Posts Tagged ‘Lichens’

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

The rapidly dropping leaves told me if I was going to climb to see the foliage colors from above I’d better get a move on, so on the 14th I drove over to Pitcher Mountain in Stoddard where there is a 360 degree view from the summit. I’ve been having some breathing problems lately and I really didn’t know if I could make it to the summit or not, but I threw caution to the wind and with a good puff on the old inhaler, up I went. Sorry about the lens flare but it was a beautiful sunny day.

There were plenty of opportunities to stop and catch my breath and that was a good thing because if I went by the amount of people coming down as I was going up, it must have been standing room only up there. I’d bet I passed at least twenty people. This photo is of an oak that was already changing into its fall colors.

Beeches are also changing and they along with the changing oaks tell me I had better get over to Willard Pond soon. Willard Pond is especially beautiful at this time of year with its hillsides of yellow beeches and orange, red and purple oaks.

The trail up Pitcher Mountain is short but steep in places and when you feel like you are carrying a weight on your chest it seems even steeper. Pitcher Mountain is named for the Pitcher family who settled here in the mid-1700s. There are still remnants of an apple orchard near the summit, with trees that still bear apples. I doubt they’re from the 1700s but they are quite old.

This is always a stopping place, breathing problems or not. I always feel a great sense of release when I see this view and can imagine I hear a great whooshing sound, as if everything has suddenly been stripped away. There is the earth, the sky, and nothing else but emptiness, and when you’ve lived 60+ years surrounded on all sides by thick forest that emptiness can be very welcoming indeed. I sat on a stone and basked in it and forgot myself for a while.

When I got moving again a blueberry bush on the side of the trail had been caught in a sunbeam, and it was beautiful enough to stop me in my tracks.

While I was admiring the blueberry bush I looked up and saw what I think was a rosy saucer lichen (Ochrolechia trochophora) on a tree. It was full of beautiful rosy brown apothecia and was producing spores to beat the band. If I hadn’t stopped to admire the blueberry I wouldn’t have seen it.

At the base of the tree with the rosy saucer lichen was a log with a peach colored turkey tail fungus (Trametes versicolor) growing on it, so of course I had to get a photo of it. I don’t see many of them this color. One thing leads to another in nature; the blueberry showed me the lichen and the lichen showed me the turkey tails. I wander like this from interesting thing to interesting thing quite regularly. It’s as easy as looking around closely before you leave any given bit of nature. Before you move on down the trail there’s a good chance that you’ll see something else that catches your eye.

Almost there. Enough dilly dallying.

I was high enough now to look out over the forest I had just come through. It’s called the Andorra Forest and it seems to stretch into infinity. Views like this one in the fall let you pick out individual trees because of their varying color and show just how staggering the number of trees here really is; 4.8 million acres of them.

I could just glimpse the fire tower through the glowing blueberries and sumacs.

From here on is the shortest but steepest part of the trail so I stop at the old ranger’s cabin to catch my breath and prepare for it. I don’t know the history of this cabin but it’s certainly big enough to have held at least 4 people at one time. I’m assuming that people lived here when the fire tower was manned daily. The cabin looks like it’s leaning even more to the left, into the mountainside. How it takes the heavy snow load each winter is anyone’s guess.

Just a few more steps and I’d be on the summit. I was happy (and a tiny bit surprised) that I’d made it. I call the fire tower a monument to irony, because in 1940 the original 1915 built wooden tower burned to the ground, along with 27,000 acres of forest and all the trees on the summit. It was one of the worst fires in state history but it is because of that fire that today we have a full 360 degree view from the summit.

The bedrock showing on the summit is covered in lichens.

Common goldspeck lichen (Candelariella vitellina) is a crustose lichen, which means it grows like a crust and probably couldn’t be removed without damaging whatever it is growing on. This lichen contains a yellow pigment called calysin and was once used to dye wool yellow in Sweden. It must have been very hard work scraping it off the stone and yellow wool must have been very expensive.

One of the first things I look for at the summit is what I call the “near hill.” I was a little disappointed that the colors weren’t brighter and didn’t “pop” more. Capturing fall color from above is a lot harder than one would think. I’ve tried many times, from many different hills and mountains, and I really haven’t ever been completely happy with the results.

It was very beautiful up close but harder to see the colors far away.

I could just see the whirligigs over on Bean Mountain in Lempster. I couldn’t tell but they must have been spinning fast. The wind was brisk to say the least, and the camera had a hard time with them through the haze.

