of the most beautiful in my opinion, but their beauty is fleeting and it depends on how the light happens to fall on them. If you find one it might not look like this one at all. The pretty golden brown body (thallus) of the lichen is peppered with blue apothecia which again, are colored by the light. Take a look at the next photo to see what a simple change in light can do.

This is the exact same lichen we saw in the previous photo; all that is different is the light, and that’s why if you’re at all interested in lichens you really should visit them at different times of year, as I said when we looked at the star rosette lichen. The previous photo was taken when sunlight was falling on it, and this shot was taken when the lichen was in shade. Not only light but dryness can affect the color of many lichens, so make a note of where you find them and then go back when the weather has changed. I think you’ll be amazed by how much they can change, and also by how beautiful they can be.

There is a low mist in the woods—it is a good day to study lichens. ~Henry David Thoreau

I’ve been itching to climb a hill for a while now but the weather has kept me away. It has warmed up enough to rain several times this winter and then it has gotten cold immediately after and ice has built up just about everywhere. Finally for the last 3 or 4 days of last week it warmed up and didn’t rain so I thought I’d climb Hewe’s Hill in Swanzey last Saturday. It was relatively warm at about 36 degrees F. and the trail of footprints through the pasture showed that I wasn’t the only one with an itch to climb.

As I thought there might be there was ice on the trail, but at the start it was only in spots and I had my Yaktrax on, so I didn’t worry about it.

Other parts of the trail were snow covered. I stopped to admire a beech tree that was caught in a ray of sunshine.

I saw a curious stone with moss growing in concentric rings around it. I’m guessing depressions in the stone gather water and stay wet longer than the rest of the stone, and the moss is attracted to the moisture. The same happens vertically when the natural channels in tree bark become small streams when it rains. Mosses grow along these vertical streams, and so do lichens and algae.

I almost turned back when I saw this much ice but after scratching my head for a moment or two I decided I’d climb in the woods beside the trail for a while, and once there was no more ice I’d return to the trail.

Just so all of you who wear Yaktrax know; you can slip and fall with them on. I almost went down in this spot.

The forest didn’t look too bad to walk through. It was snowless and open in many areas but here is another warning about Yaktrax: sticks can get in between the Yaktrax and the sole of your boots and get caught there, so when you try to move forward your trapped foot stays where it is and you go down face first. The solution is to walk slowly, which I do ayway. Walking slowly is the only way to see those interesting “hidden” things in a forest. Walk at a toddler’s pace and you’ll see some amazing things. Hurry along to the end of the trail and you’ll see nothing.

I saw quite a few interesting things, including this cocoon attached to a beech bud. I’m calling it a cocoon instead of a gall because it was attached to the bud with silk. I don’t have any idea what insect made it or why it would be so exposed, out at the tip of a branch on a terminal bud like it was. It seems like a poor choice to me, but I could be very wrong. Maybe the sunshine in that spot keeps it warm.

Some things I saw were’t so quite so interesting, like this fallen hemlock I had to find my way around.

I couldn’t find the stump that the hemlock had broken off from until I looked up. It was actually the top of a huge tree that had broken off way up there. I was glad there was no wind on this day.

Before the hemlock lost its top it made sure that many children would follow, as this grove of young ones beside it revealed. It was as hard to get through it as it was to get over the broken tree top.

And then the ice came up off the trail and into the woods and I began to question my judgement in doing this. I almost threw in the towel and called it a day in this spot but instead I moved further into the woods for a while.

Finally, after climbing nearly the entire trail in the woods, just before the summit the ice was gone and I walked comfortably on frozen soil again. This is the steepest part of the trail so I was very happy to see it ice free. The reason for so much ice on is because the trail never sees direct sunshine and when it rains all the water runs down it as if it was a stream. Layer by layer the ice builds in thickness each time it rains and the only thing that will get rid of it is a few days of 50 degrees or more. We reached 61 degrees Tuesday and are supposed to reach 70 degrees today, so all of the ice you’ve seen here is probably gone now.

With a nod and a tip of my hat I passed the 40 ton glacial erratic called Tippin Rock that lives on the granite slab that is the summit. It’s called that because you can indeed tip the behemoth and watch it rock slowly back and forth like a cradle. I’ve written about it several times so if you’d like to know more about it, just type “Tippin Rock” in the search box there on the upper right of this page.

