Beaver Brook in Winter

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.

A path well-traveled may still yield secrets that only one person may discover. ~Anthony T. Hincks

Mosses

I thought I had better visit some of the mosses I know before the snows came and covered them all up and it’s a good thing I did because we’ve gotten several inches over the last few days. You’ll notice in the above photo that mosses grow on soil, on tree bark, and on stone and we’ll look at some of all three in this post.

I thought I’d start with rose moss (Rhodobryum roseum,) which grows on stone and is one of my favorites. This pretty little moss likes limestone so when you see it you know you’re in an area where you might find other lime loving plants, like many of our native orchids. This moss forms dense mats and gets its common name for the aspirin size rosettes of leaves that terminate each stalk. They look like tiny flowers. This is the only example of rose moss that I’ve ever seen and I think it’s probably quite old.

Many mosses will grow on wood, stone or soil and delicate fern moss (Thuidium delicatulum) is one of them. This large stone was covered with delicate fern moss when branches fell on it. That didn’t stop the moss; it just grew right over the branches in its seeming mission to cover all the bare spaces it can find.

Delicate fern moss is a beautiful little thing that isnt as delicate as its name implies, but it certainly is fern like. Here it is crawling up and over one of those branches in the previous photo. The leaves of this moss are often bright yellow green in fall and are dull rather than shiny. It is fairly common and easy to find because it often forms very large mats.

Juniper haircap moss plants (Polytrichum juniperinum) look like tiny green starbursts. This moss grows on soil and is also very common in this area. I see them just about everywhere I go. Wet or dry, they always seem to look the same, even though many mosses change their appearance when they dry out.

When young the female spore capsule (sporangium) of juniper haircap moss is covered by a cap called a calyptra, which protects the spore capsule and the spores within. It is very hairy, and this is what gives this moss part of its common name. Eventually, as the capsule ages it moves from a semi vertical to a more horizontal position before the calyptra falls off.  The spore capsule continues to ripen and when the time is right it will open and release the spores. I’m guessing that at this stage the capsule is about the same diameter as a piece of cooked spaghetti. When it’s time to release the spores the end cap (operculum) of the now reddish brown, 4 cornered but not square spore capsule will fall off and the spores will be borne on the wind.

I don’t see splash cups on juniper haircap moss very often in this area but these plants had some of last season’s cups on them. Mosses in the Polytrichum genus have male and female reproductive organs on separate plants, so when you see these little cups you know you’ve found a male plant that is ready to reproduce, or already has. The male moss produces sperm in these splash cups and when a raindrop falls into the cup the sperm is splashed out. If there is enough rain water to swim in, the sperm will then swim to the female plant and fertilize the eggs. Each cup, about half the diameter of a pencil eraser, looks like a tiny flower with its rosettes of tiny leaves surrounding the reproductive parts.

Sometimes when you think you’re seeing moss you’re actually seeing a liverwort. The greater whipwort liverwort (Bazzania trilobata) lives happily on stones right along with mosses so you have to look carefully to be sure of what you’re seeing. A close look shows that it looks almost if it has been braided. Each leaf on this leafy liverwort is only about an eighth of an inch wide and has three triangular notches at its base. This is where the trilobata part of the scientific name comes from. It means “having three lobes.”

Tree skirt moss (Anomodon attenuates) does just what its name sounds like it would; it grows at the base of trees and makes them look like they’re wearing green stockings. It can also grow on soil or stone and can form extensive mats.

Tree skirt moss looks like it’s made up of tiny braided ropes when it’s dry. It is normally deep green but sometimes dryness can affect its color and shape. After a rain each tiny leaflet will pull away from the stem, giving the moss a slightly fluffier appearance than what we see here.

You might see dark green or purple spots on the bark of smooth barked trees like maple and beech and think you are seeing moss but this is another liverwort. There are about 800 species of frullania liverworts and many grow as epiphytes on the bark of trees and shrubs where the humidity is high. Epiphytic plants take nothing from the host plants they grow on, so this liverwort does no harm to trees. As it gets colder they turn color until they become a dark purple; almost black, so they are much more noticeable in winter than in summer when they’re green. Some can get fairly large but these examples were smaller than a tennis ball.

The tiny leaves of frullania liverworts are strung together like beads. Some frullania liverworts are said to be very fragrant but the few that I have remembered to smell didn’t seem to have any scent at all. This liverwort can cause something called woodcutter’s eczema. This eczema, called phytodermatitis (basically an itchy rash,) has been seen on loggers and others who regularly handle logs or cord wood with it on them. It doesn’t sound like anything serious and usually disappears in two or three weeks once the person stops handling logs with liverworts on them.