Jerry from the Quiet Solo Pursuits blog thought the fall colors would look better with a blue sky behind them so I conjured a bluish one up and here it is. I told Jerry that I found when the sun is behind me a photo will almost always show blue water, and I wondered if the same might be true with the sky. As you can see from these photos in many the sky is milky white and in some it’s blue, and I think it must have a lot to do with where the sun was when I took the photo. I’m going to have to pay closer attention to see if it really does work that way. By the way, if you’re a nature lover, especially a bird lover, you really should be reading Jerry’s blog. You can find him right over there in the “Favorite Links” section under Quiet Solo Pursuits. His latest post shows the glorious fall colors found in Michigan.

I met some people from Stoddard up on the mountain who told me I had missed the peak colors by just a few days. “Last Tuesday was best,” they said. Oh well, as Forrest Gump’s momma always said: Life is like a box of chocolates, you never know what you’re gonna get.

It had rained the day before my climb so I wasn’t surprised to see the depressions in the stone filled with water. I’ve always called them bird baths and a year or two ago a dark eyed junco let me sit and watch it bathe right here.

There was another oak turning orange and prodding me on to Willard Pond so I don’t miss the show there. We’re not done yet; there is more fall color to come. The oaks there blaze with bright orange and the beeches are lemon yellow and together they often put on an unforgettable show.

Going down was easier on the lungs but harder on the legs and I guess that’s the price you pay for climbing. I had a smile on my face though and I had met a few interesting people and had seen many beautiful things, so I’m not sure I could imagine a better day. I hope you’ll have one just as good real soon.

Last Sunday I woke with an urge to climb, so I headed 25 miles north to Stoddard where Pitcher Mountain lives. Since we have no snow in Keene I assumed there would be no snow there, but I was wrong. It was another one of those “what was I thinking?” moments.

But all in all the trail wasn’t bad because it was snow instead of ice. I stopped to get a photo of target canker on a red maple (Acer rubrum.) If I understand what I’ve read correctly red maples are the only trees that get this canker. It makes the tree’s bark form bullseye shaped raised plates that look like a target, but it doesn’t really hurt the tree. The circular plates are the tree’s response to a fungus that invades the healthy bark and kills it. During the next season the tree responds with a new layer of bark and cork (callus) to contain the fungus. In the next dormant season the fungus again attacks and kills more bark and on it goes, a seasonal alternation of pathogen invasion and host defense response which creates concentric ridges of callus tissue; a target canker. Finally the fungus gives up or dies off and the tree grows on. Red maples have beautiful deep red flowers and the trees often grow in large colonies, so I was hoping to see huge swaths of red from the summit.

I also stopped to see a striped maple (Acer pennsylvanicum) that grew along the trail. The two large terminal bud scales had started pulling apart to reveal the bud within, just like they were doing 25 miles and over 1,600 feet lower in Keene. The pink and orange fuzzy buds are very beautiful and I’m getting anxious to see them. It won’t be long now.

I had to stop at one of my favorite places, which is the pasture about half way up the trail. I always imagine doors being thrown open and a great whooshing sound when I see this view because it’s so expansive compared to the close woods where I spend most of my time. It’s a peaceful, simple place with just the earth, sky, and you and you can step outside yourself for a while here.

The trail takes a turn after the pasture and gets steeper and rockier as it follows it uphill. On this day I had a choice; mud on one side or snow on the other. I chose the snowy side.

There is a fairly good view of Mount Monadnock from this leg of the trail but low haze often spoils it. It wasn’t too bad on this day.

There is a lot of black knot disease on the black cherry trees (Prunus serotina) here and I stopped to look at an example. Black knot is caused by the fungus Apiosporina morbosa which can also attack plums, peaches, and apricots. Spores from the fungus are spread by rain or wind and typically will infect trees from April through June on new growth. Infected stems swell up and produce hard black knots like those in the above photo. The disease can eventually kill the tree so infected limbs should be pruned off 2-4 inches below the knots and buried or burned before bud break the following spring.

This is what black knot can do to a fully grown black cherry. This is a wound that never heals and on a tree this age and size the disease is impossible to control and the trees should be destroyed so the fungus can’t release anymore spores. If this photo looks a little strange it’s because I had to use the flash because it was so shady here.