The trail passes Tippin Rock and leads to the granite overlook where the views are seen. I saw that there was a big old maple tree slowly falling over. When it finally makes it all the way down it will block the trail. There were many fallen trees here on this day. I just went aroud this one.

There were ice falls on the ledges. This ice was as clear as window glass and there was a lot of dripping going on. You don’t realize just how much groundwater is in a place until you visit it in winter. Though it seems dry in summer there is seeping groundwater everywhere in this forest.

The view on this day was hardly worth taking a photo of because the sun always shines directly at you in the afternoon in this spot, but I did want you to see what you’re faced with when you look out at it: a vast forest, too big to even comprehend. Though it couldn’t really be called unbroken it seems like it is, and waves of lonesomeness can ripple through you when you see it. It’s as if you’re the only person within many miles and that must have been a very sobering thought for the people who settled this land, because except for the Natives they really were the only ones here. They had nothing and no one to rely one except themselves and what they carried, so looking out over something like this must have made them wonder exactly what they had gotten themselves into.

But as far as this day went I knew that as soon as I climbed back down I wouldn’t be the only one anymore, and since I believe that solitude is good for the soul I love to spend time in high places like this where there is nothing except you, the land, and the breezes. Any troubles you may have in life look much smaller from up here, and you can be emptied of them while you relax into the silence.

It seems like it has been a very long time since I last visited my little friends the toadskin lichens (Lasallia papulosa) so I was happy to sit with them for a while. This one was partially covered by ice but it had water dripping on it so it was very happy, and I know that because of its color. When everything is going right a toadskin lichen will be pea green and pliable, like an ear lobe. The dark spots on the body of the lichen are its disc shaped apothecia, where its spores are produced. A fruiting lichen is a happy lichen, because when you’re a lichen it’s always all about making more lichens.

When toadskin lichens dry out they get crisp like potato chips and turn an ashy gray like this one. They’re not very happy at this stage but if nothing else lichens are patient beings, and they will just wait until it rains or snows so they can become pea green and rubbery again. Toadskin lichens are umbilicate lichens, which means they attach to the stone at a single point, and this one displayed what I call its belly button beautifully; it is the sun at the center of its solar system. Though they aren’t at their happiest I think these little lichens are at their most beautiful when they’re dry like this one, and I’ve lost myself inside that beauty many times.

I went a little further along the trail and visited the ledges where the rock climbers climb. I thought I might find some big ice here but instead I found a small pile of slush at the base of the ledge, so that means the sun is warming this huge mass of stone. To give you an idea of how big it is; that pine tree is probably about 75-100 years old. Someday I’m going to go up there and see what I can see.

But for now it was time to head back down Hewe’s Hill and, though climbing down is almost always harder than climbing up, on this day it was doubly hard and I think I’ll wait until it warms up before I climb again. But I made it up and down without falling and I saw some amazing things, so it was great day to be in the woods. I went home happy on rubbery legs.

Unfortunately there are people who think that once the leaves have fallen there is nothing left to see outside until spring, but they couldn’t be more wrong. Lichens for instance, are there year round and unless you live in a place with poor air quality they are everywhere; on trees, on stones, on the ground, and even on buildings, roofs, windows, and sidewalks. They are like small jewels that have been sprinkled throughout nature and one of my favorites is the smoky eye boulder lichen (Porpidia albocaerulescens) shown above. The blue dots are called apothecia and are where its spores are produced. They are blue because of the way the light reflects off the thin wax coating that they are covered by. In this case the body of the lichen, called the thallus, is a brownish gold color. The thallus can also be gray and the apothecia gray to black. One of the things that can make lichen identification difficult is the ability of some lichens to change color in different light, and this is one that does. It can look very different just a few feet away.

The apothecia on this star rosette lichen (Physcia stellaris), is a good example of how colors can change, even on the same lichen. This lichen has dark brown apothecia that are often pruinose. Pruinose refers to the white, waxy, powdery coating like that found on the smoky eye boulder lichen in the previous photo. You’ve no doubt seen examples of this waxy “bloom” on blueberries and plums. I’ve noticed by watching lichens that have pruinose apothecia that the coating can reflect light in different ways, sometimes appearing gray and at other times more blue, and sometimes even black. The apothecia on this lichen show a range of colors, from brown to light blue. The way the sunlight strikes it has a lot to do with its colors.

