Posts Tagged ‘Scattered Rock Posy Lichen’

John Muir once said “The mountains are calling and I must go.” To be honest I never paid much attention to that statement until the mountains started calling me. And as anyone who has climbed them knows, they do call; they kind of get under your skin and won’t stop calling until you answer them, so last Saturday I drove north to Stoddard to climb Pitcher Mountain. Pitcher Mountain gets its name from the Pitcher family, who settled this land in the 1700s. As mountains go it’s a relatively easy climb, even for someone who uses inhalers as I do. The last time I climbed here was in January. On this day the weather was considerably better and the spring greens and singing birds reminded me what a wonderful thing this life is.

Pitcher Mountain is known for its blueberry bushes; thousand of them grow here and people come from all over to pick them. On this day the buds hadn’t even opened yet, showing what a difference elevation makes. Down in Keene they’re in full bloom.

Hobblebushes (Viburnum lantanoides) grew beside the trail and how very beautiful they were. Though like blueberries they’re also in full bloom in Keene, up here the fertile center flowers hadn’t shown yet. Only the much larger infertile outer flowers had opened.

One of the reasons I wanted to come here was to become more familiar with my new camera. Anyone who knows their way around a camera should be able to use just about any camera handed to them, but they all have their little quirks that take time to learn and iron out. This one doesn’t have image stabilization but the lenses do and that’s something I’ve never encountered. On this day the sun was bright and the contrast high, and that’s a challenge for any camera but I thought this one performed reasonably well as this shot of a wild sarsaparilla plant (Aralia nudicaulis) and its shadow shows. The light green oval leaves belong to Canada mayflower, which will be blooming soon.

My first stop along the trail is always the meadow, where if you look behind you, you can often find a good view of Mount Monadnock over in Jaffrey. It was fairly good on this day, I thought.

The meadow is also where you get your first inkling of how high up you are. The views seem to go on forever.

The meadow is large and sometimes you can find it filled with beautiful Scottish highland cattle. I’ve often thought that they must have the best views of anybody who comes here.

The trail is in a U shape and you take 2 left turns to reach the summit. After the meadow the trail, which is actually a road used by the forest rangers, gets very rocky. There are also lots of exposed roots so if you come here you would do well to wear good hiking boots with plenty of ankle support.

I was stunned to see spring beauties blooming (Claytonia virginica) up here because I’ve climbed this mountain more times than I can remember and I’ve never seen them before. My timing was off, that’s all, and I might have missed them by a day or a week. There was a nice little colony of them in this spot just below the summit. Tucked in snug they were protected from the worst of the wind.

Violets and strawberries grew along the trail and even down the center of it, where many had been stepped on.

The fire tower, manned on occasion, loomed at the summit. This is the second tower on this spot; the first burned in one of the largest forest fires this region has ever seen. That’s why I call it a monument to irony.

The old fire warden’s cabin still stood solidly but there was something different about it.

The difference was a gaping black hole where the last time I was here a board covered the window. It looked like vandals had been here but with so many people climbing this mountain I can’t imagine them getting away with it.

I don’t condone vandalism but realistically bears have been known to break into cabins countless times in this area so it’s anyone’s guess as to how this happened. I wasn’t about to pass up what was probably an only chance to see inside a ranger’s cabin though, so I turned on the flash and took a couple of photos. It looked like it had been furnished in the 1940s, and that was no surprise. I’m assuming there was no running water here because there is a privy in the back, but there was electricity.

If when you reach the tower you turn almost 180 degrees you’ll see another decent view of Mount Monadnock. You can also see the meadow in this view. On this day it was so gusty up here I could hardly stand still. I wanted to crouch on the ground so the wind couldn’t catch me.

But in a way the wind was welcome because it blew away all the black flies that had plagued me all the way up the trail. For those unfamiliar with them black flies are very small biting insects that appear for a few weeks in spring, hatching out of clean running water unlike the mosquito, which hatches out of still, stagnant water. Black flies feed on the blood of mammals for nourishment and they usually come in swarms. Bug spray helps keep them away.