The name medusa moss (Hedwigia ciliata) comes from the way this moss looks like a bunch of tangled worms when it dries out. It is also called white tipped moss, because its branch tips are often bright white. This moss is fairly common and I find it mostly growing on stones in sunny spots. It always seems to be very happy and healthy.

Believe it or not this is the same Hedwigia ciliata moss we saw in the previous photo but this example was very dry. This is where the name “Medusa moss” comes from.

Stair-step moss (Hylocomium splendens) is a very beautiful moss that grows on stones and looks quite fragile, but I’ve seen it with icicles hanging from it so I can say with certainty that it’s a lot tougher than it looks. That is most likely why it grows as far north as the arctic tundra. It seems fairly rare here; this is the only example that I’ve seen.

When dry stair step moss has a slight satiny sheen to it, and that’s probably how it came by its other common name of glittering wood-moss. The name stair step moss comes from the way the new growth “steps up” off the midrib of the previous year’s branch.  Each year a new branch grows from the old and this growth habit allows stair step moss to grow up and over other mosses. It is said that you can tell the age of the moss by counting these steps, and from what I saw this branch that I found in 2014 would have been at least 5 years old.

White cushion moss (Leucobryum glaucum) gets its common name from the way it turns a whitish color when it dries out. When wet though, it can be dark green so it’s another moss that changes color.  This moss doesn’t reproduce by spores very often so it relies on vegetative reproduction. It grows on soil and turkeys and other animals that scratch at the soil help spread its pieces to other areas. I often see it scattered around some areas so it seems to happen regularly.

What this photo also shows are some fuzzy white growths on the white cushion moss that I’ve seen before but have never been able to identify. My gut feeling tells me that they have something to do with reproduction, but that’s little more than a guess. If you happen to know I’d love to hear from you. My moss books don’t mention them.

I found this pretty clump of what I think is flat glaze moss (Entodon cladorrhizans) growing on a dry ledge where soil had built up. This moss has shiny yellow green, overlapping leaves on stems that creep along whatever they grow on.  It also grows on rotting logs and tree trunk bases, mimicking the tree skirt moss we saw previously.

You can see some of the upright spore capsules (sporophytes) in this closer view of flat glaze moss. They are long and pointed when young and appear in late fall or winter. When mature they can be yellowish to reddish brown and will have a blunt, beaked end cap (operculum.) They are one of the things I used to help identify this moss, but I could still be wrong.

I hope you enjoyed meeting a few of the mosses I know. The next time you find yourself in a place like this with mosses all around I hope you’ll take the time to look a little closer. At this time of year anything green is welcome, and you might just see something beautiful enough to make you want to see more.

Moss grows where nothing else can grow. It grows on bricks. It grows on tree bark and roofing slate. It grows in the Arctic Circle and in the balmiest tropics; it also grows on the fur of sloths, on the backs of snails, on decaying human bones. It is a resurrection engine. A single clump of mosses can lie dormant and dry for forty years at a stretch, and then vault back again into life with a mere soaking of water. ~Elizabeth Gilbert

Change Comes to Beaver Brook

I haven’t been to the Beaver Brook natural area in Keene for a while so last weekend I decided take a walk up the old abandoned road. This road was gated when a new highway was built in the 1970s, but my father and I used to drive over it to visit relatives when I was a boy.  Back then the road went all the way to the state capital in Concord and beyond, but the new highway blocked it off and it has been a dead end ever since. At what is now the end of the road is a waterfall called Beaver Brook Falls and I thought I’d go see how much water was flowing over it. We’ve had a lot of a rain this year.

The old road follows along beside Beaver Brook and was originally built to access a sawmill which was built on the brook in 1736. In 1735 100 acres of “middling good land” and 25 pounds cash was offered to anyone who could build a sawmill capable of furnishing lumber to the settlement of Upper Ashuelot, which is now called Keene. Without a sawmill you lived in a log cabin, so they were often built before anything else in early New England settlements. The headwaters of Beaver Brook are in Gilsum, New Hampshire, north of Keene.

Tall blue lettuce (Lactuca biennis) grows prolifically here and is one of the first plants I notice at this time of year because it towers above everything else. The one growing up past the top of this photo must have been 8 feet tall. These plants usually end up with powdery mildew by the end of summer and this year they all seem to have it here. I was a bit surprised to see it though because this summer hasn’t been all that humid. It could be that the closeness of Beaver Brook makes the air slightly more humid. It is also usually very still here, with little wind.

As I’ve said many times on this blog, fall starts at the forest floor and lady fern (Athyrium filix-femina) tells me that fall is in the air. This is the only fern that I know of with fronds that turn white in the fall.