You can get a glimpse of the fire tower from a good distance away before the trees leaf out, but the glimpse signals the start of the steepest part of the climb. The trail had a little snow on it but the summit was snow free, bare granite as usual.

The old forest fire warden’s cabin still stands but each year it seems to lean into the mountainside just a little more. Staying up here must have been hard work no matter what time of year it was.

Pitcher Mountain is one of just a handful of places I know of where Mountain ash trees (Sorbus americana) grow naturally. These trees are easy to identify when they don’t have leaves by their big black buds. This example was just starting to turn green. Mountain ash is used ornamentally because of its white flowers in late spring and bright orange berries in the fall, but it is a native tree. Native Americans made a tea from the bark and berries of this tree to treat coughs, and as a pain killer. They also ate the died and ground berries for food, adding them to soups and stews. The berries are said to be very tart and have an unpleasant taste when unripe.

The fire tower was unmanned and so was the summit so I had the whole rock pile to myself, which is a very rare thing. You find people on most mountaintops in this area and popular ones like Mount Monadnock can at times seem as busy as a Manhattan sidewalk. I call the fire tower on Pitcher Mountain a monument to irony because the original wooden tower built in 1915 burned in April of 1940, in the most destructive forest fire to ever strike this part of the state. Twenty seven thousand acres burned, including the tower and all of the trees on the summit.

A couple of weeks ago we had strong winds with 60 mile per hour gusts and a lot of trees fell in certain areas, so it’s probably a good thing that the fire tower is fastened to the granite of the summit with several stout cables. The wind that day must have made it impossible to stand on the summit. I can imagine the cables vibrating like violin strings in weather like that.

The hill that I call the near hill might be the closest but it would still be quite a hike to reach it. I was surprised by the amount of snow still on it.

I love seeing the blue hills off in the distance and though I don’t climb for the view they do make it much more enjoyable. In case you’re wondering about my not climbing to see the view, if I did I’d be disappointed probably 80% of the time because you never know what haze, humidity, or weather in general will do to it. For instance on this day, though it looks like I could see clear to California, I couldn’t see the windmills over on Bean Mountain just a few miles away.

But I could see the shading on the hills and this is something I find very pleasing. I sat and admired them for a while.

I could also see ski areas on several distant mountains, none of which I know the name of. Skiers must be enjoying some fine spring skiing this year.

Common goldspeck lichens (Candelariella vitellina) grow profusely all over the bedrock up here. This crustose lichen is very granular and is often busy producing spores, but I didn’t see any of its fruiting bodies (apothecia) on this day. These lichens were once used to dye wool in Sweden but I can’t imagine how they got them off the rocks. Crustose lichens usually can’t be removed from the substrate they grow on without damaging it in some way.

I’m not sure what it was but the sun brought out golden highlights in this tiny insect’s wings. It was hanging on desperately trying not to be blown away in the strong wind, so I was able to get a shot of it. I’d guess that it was hardly more than a quarter inch long.

Tile lichens are areolate lichens, which are made up of many little lumps or islands. In the example above the black parts are its apothecia and the white parts are the body (Thallus.) The apothecia are even with or slightly below the surface of the thallus. Tile lichens grow on exposed rock in full sun and will even grow in winter if the temperature is slightly above freezing. I think this one might be Lecidea tessellata but with 136 species of tile lichens I could easily be wrong.

The natural depressions in the bedrock that I call birdbaths always have water in them, even when we had a drought two years ago, and that seems strange to me. What I think doesn’t matter though, because the birds do use them; last year I watched a dark eyed junco bathe in this small pool. I was a little disappointed at not seeing the large swaths of flowering red maples that I hoped to see from up here but even so I saw plenty of other beautiful things, and it was a great day for a climb.

I was shooting photos of a wintery Mount Monadnock when spring hopped into the photo in the form of a robin. He’s there in the grass on the left.

Robins are very curious birds, I’ve found. They seem to like watching what I’m doing as much as I like watching them. I had one let me stand right next to it just the other day.

A raccoon has become a regular visitor to where I work. Somehow it has damaged its paw and doesn’t seem to be able to see very well. We think it must be quite old for a raccoon but it still gets around fairly well and can still climb trees.

Two mallards hid in the reeds in a small roadside pond. While he watched me she tipped up and ate. She ate quite a lot, ignoring me the whole time.

They finally got tired of me watching them and swam off. Ducks and other waterfowl are very wary of humans in this area. They don’t swim right up to you when they see you like they do in other places because nobody feeds them, so getting photos of them is usually tough. This pair put up with me longer than most do.