What I call the birdbaths are natural depressions in the stone. With all the rain we’ve had I doubt they’ve been dry a day in the past two months. I once sat and watched a dark eyed junco take a bath here, and I was able to get a few shots of it splashing around. The blue of the sky deepens as it is reflected in these pools and it makes a simple puddle as beautiful as any jewel.

There are lots of lichens growing on the rocks of the summit and one of my favorites is the scattered rock posy (Rhizoplaca subdiscrepans.) They 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 always tell myself that I’m going to come up here with a compass and a topographical map so I can name all of the surrounding mountains but I never do. I don’t suppose it’s that important anyway. I’d rather just sit and look around, especially when I have the whole mountain to myself as I did on this day. I expected it to be crowded up here but there wasn’t a soul in sight. I wondered if the flies kept people away.

It’s hard to tell from these photos but there is still snow on the ski slopes over there in Vermont.

I stayed on the summit for awhile trying different things with the new camera until my legs felt less rubbery and then I hit the trail again. I don’t know why going down always seems harder than going up, but my legs usually let me know that they aren’t thrilled by it.

The meadow is just to the left of the trail in that previous shot and as I looked out into it I thought a highland cattle calf had somehow gotten loose and was in the meadow eating grass but then wait a minute; that wasn’t a calf. As soon as it looked at me and sniffed the air with its snout I knew it was a black bear. And it was another big one. Though it might look far away in this photo it could have reached me in seconds. Black bears can move incredibly fast; 50 feet per second in fact, so running from one is pointless.

I’ll be the first to say that this is one of the worst photos I’ve ever shown on this blog but you can clearly see the roundish ears and long tan snout of a bear. You don’t have much time to fiddle around with a camera when a bear is staring at you like this and I didn’t have the zoom lens with me anyway, so I just took a couple of quick shots. I just went through this with another bear in Westmoreland and that one didn’t scare any more than this one did. It stood and stared and sniffed, just like this one. And just like that time once again I was the only human around, carrying no bear spray and with only one way out. Luckily this one turned into the forest while I wondered what I was going do if it started toward me, so I hoofed it back down the mountain somewhat faster than I usually do, slipping on loose stones and tripping over roots the whole way. It’s hard to walk downhill when you’re looking back over your shoulder I’ve discovered, and I don’t recommend it.

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

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

Two of my great loves are history and botany and one of the best ways I know of to get a good dose of both is by following stone walls. This particular wall is in Swanzey, New Hampshire and surrounds what I believe is the oldest cemetery in town. Revolutionary war soldiers are buried here so it certainly has some age.

Right off I spotted some 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.

There are stone walls called “lace walls” which are built of a stack of stones just one stone wide, and which are full of holes that make them look like lace, but this is a tossed wall sometimes three or four stones wide and it was built to keep animals, probably sheep, out. There were no holes when it was built but there are now, as this photo shows. I can’t explain how it happened but I’ve built enough dry stone walls to know that building a hole like this one into a tossed wall would be close to impossible. In a tossed wall the stones are literally just tossed on top of one another. The object wasn’t to build a pretty wall; it was to get rid of the stones as quickly and efficiently as possible. I think a stone must have fallen or been taken out of the wall to create such a hole.

There are a lot of tree stumps along the wall and some of them, like the one above, are very old. Not only was this one covered with moss and lichens, it also had birch trees growing out of it. Stumps like this are always worth a second look.

The old stump had 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 spots to find them.

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

A large pile of sand at the base of another hollow tree stump meant that something was living under it. Possibly a ground hog, but I didn’t see a single paw print.

This old maple tree was covered on its sunny side by whitewash lichen (Phlyctis argena.) This is a tough, crusty lichen that is fairly common on hardwood tree bark. They can cover quite a large area and make the tree look as if it has been painted, hence the common name. They can be greenish white, silvery, or bright white.