If you aren’t sure that you have a lady fern by its fall color you can always look at its sporangia, which are where its spores are produced. They are found on the undersides of the leaves and look like rows of tiny black eggs. The little clusters are usually tear drop shaped.

Hobblebush (Viburnum lantanoides,) one of our most beautiful native shrubs, was also whispering of fall.

Hobblebush berries start out green then turn to red before finally becoming deep purple black, so they’re at their middle stage right now.

A hickory tussock moth caterpillar (Lophocampa caryae) crawled on a goldenrod leaf. This black and white caterpillar can cause quite an itchy rash, from what I’ve read. The nettle like hairs can break off and stick in the skin and they are said to bother some people enough for them to be hospitalized, so it’s probably best to look and not touch this one.

When Indian pipes (Monotropa uniflora) turn their nodding flowers to the sky it means they’ve been pollinated and are ready to set seed. The plants will turn brown and become hard like wood, and finally the seed pods will split open and release the tiny seeds. They are dust like and are borne on the wind.

Orange crust fungus (Stereum complicatum) grew on the underside of a fallen branch. This small fungus has a smooth whitish underside with no pores. The complicatum part of the scientific name means “folded back on itself” and the above photo shows these examples just starting to fold. It also likes to grow on the logs of deciduous trees. It can be seen from quite a distance because of its bright color.

Ledges show how the road was blasted through the solid bedrock in the 1700s. The holes were all drilled by hand using star drills and there are still five sided holes to be seen in some of the boulders. Once the hole was drilled they filled it with black powder, lit the fuse and I would imagine ran as fast as they could run. There are interesting things to see here among these ledges, including blood red garnets, milky quartz crystals, many different lichens and mosses, and veins of feldspar.

It’s worth taking a close look at the ledges. In the right light the spore producing fruiting bodies (Apothecia) of smoky eye boulder lichens (Porpidia albocaerulescens) turn a beautiful blue. It happens because of a light reflecting, thin coating of wax that covers each one. In different light they can appear black, gray or whitish but in this light they glow different shades of blue and are as beautiful as jewels.

Another beautiful thing that grows on stone here is rose moss (Rhodobryum roseum.) Each little rosette of leaves looks like a tiny flower, and that’s how it comes by its common name. Rose moss is a good indicator of limestone in the soil so it’s wise to look for other lime loving plants in the area when it is found. This is a relatively rare moss in my experience; this is the only place I’ve ever found it.

One of the reasons I came here on this day was to get photos of purple flowering raspberry fruit (Rubus odoratus,) but I was surprised to see several plants still blooming. This plant is in the rose family and the 2 inch wide flowers might look like a rose at first glance, but one look at its large, maple like leaves will show that it isn’t. Flowering raspberry has no thorns like roses or raspberries but Japanese beetles love it just as much as roses and it’s common to see the large leaves looking like they’ve been shot full of holes. The plants are a little fussy about where they grow but they will thrive under the right conditions, as they once did here.

The fruit of purple flowering raspberry looks like a large raspberry. The plant is closely related to thimbleberry (Rubus parviflorus) and gets its common name from its fruit. I’ve never eaten one but some say that they’re close to tasteless and others say they taste like dried raspberries. The plant is unreliable as a source of berries though; I’ve seen many clusters with no fruit at all and others that had 5 or 6 flowers bearing only a single berry. Native Americans had over 100 uses for this plant, both as food and medicine.

Chances are you don’t see anything wrong with this view of the old road but I was appalled when I saw it. Thousands of wildflowers used to grow right over the road almost to the yellow lines on each side. There was a narrow, 2 person wide path through here last time I came, but now the city workers have come in and plowed all of the plants away. Without even having to think about it I could list over a hundred different species of plants that grew here and were plowed up.

Here is the view from where they finally stopped plowing up the plants. You can see how far they grew into the road in this spot but this doesn’t accurately show how it used to be because this is pretty much the end of the road just above Beaver brook falls, and few ever walked here. The plants didn’t grow quite so far out toward the yellow lines where people regularly walked.

And here is what is left of the plants; decades of growth just rolled off to the side like so much worn out carpet. Just think; many of the growing things at the beginning of this post and hundreds more like them just kicked off to the side. You would think before doing something like this that they would call in a botanist or a naturalist, or at the very least buy a wildflower guide so they knew what they were destroying but instead they just hack away, most likely thinking all the while what a wonderful thing they’re doing, cleaning up such a mess.