I used my magic gravity defying penny so we could get an even better idea of the scale of some of these lichens. For those of you not familiar with the size of a penny, they are 3/4 of an inch (19.05mm) in diameter. The powdery sunburst lichen just above it is almost the same size. The lichens below, right and left of the penny are star rosette lichens like the one we just saw in the previous photo. That penny could use a good cleaning.

This is the powdery sunburst lichen (Xanthomendoza ulophyllodes) we saw above the dirty penny in the previous photo. This foliose lichen is easy to see even when it’s small, because of its bright orange yellow color. This lichen really likes moisture and is often found growing near channels that carry water on stone or bark. A foliose lichen has a lobed, leafy look.

British soldier lichens (Cladonia cristatella) like to grow on damp wood like rotted stumps and logs, but I’ve found them on buildings, fence posts, and built up forest litter on boulders. At this time of year I don’t pass too many mossy old tree stumps without having a glance for British soldiers. Their bright red apothecia make them easy to see, even if you’re colorblind.

Pink earth lichen (Dibaeis baeomyces) closely resembles bubblegum lichen (Icmadophila ericetorum.) One of the differences between the two is the length of the stalks that the plump pink apothecia sit on. They are longer on bubblegum lichens than they are on pink earth lichens. Both are very beautiful things that are rarely seen in this area. The whitish thallus, or body of the lichen, grows on soil; usually on dry acidic soil near blueberry and sweet fern plants. It can sometimes have a bluish cast as well.

I find pebbled pixie cup lichens ((Cladonia pyxidata)) growing on soil or rotting stumps and logs, and occasionally on stone. Pixie cups look like tiny golf tees or trumpets. They are squamulose lichens, and the golf tee shapes arise from leafy growths called squamules. A squamule is a lobe of the body of the lichen (thallus,) and  squamulose lichens have small, leafy lobes.

Though pixie cup lichens are squamulose they have fruticose fruiting structures called podetia. The parts that look like tiny golf tees are called podetia. “Podetia” describes a stalk like growth which bears the apothecia, or fruiting bodies. This example shows some almost microscopic dots around the rim, which are its apothecia. Finally, frucitose means a lichen has a bushy, vertical growth. Since this example has squamules even growing inside the tiny cups it must be a pebbled pixie cup lichen.

A single raindrop was caught in the cup of this pixie cup and it illustrates how the cups are meant to do exactly this; they are splash cups and when a raindrop lands in them the water splashes the spores out and away from the lichen to hopefully colonize new ground. Pixie Cups and other Cladonia species like reindeer lichen contain didymic acid, and they were once used by herbalists to treat tuberculosis.

Dog lichens will grow on soil, rotting wood, or stone as this one was. The example pictured is I believe, a membranous dog lichen (Peltigera membranacea.) Dog lichens are associated with mossy areas because the mosses provide the moisture that they need. It is known as membranous lichen because it is thin and pliable. It is also a foliose lichen because it is lobed, or leaf like. The upper part of the body (Thallus) is undulating or veined. This lichen is large and easy to see. It is also probably quite old.

One theory behind the name “dog lichen” says that the name refers to the large, lobed body of the lichen looking like dog ears. It sounds plausible, but so do the other three theories I’ve heard. One says the fang like rhizines look like dog’s teeth, another says the entire lichen body looks like a dog, and yet another says that the apothecia, or fruiting bodies, look like dog ears. I’ve never seen this one produce fruiting bodies so I can’t verify that last one and it doesn’t really look like a dog to me, so I can’t verify the second one either.

What sounds most plausible to me about the origin of the name “dog lichen” are the white “roots” on the white underside of the lichen body. They are fang like and called rhizines. On some lichens they can be quite bushy, but on Peltigera membranacea they are narrow and thin. They are one of the identifying characteristics of this lichen along with its thin, flexible, undulating thallus.

Common goldspeck lichens (Candelariella vitellina) are uncommonly beautiful. Look for this bright yellow crustose lichen on stone. It’s a very artistic lichen and I like the patterns that it makes. I see it on gravestones quite often.

It shouldn’t come as a great surprise that, at high magnification, the body of the common goldspeck lichen looks like it’s made up of tiny golden specks. The book Lichens of North America describe the body of this lichen as “little cushions of flattened granules.” This lichen is sometimes sterile, with no fruiting bodies present, as this one appeared to be.

Scattered rock posy lichen (Rhizoplaca subdiscrepans) is both beautiful and unusual with its brain like body and orange fruiting bodies. This one was growing on stone in full sun. There was a time when I knew of only one example but now I see them everywhere, even on mountain tops. This example was about as big as a penny.