As time passed barbed wire was often added to stone walls to keep animals in or out. Stone walls were usually too low to be effective and cows and other farm animals often jumped right over them, so their height was increased by adding wire or other materials. You had to pay a fine if your animals escaped and were caught roaming free. They were brought to the town pound and the owner had to pay to get them back. This wire grew out of the very center of a pine tree, so it has been here for quite a while. Running their saw into steel wire is one of a wood cutter’s worst nightmares come true but many things have been found inside trees, from axe heads to gravestones to even bicycles.

Every time I see rusty old barbed wire stapled to a tree I think about a book I read by a man who lived in a cabin in the Massachusetts woods. He said that one of his favorite things to do was run through the woods at night. He wouldn’t want to do that here. I wouldn’t even run through these woods in broad daylight because much of what is now forest was once pasture, and there is a lot of barbed wire out there.

Peppered rock shield lichen (Xanthoparmelia conspersa) 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.

Scattered rock posy lichens (Rhizoplaca subdiscrepans) on the other hand, are 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.

Sometimes it isn’t what is on the stone that interests me, it’s the stone itself. I’m not sure if this pattern was on the stone or part of it but it was very interesting. Also interesting was how it had absolutely nothing growing on it when all of the stones around it had mosses and lichens growing on them.

I never knew my grandfather but I do know that he made his living as the town blacksmith in Westmoreland, New Hampshire, and this old horse hitching ring brought thoughts of him to mind. If he was lucky a blacksmith might make a dollar a day but very little cash changed hands in colonial America so he most likely would have been paid in food, charcoal for the forge, lumber, or something else he needed. In the early 1800s blacksmiths charged anywhere from 2 cents for an axe wedge to $5.50 for all of the ironwork on a new wagon. That would include springs, axles, brakes, and rims for the wheels. I have a photo of my grandfather working on a wagon wheel in his blacksmith shop. The wheel sits on top of a big wooden keg that he probably made the iron hoops for. I hope he was paid more than they were in colonial times.

Some of the stones in this old wall are not natural, meaning they were cut or quarried. There is a large granite outcrop just up the hill from this spot and stone was taken from it using star drills and sledge hammers, I would imagine. The marks of the old hand drills are still easily seen on some of the stones. It’s unusual to see both natural and cut stones together in a wall; usually they’re made of one or the other but the farmer could have been trying to increase the height of his walls.

Some of the quarried granite was used for fence posts. Four posts were put in around certain family plots in the cemetery and chain hooks were added by drilling a hole into the top of each post and hammering a hook into the hole.  I’m not sure if friction alone held the hooks in the holes or if cement was added to hold them, but after over 200 years they are still solid and immovable.

Once chain was added the family plot was enclosed but still visible to anyone trying to find it. This chain looks like it was hand wrought.

Blacksmiths don’t cast iron; they soften it by heating it in a forge and then shaping it with a hammer, and I love how you can see all the hammer blows on this chain hook. I also love how the smith fashioned something as simple as a chain hook into what looks like a dragon’s tail. He didn’t have to do this; it was extra work that he probably wasn’t paid for, but he was good and would have wanted people to know his work. If I needed ironwork done and I saw this hook and the ones in the previous photos I would have chosen the smith who made this one. It’s a beautiful thing which, if I owned it, would be considered a work of art.

Sometimes these posts wander in unplanned directions and almost write themselves, and this is one of those; l felt as if I were just along for the ride instead of the one doing the writing. It began in the old cemetery and I just tagged along with the camera while the story wrote itself in my mind, so I hope you won’t mind that there is a little more history than botany in this one. Though I expected the post to be full of mosses and lichens for me the history I found was a refreshing diversion while I wait for spring flowers to appear, and thoughts of my hammer wielding grandfather ran all through the day. I wonder if he ever imagined that one of his grandsons would grow up to be a stone wall builder.