Activity seems to have increased among all creatures except bees, which I still haven’t seen yet. Squirrels are certainly in abundance; I don’t think I’ve ever seen so many. This one was hopping across a lawn when I tried to get its photo.

I’ve never seen so many pinecones fall as they have this year either. They’ve made a squirrel’s life pretty easy, as this large stone covered with pinecone scales shows. For some reason squirrels usually like to sit up off the ground when they eat and one or more of them ate a lot of pine seeds on this stone.

There was a storm brewing on an ice covered Half Moon Pond in Hancock on March 29th when this was taken.

This is what the pond looked like 14 days later on April 12th. We’re getting just about one sunny day each week and this one was that week’s day. The ice on the pond wasn’t completely gone but there was very little left. It has snowed again once or twice since that photo was taken.

I found what I thought was a toothed crust fungus, but this fungus wasn’t acting like any other crust fungus that I’ve seen.

This crust fungus had developed fruiting bodies that looked like mushrooms with a hollow stem. On the smaller one on the left you can just see the teeth hanging from the underside of the cap. I don’t really know if the toothed crust developed from the mushroom like fruiting bodies or if the mushrooms arose from the toothed crust. Each “cap” was about as big as an aspirin.

On a nearby section of log the toothed crust, if that’s what it is, had completely enveloped the mushroom shaped fruiting bodies. I’ve never seen anything like this and haven’t found anything like it, either in my mushroom guides or online. If you know what it is I’d love to hear from you.

I know what this is; an orange jelly fungus behaving strangely. Orange jelly fungi (Dacrymyces palmatus) are common here and usually grow on fallen eastern hemlocks. They absorb many times their own size and weight in water and usually shrink when they dry out but this one looked like it was melting. These fungi are eaten in China and are said to improve circulation and breathing.

Plantain leaved sedge (Carex plantaginea) is a large plant as sedges go, with wide, pleated, foot long leaves that wrinkle like crepe paper. It’s large leaves are for gathering light so it does well in the shade under trees, where the one pictured grows naturally. Sedges like cooler weather and cool soil, so they grow and flower best in spring in this area. Once it gets hot their growth slows but sometimes in a cool fall they’ll have a second growth spurt. This one is on the rare side here. I know of only a few plants, all growing in one spot.

Plantain leaved sedge usually blooms in mid spring and this plant seems to be right on schedule. It had several beautiful dark purple flower spikes showing. These flowers will open into wispy white female flowers on the lower part of the stalk (Culm) and the long, yellowish male flowers on the upper part. The flowers are called spikelets and the stems that bear them are triangular, and that leads to the old saying “sedges have edges.” I’m guessing that these flowers will appear in a week or two, depending on the weather.

Soil crunching underfoot in the spring and fall is a sure sign that you’re walking on ice needles. For them to form the temperature at the soil surface has to be below 32 degrees F while the soil and groundwater remain thawed. Hydrostatic pressure forces the groundwater, which is sometimes super cooled, out of the soil where it freezes instantly into a “needle.” As more water is forced out of the soil the process is repeated over and over, and each needle grows in length because more water is freezing at its base. I’ve read that each thin needle is hexagonal in shape and that needles 16 inches long have been found, but most of the ones I see are less than 5 inches long. They are often very dirty.

There is a plant called common cotton sedge (Eriophorum angustifolium) but I doubt this is it because another name for it is bog cotton due to its habit of growing in damp boggy ground, and this plant was growing in a spot that was high and dry. It grew at the edge of the woods under pine trees and I’ve never seen anything else like it. It had a single hairy stem about a foot tall with this bit of “cotton” at the top. It had no leaves because of the time of year. If you know what it is I’d love to know.

An eastern hemlock (Tsuga canadensis) was healing a wound in a strange way, I thought. The wound cork had grown over a scar in a kind of lump rather than flat as it usually does. According to the book Bark, by Michael Wojtech eastern hemlock is the only tree in the northeast that grows wound cork in annual increments. Because it grows this way it can be counted just like a tree’s growth rings. From what I counted this scar took 10-12 years to heal. Native Americans used the inner bark (Cambium) of hemlock as a base for breads and soups or mixed it with dried fruit and animal fat to use in pemmican. They also made tea from the tree’s needles, which have a high vitamin C content. This saved many an early settler from scurvy.

