Mosses

It’s a shame how some people think winter is a ‘dead time’ when there is nothing to see outside. I challenge anyone to find a scene more alive than this one at any time of year, or more beautiful. This, to me, is a little slice of paradise. But it is also a place of mystery; on this little hill grow possibly hundreds of species of mosses and I can’t know them all, but I can know a few and each year I try to learn at least one more new one. I hope you’re interested enough to meet the ones I do know.

One of my favorite mosses is the delicate fern moss (Thuidium delicatulum) because though it turns lime green in cold weather colorblindness makes it look bright orange to me, and what could be better than orange moss? It grows in my lawn so it’s very easy to find. It’s very pretty, especially in the fall, and I wouldn’t really mind if the lawn went away and the moss took over.

Many mosses will grow on wood, stone or soil and delicate fern moss is one of them. It’s is a beautiful little thing that isn’t as delicate as its name implies, but it certainly is fern like. The leaves of this moss are often dull rather than shiny. It is fairly common and easy to find because it often forms very large mats. Orchid growers use this moss in orchid cultivation.

Brocade Moss (Hypnum imponens) is very shiny and sometimes has an orange brown color. It often forms very large mats as it did here, covering this entire log.

Brocade moss gets its common name from the way it looks as if it has been embroidered on whatever it happens to be growing on.  It is easily confused with knight’s plume moss (Ptilium crista-castrensis,) but the spore capsules on knights plume moss are elbow macaroni shaped and horizontal, while those of brocade moss are cylindrical and stand vertically.

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 as they are in this photo. 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.

White cushion moss (Leucobryum glaucum) can appear silvery, white, bluish green or grayish green but it always forms a thick cushion and stands out from the mosses that might surround it. It likes plenty of water and shade and grows on rotting logs or on stone when there is enough soil. It is probably the easiest of all the mosses to identify.

Apple moss (Bartramia pomiformis) doesn’t look like very 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.

Big red stem moss (Pleurozium schreberi) is a very common moss that I often see growing in very large mats, sometimes even overrunning other mosses. In fact I’ve never seen a moss grow as fast as this one. It should be obvious how big red stem comes by its common name but I don’t see any red. 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.

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 fluffy appearance.

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 it. You can’t see it in this photo because it has fallen off already but it is very hairy and this is what gives this moss part of its common name. Eventually as the capsule ages it moves from vertical to a more horizontal position and the calyptra falls off. The spore capsule continues to ripen after the calyptra comes off and when the time is right the beaked end cap or lid called the operculum will fall off and release the spores to the wind. As it ages the spore capsule changes from round to four cornered but not quite square, as seen here.

If your camera can do this, you’d better hang onto it because it’s a good one. I’ve gotten a useable shot of the end of a juniper haircap moss spore capsule exactly twice over too many tries to count. This photo shows it is still covered by a thin lid of tissue. What looks like notches around its perimeter are slots that fit over specialized teeth called peristome teeth at the mouth of the capsule. These teeth move with changes in humidity and spread in dry conditions to release the spores, which are taken by the wind. The spore capsule’s diameter at this stage is less than the diameter of a piece of uncooked spaghetti. I wish I had a microscope so I could get even closer.

Rose moss (Rhodobryum roseum,) grows on stone and is another of my favorites. This pretty little leafy 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. It forms dense mats and gets its common name from 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.

Blackish male organs produce sperm which will be splashed out of the center of the rose moss rosettes by rain drops, and when they land on female structures that produces egg cells, called archegonium, a drooping, pear shaped spore capsule (sporophytes) will grow. Rose moss also reproduces by horizontal underground stems so spore capsules are rare. This is why new clumps of this moss are so hard to find.

Another leafy moss which I have to hunt high and low for is the Appalachian penny moss (Rhizomnium appalachianum) but it’s worth it because it’s so pretty and unusual. Though some mosses like this one can resemble vascular plants, mosses have no xylem and phloem, or vascular tissue. This is why mosses are classified as Bryophytes; plants that have no roots, leaves, or stem. They also have no flowers or seeds and reproduce through spores. Since mosses have no roots they need to grow in areas with adequate moisture. This one grows in soil that was dripping wet.