Stones are all about time—time to find them, to move them, to place them, and time, occasionally, to chisel and shape them. And above all, time to see them, experience them, and fall under their spell. ~Charles McRaven

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

1-stream-ice

I visited the otter pond recently, trying to figure out how he would come and go. This small stream feeds into the pond but it’s too shallow and narrow for an otter to swim in. It had some beautiful patterns in its ice though.

2-icy-pond

The reason I wondered about the otter is because its pond is completely frozen over with no holes like there were the last time I saw it in December. Where do otters go when this happens, I wonder?

3-stress-cracks

All of the thawing and re-freezing has left the ice as smooth as glass, but the warm weather has made it too thin to skate on. The two dark spots show little to no thickness and there were thin ice signs where people skate. I’m sure there are a few dozen frustrated skaters it town because of it.

4-burdocks

I saw some burdocks and remembered how Swiss engineer George de Mestral got the idea for Velcro from the sticky burrs lodged in his dog’s coat. I wondered why I didn’t think of such things.

5-burdock

This is where the hook part of the “hook and loop” Velcro fasteners came from. I’ve never seen it happen but I’ve heard that small birds can get caught in burdocks and then can’t escape. That could be why there were no seeds missing from these examples; maybe the birds have learned to stay away. According to John Josselyn, a visitor from England in 1672, the burdock came to this country as burrs tangled in cow’s tails, but if that is true then how did Native Americans know the plant so well? They used the entire plant as food or medicine and made a candy-like treat from burdock roots by slicing them and boiling them in maple syrup. They stored much of it for winter.

6-coneflower-seed-head

Birds aren’t staying away from coneflower seeds. I always let coneflowers (Echinacea purpurea) go to seed. Goldfinches, cardinal, blue jays and other birds love to eat them. I’ve never seen a bird on them but the seeds disappear and there is often a pair of blue jays in the yard.  Many butterflies and bees also love its flowers, so if you’re looking to attract the birds and bees, this is one plant that will do it. The Echinacea part of the scientific name comes from the Greek word echinos, which means hedgehog, and refers to the spiny seed head.

7-british-soldier-lichen

An old pine stump was red with British soldier lichens (Cladonia cristatella.) This lichen also grows on bark or soil and is often seen where people live because it is extremely tolerant of pollution. Because of that and its bright red color it is said to be the best known lichen in the eastern United States. I’ve even seen it growing on buildings.

8-british-soldier-lichen

The spore bearing apothecia of the British Soldier is very red with a matte rather than shiny surface. The biggest among this grouping could have easily hidden under a pea.

9-sidewalk-firedot-lichen

If you spend time walking along stone walls eventually you’ll see a stone with a splash of bright orange on it. This is 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.

10-sidewalk-firedot-lichen

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. I think this is the first time I’ve seen it do so.

11-scattered-rock-posy-2

I had to visit my old friend the scattered rock posy lichen (Rhizoplaca subdiscrepans) that I’ve been watching grow for several years now. It has gone from penny to quarter size (0.75-0.95 in) and is both beautiful and unusual with its brain like body (Thallus) and orange fruiting discs (Apothecia.) I always find them growing on stone in full sun. This is a lichen that never seems to stop producing spores; its orange pad like apothecia are always there.

12-blueberry-buds

If you’re stuck in the winter doldrums and feel the need for some color, just find a blueberry bush; everything about them is red, except the berries. Part of the reason the earliest English settlers survived New England winters in Plymouth was because the Native Americans of the Wampanoag tribe showed them how to dry blueberries for winter use. Natives used the dried berries in soups and stews and as a rub for meat. They also made tea from the dried leaves. More than 35 species of blueberries are native to the U.S.

13-amber-jelly

Amber jelly fungi (Exidia recisa) have started to appear on downed trees and limbs. You can’t tell from this photo because these examples were frozen solid but this fungus has a shiny side and a matte finish side. The spores are produced on the shiny side and if I understand what I’ve read correctly, this is true of most jelly fungi. This one has the color of jellied cranberry sauce. Jelly fungi can absorb up to 60 times their weight in water, so if a weakened branch is covered with them as this oak limb was, it doesn’t take much of a wind to bring the heavily weighted branch and the jelly fungi to the ground. Jelly fungi are a signal that the tree’s health isn’t good.