I recently went to see one of my favorite lichens, the poplar sunburst (Xanthoria hasseana.) One of the reasons it is one of my favorites is because it is almost always producing spores in its large, sucker like fruiting bodies (Apothecia.) This lichen grows on tree bark near a pond and has a mounded growth habit rather than flat. This example might have been a half inch across. It’s a pretty little thing.

I might have already shown these turkey tail fungi (Trametes versicolor) but I can’t remember. It doesn’t matter anyway because seeing such beautiful things doesn’t have to happen just once. I certainly think they’re worth a second look. As beautiful as they are though turkey tails frustrate me a bit, because I’ve never been able to find out how they come by their color. They have a wide range of colors and something must influence what color they’ll be. I think it might be the minerals in the wood they feed on, but that’s just a guess. I hope you’ll be able to see at least one thing as beautiful this week.

The appearance of things changes according to the emotions; and thus we see magic and beauty in them, while the magic and beauty are really in ourselves. ~Kahlil Gibran

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

It was a nice warm sunny Saturday when I set out for the Beaver Brook Natural Area in Keene and the weather people said it would be sunny all day, but as soon as I got there clouds moved in and decided to stay for a while. Actually the clouds stayed the entire time I was there and the sun didn’t show itself again until I left.

This was the only blue sky I saw the entire time I was there.

But the trail was well packed down and not really as icy as it looks here.

Beaver Brook was roaring. In the summer it giggles and chuckles along beside you but in the winter it roars, and that’s all you hear. Unless it’s covered by ice; when it’s iced over it whispers and is quieter than at any other time.

The brook hasn’t been completely iced over this winter that I’ve seen, but huge ice shelves had formed here and there. You can see how there is nothing under the shelf but air, so it walking out on it would be a foolish thing to do.

The ice shelves had teeth.

I have a lot of old friends living here along the brook, like this smoky eye boulder lichen (Porpidia albocaerulescens.) I see this lichen just about everywhere I go but nowhere else are its fruiting bodies (apothecia) so blue or its body (thallus) so golden. The gold color comes from the minerals in the stone I think, and the blue color comes from the way the light falls on the waxy coating that covers the apothecia. Whatever it is that causes the colors in this particular place, this lichen is one of the most beautiful I’ve seen and this is the only place I’ve ever seen it look like this.

I also stopped to visit the only example I’ve ever seen of stair step moss (Hylocomium splendens.) This is a boreal moss that grows quite far north into the arctic and I’ve seen it here covered with ice, but it isn’t as delicate as it looks and it always comes through winter unscathed. When it’s dry it has a shiny sheen and that’s most likely why another common name for it is glittering wood moss. New growth “steps up” off the midrib of the previous year’s growth and that’s where the “stair step” name comes from. It’s a beautiful moss and I wish I’d see more of it.

The rose moss (Rhodobryum roseum) came through winter looking fine and I was glad of that because this is the only example of it I know of. I did find another small patch on a stone in Swanzey once, but I can’t remember where. It’s nice to know there are more of them out there but I’d still have to call this moss rare. I love its little aspirin size rosettes of leaves that someone thought looked like roses. They look more like dahlias or chrysanthemums to me, but they’re beautiful no matter what we choose to call them.

There were some impressive ice formations on the ledges and I was surprised, because they don’t usually grow so big here. With the up and down weather we’ve had this year though, I probably shouldn’t be surprised by anything weather related.

Last time I came here the brook was flooding in places and it was a downright scary thing to see. The water mark on the far embankment showed just how high the water had been, and I’d guess that it was a good 6 feet higher than it was on this day. I met an old timer up here one day who told me that he had once seen the water over the old road. That’s something I hope I never see.

In places the snow had melted and revealed that there really wasn’t that much covering the road. Since we’re supposed to have warm days all week there’s a good chance that the road will be snow free this weekend.

Where the snow had melted you could see part of the old double yellow no passing lines.

Off on the side of the road a branch had fallen, and it was covered by what I thought at first was milk white, toothed polypores.

But the spore bearing surface of this fungus was more maze like than toothed, so that had me confused until I got home and was able to see the photos. After some searching I came up with what I think is a crust fungus called the common mazegill polypore (Datronia mollis.) It may be common in some places but I think this is only the second time I’ve seen it.