They’ve peeled the road right back to the white fog line at the edge of the pavement. This is what happens when those who don’t know are put in charge of those who don’t care; nature suffers every single time. What these people don’t seem to realize is that they’ve just plowed away the whole reason that most people came here. I’ve talked to many people while I’ve been here and most came to see what happens when nature is allowed to take back something that we had abandoned. You marveled at the history before you; the charm of the place was in the grasses and wildflowers growing out of the cracks in the pavement, not a road scoured down to just built condition. New Hampshire Public Radio even did a story about the place precisely because it was untouched. The very thing that drew so many people to the place has now been destroyed, and it will be decades before it ever gets back to the way it was. I certainly won’t be here to see it.

A lot of people also come here to see Beaver Brook Falls, but to get a clear view of them you have to climb/ slide / fall down a very steep embankment and then climb over large boulders. It’s becoming more dangerous all the time and now younger people are about the only ones who dare do it. If you broke an ankle or leg down here it would take some serious work and several strong men to get you out, but Instead of cutting the brush that blocks the view of the falls from the road so people don’t have to make such a dangerous climb down to the brook to see the falls, the city would rather spend their money plowing up all the wildflowers.

This is the view as you’re leaving. Where the road is narrower is where they left a few yards of growth at the start of the road, but I wouldn’t count on it being this way the next time I come here. You might say “Big deal, who cares about a few old weeds?” But what grows in those unplowed strips of vegetation includes blue stemmed goldenrod; I’ve never seen it anywhere else. White wood sorrel; I’ve seen it in one other place. Field horsetails; I’ve seen them in one other place. Plantain leaved sedge; I’ve never seen it anywhere else. Yellow feather moss; I’ve never seen it anywhere else. Thimbleweed; I’ve never seen it anywhere else. After wandering through the destruction for as long as I could stand it I had to go into the woods for a while because, as author David Mitchell said: Trees are always a relief, after people.

Lord, what fools these mortals be! ~William Shakespeare

Things I’ve Seen

It has cooled off now but “cool” compared to the near 70 degrees of last week means 40s and 50s this week, and that’s still warm for March first. That means a lot of snow has melted and that has turned our normally placid streams into raging rapids, as this shot of Beaver brook shows. No beaver in its right mind would be swimming in that.

But they do eat trees all winter long if the ice of their pond doesn’t freeze completely. This beech tree was still being visited each night well into February. The hole in the ice must have closed up because they haven’t been here for a while.

A beaver’s teeth grow continuously so they have to be chewing on something all the time. In this instance a beech tree was chosen, but they’ll chew on just about any species of tree. I’ve even seen them tackle  elms, which is one of the toughest woods I know of. Their incisor teeth wear away faster on the rear surface than the front, so a chisel edge is created by the uneven wear.

The chisel edged teeth of a beaver can leave a sapling looking like it has been cut by steel loppers. Native Americans called beavers “Little People,” and are said to have greatly respected them. They used beavers for food, medicine and clothing and Native children of some tribes would offer any teeth that they had lost to the beavers for good luck.

I decided to pay a visit to the one small patch of rose moss (Rhodobryum roseum) that I know of. Rose moss is a very beautiful moss; each little rosette of leaves looks like a tiny flower, and that’s how it comes by its common name. Rose moss is a good indicator of limestone in the soil so it’s wise to look for other lime loving plants in the area when it is found. This is a relatively rare moss in my experience.

Not rare at all but still very beautiful are the smoky eye boulder lichens (Porpidia albocaerulescens) that I find growing on stone. The golden body of the lichen studded with blue apothecia could almost pass for a piece of jewelry. The blue color is caused by the way light reflects off a waxy coating on the fruiting bodies (Apothecia,) which is very similar to the “bloom” found on plums, blueberries, and grapes. It’s as if pieces of the sky had been sprinkled on the stones when the light is right, but the apothecia can also appear black or gray depending on which direction the light happens to be coming from.

One morning as I was getting ready for work I saw something move out of the corner of my eye. It was a tiny spider with big eyes. It sat very still, watching me as I fumbled with my camera, trying to turn on the on board LED light. I finally got it and that’s what caused the shadows in this photo.

It was a furry little thing. And it was little; it could have easily hidden behind a pea. It wasn’t frightened by the camera and remained still, seemingly very interested in what I was doing. It had plenty of eyes to watch me with. (They have 8 of them.)

I got a blurry photo of its back as it scurried away, and the markings lead me to believe that this was a female tan jumping spider called Platycryptus undatus. I’ve read that they live on vertical surfaces like tree trunks, fence posts, and outer walls so what she was doing on my horizontal table is a mystery. I’ve also read that they are very curious about people and can be quite friendly when they’re handled gently. I didn’t see this one jump but they do, up to 5 times their own body length. Which isn’t far when you consider that this one was half the size of a pea. I haven’t seen her since that morning.