If you spend time walking along old stone walls eventually you’ll see a stone with a splash of bright orange on it and it will probably be the sidewalk firedot lichen (Caloplaca feracissima,) so called because it is a lime lover and grows on concrete sidewalks, which have lime in them. When you see it in a stone wall it’s a fair bet that the stone it grows on has limestone in it too. This stone is almost completely covered by it.

A closer look at this example of the sidewalk firedot lichen showed it was made up of mostly irregularly shaped fruiting bodies, so it was making plenty of spores. It was raining at the time so it was also very wet. Lichens are at their best when they are wet because that’s when they’ll show their true colors and size, so that’s when serious lichen hunters look for them. A misty or drizzly day is perfect.

One thing you learn quickly when you decide to study lichens is that your pockets will be as full of unknowns as they are knowns, and this lichen shows why. You’ll see why in the next photo, so try to remember how it looks here.

Not only do lichens change color but shape as well. It’s hard to believe that this is the same kind of lichen that we saw in the previous photo but it is, and it is the apothecia in full “bloom” that makes it look so different from photo to photo. This is why it has taken me as long as three years to identify some lichens. I’m not completely comfortable with my identification of this one but I think it might be the brown eyed rim lichen (Lecanora epibyron.) Brown eyed rim lichen is described as a “white to very pale brown crustose lichen with many red-brown apothecia with a white margin.” It seems to fit, but if you know this lichen and know that my identification is wrong I hope you’ll let me know.  I found it growing on ash tree bark.

As its name implies maple dust lichen (Lecanora thysanophora) grows on the bark of maple trees, but I’ve also seen it on beech, oak, and basswood. One of the easiest ways to identify this lichen is to look for the white fringe around its perimeter. This is one of those lichens that I never saw until I stumbled across it one day, and now I see it everywhere. This beautiful example was about 3/4 of an inch in diameter, or about the size of a penny.

Some lichens are very easy to identify because there aren’t many others that look like them, and the toadskin lichen is one of those. Toadskin lichens are another one that shows color changes. When wet it is pliable and pea green and when dry it becomes crisp and ash gray. This example hadn’t completely dried out but it was well on its way. Toadskin lichens get their common name from their many “warts.” They attach themselves to stone at a single point that looks like a belly button, and that makes them an umbilicate lichen. This toadskin is very special, because it is the only one I’ve ever seen that wasn’t on a hill or mountain top. It grows on a boulder at the very water’s edge of a lake and now I know, if the day comes when I can no longer climb, I’ll still be able to see these beautiful little things.

I hope you’ve enjoyed seeing a few of the lichens I know and I hope you’ll look for them in your area. Just look closely anywhere you happen to be; they’ll be there too.

Oh what a strange nature is knowledge! It clings to the mind when it has once seized on it like a lichen on a rock. ~Mary Shelly

Last weekend I remembered that I hadn’t climbed any hills in a while so I chose Hewe’s Hill in Swanzey. The trail starts in a meadow / hayfield and I was surprised to see a path starting to wear into the grass. I suppose it must be becoming a popular climb even though I rarely meet anyone here.

There was a nice display of big leaf asters (Eurybia macrophylla) and gray goldenrod (Solidago nemoralis) along the edge of the field. The big, hand sized, heart shaped leaves helped me identify the asters.

The trail starts out narrow and level but before long it widens and angles uphill.

A ray of sunshine had found a colony of shining clubmoss (Lycopodium lucidulum) and made it shine even more. This clubmoss is unusual and easy to identify because it is unbranched and grows fairly erect.

Cockscomb or crested coral (Clavulina cristata) grew on the side of the trail. Crested corals have branches that end in sharp tips and these tips will often turn brown, but these examples were still nice and white. It had rained all day the day before so it might have been very fresh. I’m not sure what the tiny yellow fungus in the background was.

The names pinwheel and horsehair mushroom are interchangeable and go by the scientific name of Marasmius rotula. They grow on decaying leaves and decaying wood and can appear overnight after a good rain. They are very small and rarely grow larger in diameter than a pea. This one grew on last year’s leaves and was easily the largest I’ve ever seen with a diameter equal to that of an aspirin.