A little further up the road I found another fallen branch that was covered with inch in diameter, colorful crust fungi which I think were young wrinkled crust fungi (Phlebia radiata.)  These are winter mushrooms and that’s the only time I ever see them. They aren’t common; I’ve only found them three or four times. As they age the center of the fungus becomes very wrinkled, and that’s where their common name comes from.

There isn’t anything odd or rare about tinder fungi (Fomes fomentarius,) but a closer look at this one revealed something that was both odd and rare, at least in my experience.

There were squirrel teeth marks ( I think) all over one of the colored bands on it. Recently I’ve seen the same thing on a few lichens and have found that squirrels do indeed eat lichens, and I’ve seen them eating mushrooms but I’ve never seen them do this. It made me wonder if it was algae they were after, because algae grow on both lichens and fungi. I can’t imagine what else they’d get out of scraping their teeth over this fungus unless it was to keep their ever growing teeth in check. Tinder fungi are very tough and woody, so maybe the animal was simply trying to wear down its teeth.

Another fallen branch displayed what I thought from a distance were shield lichens but once I got closer I realized they weren’t anything I had ever seen.

They were obviously not lichens at all, but instead some type of hairy fungi.

They grew like bracket fungi and their spore bearing surfaces were maze like and faced outward. Each flower like cluster like the one shown above couldn’t have been more than three inches across, so they weren’t very big. They were pliable and rubbery to the touch, and felt much like an ear lobe. They look very pink to me but my color finding software tells me they’re mostly tan with some peach puff and dark salmon here and there.

They didn’t have to be big to be beautiful and I thought they were very beautiful things, but after looking through 4 mushroom books and spending several hours online I can’t find anything that even looks close to them, so they’ll have to remain a mystery for now. Maybe one of you knows their name. If so I’d love to hear from you.

Recently we saw nearly 2 inches of rain fall in one day and the placid stream, which is actually called Bailey Brook, that you see in the above photo flooded to cover all of the land seen in the photo and much more. Now that it had returned to normal I decided to follow it for a time and see what kind of damage the flooding had done.

I saw some delicate ice formations.

And stream ice made up of long crystals.

Large chunks of ice had found a place to rest when the flood receded and there they sat scattered here and there, reminding me of glacial erratics.

In some places I thought I was walking on land until my foot went through the ice and found water. From the ice surface down to the soil surface was about 6-8 inches with nothing but air in between, so the stream rose at least that much in flood.

There is a lot of drainage going on in this area and smaller streams meet the main stream in several places. Generally it’s a happy place and a great place to walk with the stream chuckling and giggling beside you, but it can also be a place of great danger when enough rain falls. I’ve seen it flood and go up and over roads in just a matter of a few hours, so you don’t walk here until you’re sure the stream has calmed down after storms makes it rage. First it happened once in ten years, then a couple of more times over the next five years or so, and now it seems to happen each year.

There are still plenty of beech leaves around and I’m glad of that because they add color to the landscape.

A single beech leaf fell and became frozen in the ice. It was a beautiful thing, and it looked like someone had painted it there. It would have been one of the impressionists like Monet or Renoir who would have painted it, I think. It was more light than leaf.

There was something I wanted to see but I had to climb a small hill to get to it. The hill ends right at the stream so there is no level land to walk on. I got up the hill without too much trouble by hugging trees and pulling myself up, but under those leaves was nothing but slippery, solid ice and the only way back down the hill was sitting down and sliding in what I’d guess was a very undignified manner.

But it was worth it because I got to see the horsetails (Equisetum hyemale) that grow along that section of stream. These are ancient plants that are embedded with silica. Another common name is the scouring rush because they are sometimes used to scour pots when camping, and they are also used for sanding wood in Japan. I like the way they look as if someone had knitted them fancy little socks.

There are lots of river grapes growing here along the stream and they are very easy to identify because of their peeling bark. Exfoliating bark is very common on the older wood of many types of grapevines and happens naturally. Older bark cracks from the growth expansion of the newer bark beneath it and eventually the older, cracked bark peels off in strips.

On warm days in the fall this entire area smells like grape jelly because of all the overripe grapes. Birds and animals get most of them but they missed a few, as this photo of a freeze dried grape shows.