There are still quite a few oriental bittersweet berries that the birds haven’t eaten and that’s a good thing, because birds help this very invasive alien plant get around. This example didn’t look very tasty.

Oriental bittersweet isn’t well liked by those who know it, and the above photo shows one reason why. The vines are as strong as wire and when one wraps itself around a tree it will not break or give, so as the tree grows the vine cuts into it and strangles it. The tendrils on the left are from another vine; a grape.

A stick figure walked across an oak leaf.

I’ve never seen a firefly light up in winter but I have seen the winter dark firefly (Ellychnia corrusca.) It is commonly seen on snow and tree trunks  according to Bugguide.net, and can be a pest in sap buckets in the spring because they like sap and will drink from wounds in trees. They like to sun themselves on the sunny side of trees or buildings, but this one was looking for a crevice in the bark of an oak to hide in. It looked at several before it found one that was to its liking.

I saw this gypsy moth (Lymantria dispar) egg case on a tree. Gypsy moths were first introduced from Europe to Massachusetts in 1869, to breed with the silkworm moth to produce a tougher silkworm. Naturally, it escaped and has become one of the chief defoliators of deciduous trees and conifers in the eastern United States. Each egg mass can contain 100-1000 eggs and should be destroyed when found. It looked like a bird had been at this egg case.

I see beard lichens (Usnea) almost always growing on tree branches but occasionally they grow on tree trunks; especially white pines (Pinus strobus.) Even rarer are those that grow on stone. I see maybe 1 out of 100 growing on stone. If you see beard lichens in your area rejoice, because they are very fussy about pollutants and will only grow where the air is clean and of high quality. The air here must be very good because I see these bushy little lichens everywhere, even growing on wooden fences. Lichens in the Usnea genus contain usnic acid and have antiseptic / antibiotic properties. They have been used since ancient times throughout the world to heal wounds.

I’ve spent years trying to identify some lichens and I might have to wait that long before I know this one’s name. I’ve searched lichen books and online and can’t find any lichens that look like it. Blue and yellow doesn’t seem to be a very common color combination among lichens. This example grew on maple tree bark.

The book Lichens of North America says the fruiting bodies (apothecia) of the mealy rim-lichen (Lecanora strobilina) are flat to convex and a waxy yellowish color. These look more orange but I’m sure they must vary some. They grow on bark and wood of many kinds in full sunlight and the apothecia are very small at about .03 inches.  I think this is one of those lichens that prefers winter for producing spores. I’m suddenly seeing it everywhere.

I know disc lichens because of rock disc lichens (Buellia geophila) but the problem was the example in the above phot was growing on tree bark. For that reason I think it must be a cousin of the rock disc called simply disc lichen (Buellia erubescens.) The body of the disc lichen is gray, grayish white to ivory, dull, and smooth. Its fruiting bodies are convex and black, and are called discs. It grows on the bark of oaks, pines, and junipers, or other trees with bark of low pH. I found this example growing on an oak.

This is just a small feather in the mud but it was pristine and very downy, like it came from a bird’s breast.  It’s a beautiful thing.

Leisure is a form of silence, not noiselessness. It is the silence of contemplation such as occurs when we let our minds rest on a rosebud, a child at play, a Divine mystery, or a waterfall. ~Fulton J. Sheen

Mosses

One of the things I like about this time of year is how you can see so much further into the forest once the shrubs that make up the undergrowth have lost their leaves. This means that things that were hidden all summer like mosses suddenly become very visible. I was surprised to find that I could see so far up Brickyard Brook in Winchester recently. The water was very low and every stone was covered in moss. This is odd since not that long ago water covered most of the stones. Can mosses really grow that fast, or were they there underwater the whole time, I wondered. There are aquatic mosses and one called common water moss (Fontinalis  antipyretica) was recently found to be growing at 1000 foot depths in Yellowstone Lake, near a geo-thermal vent.

Mosses don’t have roots but on dry land they soak up rain water like a sponge and release it slowly over time. Other water loving plants like this dog lichen (Peltigera membranacea) take advantage of that and grow among them so they won’t dry out. This lichen was moist and pliable, even though we’ve been in a drought for months. Mosses also benefit the ecosystem in many other ways.  Bryologist Dr. Robin Wall Kimmerer says that “One gram of moss from the forest floor, a piece about the size of a muffin, would harbor 150,000 protozoa, 132,000 tardigrades, 3,000 springtails, 800 rotifers, 500 nematodes, 400 mites, and 200 fly larvae.”

The name medusa moss (Hedwigia ciliata) comes from the way this moss looks like a bunch of tangled worms when it dries out. It is also called white tipped moss, for obvious reasons. This moss is fairly common and I find it mostly growing on stones in sunny spots. It always seems to be very happy and healthy.