Another record mushroom in my book was this hemlock varnish shelf fungus (Ganoderma tsugae.) It was larger than a dinner plate and I’d guess quite old. Its common name comes from its shiny cap which usually looks like it has been varnished, but this example was very dirty. This mushroom is considered the most important of all the herbs and substances used in Chinese Herbal Medicine, including ginseng. In China it is called the Reishi mushroom and scientists around the world are researching its anti-cancer potential.

The trail goes gently uphill until we near the summit where the grade is steep. It’s very dark through this section of forest because of the overspreading evergreen branches of pines and hemlocks.

If you look closely at the tree to the left of the trail in the previous photo you can see that it is full of woodpecker holes. This photo shows how the wind carried mushroom spores into one of those holes and they grew there, fruiting on this day or the day before. This is how fungi infect and almost always kill the trees they grow on. All it takes is a small wound, and that’s why wounds on expensive ornamental or fruit trees should be quickly treated.

When trees die they eventually fall and I saw several down across the trail. This hemlock was the largest. Note all the tree roots on the trail where the soil has washed and worn away. They can be very slippery after a rain and I slipped on them a few times on my way down the hill.

Hammered shield lichen (Parmelia sulcata) and crowded parchment fungi (Stereum complicatum) battled for space on a fallen limb. There was plenty of room for both to the right and left but crowded parchment fungi often covers entire logs, so it wants all the space.

Yellow patches (Amanita flavoconia) gets its common name from the yellow bits of the universal veil on its orange cap. The universal veil is made of tissue and completely covers the young mushroom. As the mushroom grows it eventually breaks through the membranous veil and pieces of it are left behind on the cap. Rain can wash them off so I was surprised that they have stayed in place on this example. This mushroom is in the amanita family and is considered toxic. The amanita family contains some mushrooms that can kill if eaten, so I never eat any mushroom that I’m not 110% sure is safe. In truth I’m not crazy about mushrooms anyhow so their toxicity is a non-issue for me.

Indian cucumber root (Medeola virginiana) was showing its fall colors. This plant has small black berries but this example didn’t have any. Little is known about what animals eat the berries but it is said that the Native American Iroquois tribe used the crushed dried berries and leaves to treat convulsions in infants. Native Americans also ate the roots of the plant, which taste and smell like a cucumber. I accidentally scared a turkey away and I wondered if it was that bird eating all the berries. I also saw plenty of blueberry bushes but not a single one had a berry.

This fungus grew right on the ground and looked like it was pretending to be a pizza. I haven’t been able to identify it.

I didn’t expect the views to be very good due to the previous day’s heavy rain, so I wasn’t disappointed when they weren’t. It was very hazy but you can still see the trees; countless thousands of them. I didn’t see much leaf color yet though some seemed to be lightening up to a yellow green.

Out of several shots of the views I took this is probably the best as far as lack of haze.

As I stood scanning the trees for signs of fall color a large shadow crossed over me and when I looked up I saw a flock of what I think were turkey vultures circling silently above me. They looked to be huge, and there had to have been 7 or 8 of them. Big birds flying across the skies; throwing shadows on our eyes. These words from Neil Young’s song Helpless played in my mind as I watched them soar.

These aren’t very good photos but my getting-photos-of-birds-in-flight skills are just about nonexistent. What struck me most about these birds other than their large size was how absolutely silent they were. They never made a sound the whole time I watched them; there wasn’t even the sound of wind in their feathers even though they flew so close once or twice it seemed like I could have reached out and touched them.

Because of the previous day’s rain many of the little toadskin lichens (Lasallia papulosa) that live up here were their natural green color and plump with plenty of moisture. When wet the greenish color of the algae that is present in the lichen comes through on the surface. The tiny black specks in its lower left corner are its disc shaped fruiting bodies, called apothecia, where its spores are busily being produced so a new generation of toadskins can get their start.

When wet toadskin lichens are rubbery and pliable and feel much like your ear lobe but when they dry out they are much like a potato chip, and will crack just as easily.  Like many lichens they also change color when they dry out, like the dry example in the above photo shows. The warts on its surface are called pustules and on the back of the lichen there is a corresponding pit for every pustule. Each lichen is attached to the rock at a single point that looks much like a belly button, so this is an umbilicate lichen. This example’s belly button is the bright spot that looks like a sun in a solar system.