14-indian-pipe-seed-head

Indian pipe (Monotropa uniflora) seed pods look like beautiful carved wooden flowers that have been stuck into the snow. Most have split open by now into 5 separate parts to release tens of thousands of seeds to the wind. Each individual seed is only ten cells thick. Indian pipes are parasitic on certain fungi, which in turn are often parasitic on the roots of trees so in a roundabout way they get their food from trees.

15-tinder-fungi

Tinder polypores (Fomes fomentarius), also called horse hoof fungus, grew on a fallen log, but didn’t grow on the tree while it was standing. I know this because their spore bearing surfaces pointed towards the ground. If they had grown before the tree fell then their spore bearing surfaces would appear perpendicular rather than parallel to the ground. This bracket fungus produces spores at all times of year but through spring and summer studies have shown that as many as 800 million can be produced in a single hour. The fungus is also known for its ability to stop bleeding and was recommended for that purpose by none other than the father of medicine himself, Hippocrates (460 – 370 BCE).

16-twisted-log

I’ve searched and searched for the answer to why some trees twist when they grow and the short answer seems to be; nobody really knows. What is known is that the wood is often weaker and boards cut from spiral grained trees often twist as they dry, yet while the tree is standing it is more limber than a straight grained tree and is better able to withstand high winds. Scientists have also found that spiral growth can be left or right handed and both can sometimes appear on the same tree. Though spiral growth appears in the trunk, limbs and roots of some trees you often can’t see it until the bark comes off.

17-ice-on-a-log

It’s easy to believe that a fallen tree is just an old dead thing that is slowly rotting away but as the icicles on this example show, there is life in it yet.

18-raspberry-cane-2

It’s always a pleasure to see the beautiful blue of first year black raspberry canes in winter. The color is caused by a powdery wax which can protect the plant from sunburn, prevent moisture loss, or help shed excess water. In botanical terms, a plant part that looks like this is said to be glaucous, which describes the whitish blue color.

19-blue-jay-feather

The blue of this blue jay feather rivaled that of the black raspberry cane. I don’t see many blue feathers so I was happy to see this one.

20-blue-jay-feather

I was even happier when I looked a little closer. Seeing it up close revealed many things about blue jay feathers that I didn’t know. Chief among them was how very beautiful they are.

1-trail

Each year at this time I start thinking that if I could just get up above the trees the colors would be better or brighter somehow, but they never seem to be and I’ve never been really happy with any photo that I’ve taken that way. But maybe this time would be different, I hoped. The weatherman told me that we were at the peak of our fall colors, so last Saturday I decided to climb Pitcher Mountain in Stoddard to try again.

2-striped-maple-leaf

I kept seeing dark spots on the fading, pale orange striped maple leaves (Acer pensylvanicum) so I had to take a closer look. The quarter size spots were made up of many smaller specks.

3-striped-maple-leaf

I haven’t found a reference to anything similar so I can’t say what they are at this point. They looked like hardened drops of a liquid but I doubt the leaves would weep in such concentrated areas and not all over. If you know what they are I’d love to hear from you.

4-torn-mushrooms

Something ate these little brown mushrooms and tore the stems when they did so. I’ve never seen this before and I’m not sure what animal would do it. There is everything from chipmunks to moose to bears in these woods so without tracks or other clues it’s hard to know. I do know that many kinds of little brown mushrooms can make a person very sick, and some can kill.

5-pasture

A pasture appears on the right side of the trail and I always stop here for a breather. The farm that owns this land raises Scottish highland cattle and my hopes of seeing them were raised by the regular snapping of an electric fence at just about knee and waist level, but the cattle never showed up. I had to pay attention so I didn’t get tangled in that fence with my metal monopod, so maybe it’s a good thing they didn’t.