This moss is easily confused with red penny moss (Rhizomnium punctatum) so you have to look at the stems. Only the stems of Appalachian penny moss will be hairy over their entire length as seen here.

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, and it doesn’t seem to be spreading.

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.

Any moss post I do usually has at least one unknown but I often delete them before you see them. I left this one in because I like its happy, curly appearance. Though it fills this photo it is the tiniest moss in this post at about 1/2 an inch across. It grew on tree bark.

I like to visit my friends the tree mosses (Climacium dendroides) every now and then but it’s getting harder to get to them. What was once a streamside trail has become a brushy maze that I had to weave my way through. They are cheery mosses that look like little palm trees, and they always glow with a beautiful inner light, so they’re worth the effort. By this stream is the only spot I’ve ever found them so they aren’t common here, but I was happy to see that they’ve spread quite well where they grow. They must not mind being under water for a time because their stream floods once or twice a year.

You’ll notice that many of the mosses shown here like rose moss and tree moss are hard to confuse with other mosses, but some like that little unknown moss could be any one of three or four different mosses. They can be very difficult to identify but I try to do it because I’m a nature nut. You don’t have to be a nature nut though; you can enjoy the beauty of these beings without knowing a single one of their names. When you see a scene like the one above you can simply go and sit with them for a bit, and just admire them. They’re a fascinating and important part of nature.

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

Beaver Brook

It was cloudy but warm last Saturday when I visited the Beaver Brook Natural Area in Keene. This is a nice walk on an old abandoned road that is only 5 minutes from the center of town by car, so quite a few people come here. I was pleased to see that there was little snow here on this day because it usually quickly turns to ice from all the foot traffic. As I said in my last post, it is very strange to drive from here where there is virtually no snow to my job a half hour away in Hancock, where there is plenty.

Beaver Brook was behaving itself despite all the rain and snow we’ve had. The last time I came here I would have been in water up to my neck if I’d been standing in this spot.

I have a lot of old friends here, like this plantain leaved sedge (Carex plantaginea.) This is the only place I’ve ever seen it so when I want to see how it changes as it grows I have to come here. There are also many other one-of-a-kinds I can visit while I’m here.

I like the crepe paper like leaves of this sedge.

The sun finally came out just a few hours later than the weather people said it would, and the golden light falling on the brook was beautiful. I dilly dallied for a while beside this pool, thinking how some might consider coming to such a place a waste of time or an attempt to escape reality, but this is not an escape from reality; it is an immersion in reality, because this is just about as real as it gets. And getting a good dose of reality is never a waste of time.

This is the only place I know of to find the beautiful rose moss (Rhodobryum roseum.) Each rosette of leaves is about the size of an aspirin and looks like a little flower, and that’s where its common name comes from. Rose moss likes limestone and it’s a good indicator of limestone in the soil or stone that it grows on, so it’s a good idea to look around for other lime loving plants if you find it. Many native orchids for instance, also like lime in the soil.

Another moss that I’ve only seen here is the stair-step moss (Hylocomium splendens,) which is also called glittering wood moss  possibly due to its satiny sheen when dry. Though it looks quite fragile I’ve seen it with icicles hanging from it many times, and it grows north even into the Arctic tundra. The stair step part of the name comes from the way new growth “steps up” off the midrib of the previous year’s growth. You can’t see it in this photo but it’s a fun thing to look for if you find this moss.

Unlike the rarer mosses we’ve just seen juniper haircap moss (Polytrichum juniperinum) grows just about everywhere, but that doesn’t mean it is any less interesting than the others.