I’ve written several posts about Tippin Rock, which is the 40 ton glacial erratic that lives up here, so I was going to just pass it by without taking a photo, but then I saw something I hadn’t seen before. At first I thought I had come upon one of those benevolent forest sprites whose job is guiding creatures who pass through the woods and protecting the forest, but instead it was Gus. “Are you tipping that rock?” I asked, and Gus giggled and said no, it was his father making it tip. Gus is a happy little guy who was overcome by bursts of great joy each time his father made Tippin Rock tip. It’s truly amazing to see 40 tons of granite rock gently back and forth like a baby cradle and Gus was having a ball riding the huge stone but truth be told, his dad was looking a little winded. From what I gathered Gus and his dad and their dog Annie had come up here specifically to tip the rock, and tip it did, again and again and again. Once I thought it might actually tip off its natural keel and never move again but Gus rode it out and everything was fine.

I don’t get many chances to show a person’s size in relation to the big boulder so I was grateful when Gus’s father graciously said that I could take a few photos. Gus is a very bright, joy filled five year old who is as cute as a button. He told me that he likes school and loves his teacher very much, and I told him that I’d bet that his teacher loved him right back. Gus also told me that he and his family were having a dinner party the following evening and said that I should come so he could show me around, but I left the family to their fun and headed off down the hill.

Anyone who reads this blog regularly knows how I harp about people getting into the woods so it was a real pleasure meeting Gus and his dad and their dog Annie up there; easily the high point of my entire weekend. I hope Gus grows up to be a great lover of nature; he’s certainly off to a great start.

We had a day with blue skies, puffy white clouds, and low heat and humidity so I thought I’d take advantage of such a fine day by climbing Mount Caesar in Swanzey. The mountain it is said, is named after a freed slave named Caesar Freeman and he is supposed to be buried somewhere on it, but nobody really seems to be able to verify any of the tale. One thing about the mountain is certain; Native Americans used it for a lookout and in the mid-1700s they burned Swanzey to the ground, house by house and mill by mill. The climb to the top starts on a path of solid granite bedrock, as is seen in the photo.

One of my favorite things to see on Mount Caesar is this river of reindeer lichen. Since there are no reindeer or other animals to eat the lichens they thrive here. But they are fragile and should never be walked on.  Reindeer lichen is very slow growing at about an eighth to three eighths of an inch per year and if overgrazed or dug up, it can take decades for drifts like the one pictured to reappear. The Native American Ojibwa tribe was known to bathe newborns in water in which reindeer lichens had been boiled.

Just before you enter the forest there is a meadow teeming with wildflowers. On this day most of what was blooming were pale spike lobelias (Lobelia spicata,) which get their common name from the small, pale blue to almost white flowers. Every now and then you can find a plant with deeper blue flowers, but most are pale.

Sometimes if you look carefully you can find dark blue pale spike lobelias, as this one was. These flowers are small; hardly bigger than a standard aspirin. Native Americans had many medicinal uses for lobelia and one of them was as a treatment for asthma, but it has to be used with great care because too much of it can kill.

Stone walls will follow you almost all the way to the summit of Mount Caesar and remind hikers that this land was once completely cleared of trees. I’d guess that sheep once grazed on the mountain’s flanks, as was true of most of the hills in the area. The walls most likely date from the late 1700s and early 1800s. Not old enough to be covered by moss yet but there certainly are plenty of lichens on them. The yellow ones seen in the photo are sulfur dust lichens (Chrysothrix chlorina). This lichen doesn’t like to be rained on so it is usually found hiding under some type of overhang.

I saw many mushrooms on this climb, among them yellow chanterelles (Cantharellus cibarius.) I’m not a real mushroom aficionado but I know this edible mushroom is considered choice. I don’t see many but when I do it’s usually about this time of year or a little earlier, and I always see them growing right alongside trails. It is believed by some that the compacted earth of the trail or road may cause the chanterelle mycelium to react by fruiting.

Another mushroom I saw in great abundance was yellow patches (Amanita flavoconia,) and it is not a choice edible fungus, in fact it is poisonous and should never be eaten. This mushroom is identified by the chrome yellow “warts” on the cap, which are easily brushed off. It prefers growing in hemlock forests, so it is right at home here. It is said to be one of the most common and widespread species of Amanita in eastern North America. It faintly resembles yellow fly agaric (Amanita muscaria v. formosa) but that mushroom has white warts on its cap.

I’ve seen people go up to the summit and then back down again in the time it took me to reach the half way point but this isn’t a race and I dawdle and wander, looking at this and that all the way up and down the mountain. A 45 minute climb with me can easily take half a day, and that’s why I almost always hike alone. To see the kinds of things that I see you absolutely must walk slowly and from what I’ve seen most people simply aren’t able to do it. Unfortunately most people I’ve seen and spoken with in places like this seem to feel that the end of the trail is far more important than what can be seen along it and race through it. If only they knew that they were missing all of the best that nature has to offer.