6-trail

The trail takes a sharp 90 degree left turn and parallels the pasture for a time. It also becomes quite rocky in this stretch. Not far after the turn, maybe a hundred feet or so, there is a break in the trees and brush to the right. If you follow this short path after just a few steps you come to a good view of Mount Monadnock on the right. And the electric fence in front of you.

7-monadnock-from-trail

The reason I chose Pitcher Mountain is because it has a full 360 degrees of viewing area on its summit. If the light is harsh in one direction as it was in this shot of Mount Monadnock from the trail, it often isn’t quite so harsh in a different direction. At least that’s what I was hoping. Finding correct exposure settings can be tough with some colors in such bright light.

8-beech

Beech trees are starting to turn and they seem to be right on schedule. Though they are among the last to turn along with the oaks, most had turned fully by Halloween last year.

9-fire-tower

Before too long the fire tower glimpsed through the trees tells you that you’re very near the summit.

10-ranger-cabin

The old fire warden’s cabin might be in for a rough ride this winter if nature decides to make up the 15 inch rain deficit with snow. Though I’ve climbed up here in the winter several times if that happens I probably won’t be up here to see it.

11-pasture-from-above

You can turn and look back just above the warden’s cabin to see the pasture from above, along with Mount Monadnock in the background. The view from the summit to Monadnock would be almost directly south.

12-fire-tower

The fire tower is the second one to stand on this peak. Ironically the first wooden tower built in 1915 burned in April of 1940 in a fire which destroyed 27,000 acres of forest, including the tower and all of the trees on the summit. It was the most destructive fire in the region’s history. Stout cables keep this one from blowing off the mountain but there is still little to protect it from a large fire.

13-near-hill

If you’re standing where I was in the previous photo looking at the tower and walk around to the left side of it, what I call the near hill seems to be close enough to touch. I don’t know its name or if it even has one.

14-summit-colors

It was hard to pay attention to far off colors when colors like this were so close by on the summit.

15-scattered-rock-posy

Scattered rock posy lichens (Rhizoplaca subdiscrepans) added to the orange colors of fall. I was thinking one day about how we rarely see orange in nature for most of the year but then all of the sudden we are saturated with it in the fall. The orange pad like parts of this lichen are its fruiting bodies (apothecia) and the grayish, brain like part is the body (thallus.)

16-crater-lichen

Black and white crater lichens seemed to stare back at me from the stones. I think they are Diploschistes scruposus, simply called crater lichen after their cup shaped black fruiting bodies (apothecia,) which are surrounded by a stark white or gray body (thallus.) They grow on exposed rock all over the earth, even in the Polar Regions.

17-blueberry

Pitcher Mountain is known for its blueberries, and they turn a beautiful red in the fall. They supply most of the red that can be seen in the near distance in many of these photos.

18-blueberries

There were a surprising amount of berries that the birds and pickers had missed, but they were shriveled.

19-fall-colors

As far as the eye could see the trees were turning. I’m surprised to see how many more deciduous trees than evergreens there are in this photo.

20-unknown-mountain

I’m not sure what the name of the mountain in the distance is but it seemed to be higher than the one I was standing on and it wasn’t Mount Monadnock. It was quite far away but unfortunately I didn’t pay any attention to what direction it was in.

21-birch

This birch tree was almost leafless but its comrades more than made up for its lack of color. It seemed a kind of exclamation point, as if colors like these needed to be emphasized.

22-summit-colors

I think this photo is my personal favorite from that day because it has all of the colors I saw in it. It also shows the incredible beauty that can be found up here.

23-natural-birdbath

It seemed strange to see the natural birdbath full of water in the middle of a drought; it must have rained recently. I’m sure the many birds that I heard are very grateful.

I’m sorry that this post was so photo heavy but our autumn “season” is really very short and we’re lucky if we see three weeks of the kind of colors that I saw on this day, so I went a bit overboard. Though I don’t usually climb strictly for the views on this day that’s what I came for and they were very good, with little haze.

To see what others cannot…
You must climb the mountain.