I think this moss must be rambling tail moss (Anomodon viticulosus) because of its long length and its habit of growing out away from the tree’s trunk. I think it is too long to be tree skirt moss (Anomodon attenuates.)

The main stems of rambling tail-moss are said to be creeping with blunt ends like a paintbrush, and they arch upward when dry like a hook. Those attributes and their yellow green color are what lead me to think that this example is Anomodon viticulosus, but I could be wrong. You really need a microscope to be sure when there are several mosses that look so much alike.

Apple moss (Bartramia pomiformis) doesn’t look like many other mosses so it’s relatively easy to identify. Its reproduction begins in the late fall and immature spore capsules (sporophytes) appear by late winter. When the warm rains of spring arrive the straight, toothpick like sporophytes swell at their tips and form tiny globes that always look like pearls to me, but someone thought they looked like apples and the name stuck.

Though they’re orange on this example sometimes the spore capsules do turn red as they age, so I guess the name apple moss is appropriate.

Broom moss (Dicranum scoparium) gets its common name from the way the leaves all point in the same general direction, making it look as if it had been swept by a broom. It’s a fairly common moss that grows in large tufts or mats on logs and tree bases, soil or stone.

Delicate fern moss (Thuidium delicatulum) changes from deep green to lime green when it gets cold and becomes one of the more visible mosses. It grows in soil in shaded spots and I find it in my lawn each fall. It will also grow on the base of trees and on logs and boulders, where it can form quite dense mats. Orchid growers use this moss in orchid cultivation.

Greater whipwort (Bazzania trilobata) grows right alongside mosses but it’s a liverwort. A close look shows that it looks almost if it has been braided. Each leaf on this leafy liverwort is only about an eighth of an inch wide and has three triangular notches at its base. This is where the trilobata part of the scientific name comes from. It means “having three lobes.”

Stair-step moss (Hylocomium splendens) is a very beautiful moss that grows on stones and looks quite fragile, but I’ve seen it with icicles hanging from it so I can say with certainty that it’s a lot tougher than it looks. That is most likely why it grows as far north as the arctic tundra. It seems fairly rare here; this is the only place that I’ve seen it.

When dry stair step moss has a slight satiny sheen to it, and that’s probably how it came by its other common name of glittering wood-moss. Its common name comes from the way the new growth “steps up” off the midrib of the previous year’s branch.  Each year a new branch grows from the old and this growth habit allows stair step moss to grow up and over other mosses. It is said that you can tell the age of the moss by counting these steps, and from what I saw this branch would have been at least 5 years old.

This is the first time that big red stem moss (Pleurozium schreberi) has appeared on this blog because, though I’ve seen it for years I have only just learned its name. It’s a very common moss that I often see growing in very large mats, sometimes even overrunning other mosses. I finally learned the name of this one by reading The Saratoga Woods and Waterways Blog. If you love nature and aren’t reading this blog you’re doing yourself a disservice.

It should be obvious how big red stem comes by its common name but I don’t see any red, and neither does my color finding software. I’ve looked through two moss books and countless photos on line though, and all examples of big red stem look like this example. That makes me wonder if its stem isn’t red for part of the time. Mosses do change color.

Rose moss (Rhodobryum roseum) is a very beautiful moss and one of my favorites. Each little rosette of leaves looks like a tiny flower, and that’s how it comes by its common name. Rose moss is a good indicator of limestone in the soil so it’s wise to look for other lime loving plants in the area when it is found. This is a relatively rare moss in my experience. I know of only one place to find it.

Moss grows where nothing else can grow. It grows on bricks. It grows on tree bark and roofing slate. It grows in the Arctic Circle and in the balmiest tropics; it also grows on the fur of sloths, on the backs of snails, on decaying human bones. It is a resurrection engine. A single clump of mosses can lie dormant and dry for forty years at a stretch, and then vault back again into life with a mere soaking of water.

Things I’ve Seen

I found what was left of a daylily seed pod at work one day. An insect had eaten all of the soft tissue and left the tougher veins, creating a work of art in the process. Sometimes I have to wonder if creating works of art aren’t their primary purpose; I’ve seen some amazing things done by insects. The engraver beetle for instance, creates some beautiful and intricate calligraphy on tree branches.

I had to tangle with a Japanese barberry (Berberis thunbergii) at work recently. The plant was quite old and some stems were bigger around than my thumb, which is unusual. Usually they are no bigger than a pencil but in this case the large size made the chrome yellow inner bark much easier to see. Barberry is the only shrub I know of with such vibrant color under its bark.