Eastern teaberry (Gaultheria procumbens,) bloomed all along the trail. This native wintergreen is in the same family as the blueberry and its flowers show that. Teaberry is also known as checkerberry or American wintergreen and by fall its flowers will have turned into small red berries that taste minty, like Teaberry chewing gum. Many animals, from foxes to chipmunks, and birds including grouse and pheasant rely on the berries to help them get through the winter. Wintergreen oil has been used medicinally for centuries, and the leaves make an excellent, soothing tea. The plant’s fragrance is unmistakable and its oil is used in toothpaste, mouthwash, pain relievers, and many other products.

Before too long the approach to the summit appears as granite bedrock, and that’s when you realize that this mountain is just a huge piece of solid granite with a few inches of soil covering it. I’ve seen several trees that have blown over and their roots were very shallow. They have to be because they can’t penetrate the granite.

I like a few clouds in the sky to give it some interest. A year or two ago we had an entire summer of blue skies with not a cloud to be seen, and it was quite boring if you wanted landscape photos. I like the way the shadows of the clouds pass over the land. It’s something I’ve watched and enjoyed since I was a boy.

The view was hazy in some directions but I usually spend time marveling at how vast this forest really is, so I don’t mind a little haze.

Mount Monadnock could be seen through the haze off to the east but it wasn’t a day for mountain portraits.

You need to watch where you step when you’re taking photos of the mountain because you have to get close to the edge of the cliff if you want the best shot. This is one time when it isn’t wise to step outside of yourself and become totally absorbed by what you see before you. It’s a long way down and for someone who doesn’t like heights it’s a stomach knotter, and I tread very mindfully up here.

I was surprised to see so many old friends up here, like this bristly sarsaparilla. It made me wonder if it has just moved in or if I have been negligent and ignored it on previous climbs. It obviously likes it up here; it was blooming well. It normally grows in dry, sandy soil at road edges and waste areas. Its stems are covered in short, sharp, bristly hairs and that’s where its common name comes from. Technically, though it looks like a perennial plant, it is considered a shrub because the lower part of its stem is woody and persists throughout winter.

Each tiny bristly sarsaparilla flower will become a round black berry if the pollinators do their job and it looked like they were hard at it. I’m not sure what this insect’s name is but it was very small. The entire flower head of the plant in the previous photo is barely bigger than a ping pong ball.

Blue toadflax (Nuttallanthus canadensis) also grew on the summit. It seems like I’m seeing this little beauty everywhere I go this summer and it makes me wonder if it doesn’t like a lot of rain like we’ve had this year, even though it grows in sandy waste areas.

Zigzag goldenrod (Solidago flexicaulis) was a real surprise because it usually grows in wooded areas instead of out in the open.  It has wide leaves and smallish flowers that grow from the leaf axils and at the terminal end of its zigzagging stem.  Zigzag goldenrod grows in the shade and prefers moist soil, so this seems like an odd place to have found it. It grew beside a large stone so maybe the stone keeps it shaded for part of the day.

We had torrential rains the day before I made this climb so I thought my little friends the toadskin lichens (Lasallia papulosa) would be happy, but most of them weren’t. I don’t know if they just dried out that quickly or if overhanging tree branches kept the rain off them. They grow in just about full sun so I suppose they could have simply dried out. The example in the above photo was close to what I expected but it still wasn’t that deep, pea green color and I could tell that it was drying out. When at their best these lichens are very pliable and feel like an ear lobe, but when dry they feel crisp like a potato chip. This one was somewhere in between.

This one was ashy gray and very dry. You can see the broken edges top and bottom where it has snapped like a brittle chip. I have to say that, though I doubt the lichens enjoy being in such a state, I think they’re at their most beautiful when they look like this. I wish I could see them every day so I could witness all of their changes but I’ve seen them only on the summits, so if you want to visit with them you have to work for the privilege.

To those who have struggled with them, the mountains reveal beauties that they will not disclose to those who make no effort. That is the reward the mountains give to effort. And it is because they have so much to give and give it so lavishly to those who will wrestle with them that men love the mountains and go back to them again and again. The mountains reserve their choice gifts for those who stand upon their summits. Sir Francis Younghusband