I read an article recently that spoke of how we as a people are losing our connection to nature. As of 2008, according to the United Nations, half of all human beings lived in cities and in the U.K. a typical 8 year old child is better at recognizing video game characters than common wildlife. The article mentioned how, not that long ago, people knew trees as well as they knew themselves because they relied on them for heat, shelter, food, and many other things. The article suggested that getting to know trees would be a simple way for people to reconnect with nature, because there are very few people who don’t see trees every day. I suggest starting with easy ones or ones you already know, like the muscle wood tree in the above photo. It’s easy to see why it’s called muscle wood (Carpinus caroliniana.) See how its “tendons” ripple beneath its “skin”? Muscle wood is also called American hornbeam, and its wood is very dense and hard, but learning to identify trees by their bark isn’t hard, and it’s fun. Books like Bark by Michael Wojtech are a great help. You’d be surprised how quickly you would be able to name all of the trees in your neighborhood after a short time.

Here’s another easy one. Yellow or golden birch (Betula alleghaniensis) has peeling bark like a white birch but its bark is kind of reddish brown, which in the right light looks golden. They like cool, moist soil and are usually found near streams and ponds. They can also stand quite a lot of shade so growing here beside this stream in a cool, shaded forest is just about the perfect place for one.

There are a lot of insects after these trees along the stream, including bark beetles. These beetles excavate channels in the wood and when these channels completely encircle the wood the branch or tree has been girdled. Once girdled moisture and nutrients can no longer move freely through the cambium layer. When moisture and nutrients can’t move from the roots to the crown of the tree and back again the tree will die. I see a lot of fallen white pine (Pinus strobus) limbs with bark beetle damage.

Woodpeckers tell me that this standing dead hemlock tree is also full of insects. In large numbers, apparently.

Bittersweet vines twine around tree trunks; they don’t grow straight like this. There is no exfoliating bark, tendrils, or branching like a grape vine would have, so they can’t be that. Since there are no tendrils it isn’t Virginia creeper either. Those are the “big three” native vines that I would expect to find here but if the examples growing up this pine tree aren’t one of them what are they? Poison ivy, that’s what, and it’s a good idea to leave vines you don’t recognize alone until you’re sure of their identity. Poison ivy isn’t poison and it isn’t an ivy. Way back in the early 1600s Captain John Smith thought it looked like the English ivy he had left behind in England and, since it made him itch, thanks to him it became known as poison ivy. The urushiol the vine contains is considered an allergen and there is nothing poisonous about it, but is sure can make you itch and it will give you a rash that might last for weeks. You can get the rash from any part of the plant, including the naked stems seen here.

We’ve probably all heard the old “Leaves of three, let them be” saying about poison ivy, but the plant has no leaves in winter so “Hairy vine, no friend of mine” has to do when there is snow on the ground.  “Hairy rope, don’t be a dope” might work too. The roots seen in this photo are how the poison ivy vine clings to what it climbs, and there will often be a thick mat of roots all along the stem. But not always; poison ivy can grow as a vine, a shrub, or it can creep along the forest floor. It’s wise, if you plan on spending time in a New England forest, to study the plant and know it well. I usually get a small rash on my knees each spring from kneeling on unseen vines growing under the forest litter when I’m taking photos of early spring wildflowers, and I know it well. I’m lucky enough to be little bothered by it but I’ve known people who were hospitalized because of it.

Everywhere I go I see lichens that look like they’ve been chewed on and I’ve tried to find out why with limited success. Reindeer eat lichens but we don’t have reindeer in these woods, just white tails. I’ve seen squirrels eat mushrooms and since fungi are an important part of a lichen I thought that they might be the culprit, but I’ve never found anything in print about it until researching this post. According to a website called “What Do Squirrels Eat” http://www.whatdosquirrelseat.org squirrels have expanded their palates and will eat just about anything, including what we and our pets eat. It also says that they do indeed eat lichens, so I can finally put the chewed lichen mystery to bed.

But it’s rare day when you hike through a forest and do not come away with a mystery, and this was today’s mystery. From the opposite side this looked like a hard gray lump, smaller than the first joint on my little finger, on a poplar limb. When I looked at the underside I saw what appears in this photo. Though I’ve searched for a few days for an identification so far I have no idea what insect made and hatched from it. I’m guessing that it was some type of gall wasp. It might take a few years but one day I’ll find out more about it. In the end I went home happy, because I saw all kinds of interesting and beautiful things and surprisingly, saw no real flood damage at all.

Study how water flows in a valley stream, smoothly and freely between the rocks. Also learn from holy books and wise people. Everything – even mountains, rivers, plants and trees – should be your teacher. ~Morihei Ueshiba