When Japanese barberry bark is injured the bright yellow color of the inner bark is easily seen. I decided to whittle the bark off a piece of stem to see what it would look like. When I put it against my black coat to take a photo it seemed to glow, so bright was the color, and in the photo it almost doesn’t look real. Not surprisingly, a bright yellow dye can be made from chipped barberry stems and roots and apparently this is true of any barberry, not just the Japanese variety.

If the inner bark doesn’t convince you that you have a barberry the fruit and thorns (actually spines) will. These small red berries are what make the Japanese variety so invasive. I’ve seen impenetrable thickets of it in the woods that not only crowd out native plants but also prevent all but the smallest animals getting through. Its sharp spines will tell you which variety of barberry you have. European barberry (Berberis vulgaris) and American barberry (Berberis canadensis) both have clusters of 3 or more spines but since American barberry doesn’t grow in New England it comes down to European or Japanese here, and only Japanese barberry (Berberis thunbergii) has single spines.

Something I’ve never noticed before is animals eating birch polypores (Piptoporus betulinus,) but this year I’m seeing half eaten ones everywhere. Scientists have found that this mushroom is effective in treating intestinal parasites and I wonder if animals eat them for that reason or simply as food. Since chipmunks aren’t active during the winter it would probably be squirrels, deer or porcupines. I read that these fungi smelled like green apples and, though I’m not sure what green apples smell like the mushroom does have a strong but pleasant scent.

I found this starburst scar on a maple trunk and can’t imagine what made it. The way the bark has turned platy reminds me of target canker on maples, but that isn’t shaped the same. It could have simply been caused by a boy with a pocket knife, but I don’t suppose that I’ll ever know.

This bark deformity I know well, unfortunately. Beech bark disease is caused by beech scale insects (Cryptococcus fagisuga) that pierce the bark and leave a wound. If the spores from either of two fungi, called Neonectria faginata and Neonectria ditissima, find the wound and grow, cankers form. These cankers are what look like blisters on the bark of beech trees, as can be seen in the above photo. The disease originally came from Europe and the first case in the United States was reported in 1929 in Massachusetts. By 2004, the disease had spread as far west as Michigan and as far south as western North Carolina. There is no cure and infected trees will ultimately die.

I start watching buds closely at this time of year and one of those I watch are the naked buds of hobblebush (Viburnum alnifolium.) They are naked because they have no bud scales to protect them but they make up for the lack by being covered with a multitude of fine hairs. In this photo the flower bud is in between two leaf buds that stand up like wings. In about mid-May the flower bud will become one of our most beautiful native viburnum flowers.  This understory shrub gets its name from the way its sprawling stems can trip up or “hobble” a horse, but it isn’t just horses that get hobbled; I’ve gotten my feet tangled in it a few times. I’m guessing that the white hairs seen in the photo are from a deer, so apparently the stems don’t hobble them.

Hobblebush and striped maple (Acer pensylvanicum) often grow side by side. Deer had eaten the buds off many of the striped maples that were growing near the hobblebush in the previous photo, but they missed this one. Striped maple buds are on my list of things to watch at this time of year because when the red or pink bud scales open and the leaves emerge they are easily one of the most beautiful things in the forest.

Just to give you a little preview of why my pulse quickens in spring, here is a photo from last April of striped maple buds after they had just opened. The chance of seeing beauty like this again is what gives me spring fever.

But not so fast; there are a few things that nature has to take care of first, like this ice fall that I saw in the woods the other day. It was big.

The combination of a mild winter and growing near a stone chimney kept this motherwort plant (Leonurus cardiaca) green through the winter. Motherwort is originally from Europe where it has been used medicinally for centuries. It is said to calm the heart and nerves as the cardiaca part of its scientific name implies. The ancient Greeks gave it to pregnant women, and that’s how it comes by its common name. Colonists brought it to North America, which is a sign that it was very highly regarded.

The lack of snow this winter has meant rough times for our mosses, but rose moss (Rhodobryum roseum) is still pretty even when it’s as dry as paper. Each rosette of leaves looks like a tiny flower, and that’s how it comes by its common name. It’s one of the most beautiful of all the mosses, in my opinion. Even when dry it sparkles as if with an inner light.

Mosses

One of the things that I like about this time of year is how the all the mosses are suddenly so easy to see, so this is when I go visiting them. Mosses call to me and make me want to know more about what I’m seeing, so I’ve been studying them for a few years. If a scene like the one in the above photo gets your blood pumping, this post is for you. I’ve been both wanting to do it and dreading it for a while now. If you’ve ever tried to identify mosses I’m sure you understand.

Delicate fern moss (Thuidium delicatulum) changes from deep green to lime green when it gets cold and then eventually becomes one of the more visible mosses. It grows in soil in shaded spots and I find it in my lawn each fall. It will also grow on the base of trees and on logs and boulders. It forms quite dense mats as can be seen in the above photo. Orchid growers use this moss in orchid cultivation.

This moss growing on the base of a tree almost had me fooled into thinking that it was tree skirt moss (Anomodon attenuates) but a closer look has me believing that it must be rambling tail moss (Anomodon viticulosus) instead. This moss is too long to be tree skirt moss, I think, and its habit of growing out away from the trunk isn’t right for that moss either. The main stems of rambling tail-moss are said to be creeping with blunt ends like a paintbrush, and they arch upward when dry like a hook. That and their yellow green color are what lead me to choose Anomodon viticulosus, but I could be wrong.

Common haircap moss (Polytrichum commune) is one of the most common and also one of the largest mosses in this area, and that makes them easy to identify and study. I find them growing in soil just about everywhere I go.

Last year I found a blue haircap moss spore capsule but this year the best I could do was salmon pink. These capsules are rectangular in shape with corners and often sunken sides as the photo shows. The light colored ring on its end is called a peristome and has 64 tiny teeth around its inside diameter, which is measured in micrometers. The teeth can’t be seen in this photo and neither can the cap, called a calyptra, which protects the spores and in this instance is hairy, and which is what gives this moss its common name. When the spores are ready to be released the calyptra falls off and the spores are borne on the wind.

Red penny moss (Rhizomnium punctatum) is a very small but leafy moss that was renamed from Mnium punctatum. I find it growing in deep shade in the soaking wet soil of seeps. It is a forest moss but only in very wet areas that don’t easily allow kneeling for a photo.

On male red penny moss plants in the center of the leaf rosettes are what look like tiny blackberries. These are actually the antheridia, which are where the sperm is produced. When mature the sperm will wait for a rainy day and then will swim to a female plant. Once fertilized the female plant will produce spores and send them off on the wind.

It looks like apple mosses (Bartramia pomiformis) are growing white whiskers for winter. Do they always do this, I wonder? Maybe I’ve just never noticed, but since this is one of the easier to see mosses I don’t know how I could have missed it. I’ve looked in my moss books and on line and can’t find another example with white tips, but on this day I saw many. This moss gets its common name from its spherical spore capsules that some say look like tiny green apples.

In her book Gathering Moss author Robin Wall Kimmerer tells of an experiment where chipmunks were coaxed into running over some sticky paper. When the paper was examined it was found to have thousands of moss spores stuck to it, so if you’ve ever wondered how mosses get 100 feet up in the tree tops thank a chipmunk, because the spores stick to their feet. And squirrel’s feet too, I’m guessing.  Of course, wind and rain also carry spores so rodents don’t have to do all the work. The above photo is of tiny green moss islands I found on the trunk of a tree, and I think it shows the spores just becoming recognizable plants. I wish I’d seen that lichen on the right with rose colored apothecia when I took this photo. It’s a beauty.

I think the moss islands in the previous photo will turn into something like this clump of crispy tuft moss (Ulota crispa.) This moss is very common on tree trunks in these parts and I see it all the time. When dry its leaves tighten and curl.  This clump was about an inch across.

Some mosses are so animal like they make you want to reach out and pet them. This broom moss (Dicranum scoparium) is one of those that I had to touch before I left it. This moss grows on stone, wood or soil in sunnier places and it’s common here.

Another very beautiful moss is rose moss (Rhodobryum roseum,) shown here growing against the dark shine of a dog lichen (Peltigera membranacea) on a boulder. Each little rosette of leaves looks like a tiny flower, and that’s how it comes by its common name. Rose moss is a good indicator of limestone in the soil so it’s wise to look for other lime loving plants when it is found. Many native orchids for instance, fall into that category.

The name medusa moss (Hedwigia ciliata) comes from the way this moss looks like a bunch of tangled worms when it dries out. It is also called white tipped moss, for obvious reasons. This moss is fairly common and I find it mostly growing on stones in sunny spots. It always seems to be very happy and healthy.

This is the first time this moss has appeared on this blog because I’ve only just found it. I think it might be a moss called river foxtail moss (Brachythecium rivulare) which is said to have a whitish cast.  I found it growing in shade on a stone shelf where it was watered by constantly dripping ground water; exactly the habitat that river foxtail moss likes.

This moss was growing right beside the one in the previous photo but even though I tried several times it was simply too small to get a sharp photo of. Instead over and over the camera focused on the tiny water droplets that decorated it like Christmas ornaments, so that’s what I’ll show here. Everything seen in this photo would easily fit on a penny (.75 inches.)

Pleasure is spread through the earth in stray gifts to be claimed by whoever shall find them. ~William Wordsworth