When young the female spore capsule (Sporangium) of juniper haircap moss is covered by a cap called a calyptra which protects it. You can’t see it in this photo but it is very hairy and this is what gives this moss part of its common name. Eventually as the capsule ages it moves from vertical to a more horizontal position and the calyptra falls off. The spore capsule continues to ripen after the calyptra comes off and when the time is right the beaked end cap or lid called the operculum will fall off and release the spores to the wind. As it ages the spore capsule changes from round to four cornered but not quite square, as seen here.

This is a look at the business end of the spore capsule, which is still covered by a thin lid of tissue. What looks like notches around its perimeter are slots that fit over specialized teeth called peristome teeth at the mouth of the capsule. These teeth move with changes in humidity and spread in dry conditions to release the spores, which are taken by the wind. The spore capsule’s diameter at this stage is less than the diameter of a piece of uncooked spaghetti. I’d bet that I’ve probably tried a thousand times over the years to get this shot and this is the only time I’ve succeeded.  I wish I had a microscope so I could get even closer.

Here was another moss that grew all mixed in with a liverwort. It was hard to tell exactly what it was but its sporangium were covered by white calyptra that looked like a swarm of tiny insects with white wings.

Here is a shot of one of the spore capsules from the moss in the previous photo. The spore capsules have a white (when dry) 2 part calyptra that doesn’t appear to be hairy, and I haven’t been able to identify it. I have a feeling it is another moss in the Polytrichum family but I don’t know that for sure. Sporangium means “spore vessel” in Latin, and of course that’s exactly what it is. Note the long beaked lid at the end of the capsule, which is its operculum.

The liverwort that was mixed in with the moss in the previous photos was the greater whipwort liverwort (Bazzania trilobata.) It lives happily on stones right along with mosses so you have to look closely to be sure what it is you’re looking at. This pretty liverwort looks almost like it has been braided and always reminds me of a nest full of centipedes.

Each greater whipwort leaf is about an eighth of an inch wide and has three triangular notches at its base. This is where the trilobata part of its scientific name comes from. It means “having three lobes.” You might notice though, that some have more than three.

There was a good bit of ice on the roadside ledges but it was rotten and falling so I didn’t get too close.

Drill marks in the stone of the ledges tells the history of this place. This road was one of the first laid out in the town of Keene, built to reach the first sawmill. If you didn’t have a sawmill in town in those days you had a dirt floor. Or one made of logs, which was probably worse than dirt.

It turned out to be a beautiful and relatively warm day. The lack of snow on the old abandoned road made walking a pleasure. I’ve seen this natural canyon with so much snow in it I had to turn back.

The yellow lines are still here on the old road, but since nobody has driven here since about 1970 they really aren’t needed.

One of the best examples of a healed frost crack that I know of can be seen here in this golden birch. Sun warming the bark in winter can cause a tree’s wood to expand. If nighttime temperatures fall into the bitterly cold range the bark can cool and contract rapidly, but when the wood beneath the bark doesn’t cool as quickly as the bark the stress on the bark can cause it to crack. On cold winter nights you can often hear what sounds like rifle shots in the woods, but the sounds are really coming from cracking trees. They can be quite loud and will often echo through a forest.

The spot where this yellow jelly fungus (Tremella mesenterica) grew was heavily shaded so I had to use my camera’s onboard LED light to get a shot of it. I was surprised when I saw the photo because you could clearly see the shiny and dull, matte finish surfaces on the fungus. I’ve read that the fungus produces spores only on its shiny side, but in previous photos I’ve taken the entire thing always looked shiny. This is the first time I’ve ever seen the two surfaces in a photo so I’m quite happy to have solved another riddle, even though there are always hundreds more just around the next bend when you’re involved in nature study.

If you come upon a white spot on a tree that looks like it has been inscribed with ancient runes you are probably seeing a script lichen. This common script lichen (Graphis scripta) was bold and easy to see. The dark lines are its apothecia, where its spores are produced, and the gray color is its body, or thallus. If you happen to be a lichen there is nothing more important than continuation of the species through spore production, and script lichens produce plenty in winter.

There is a great waterfall here but unfortunately you have to just about break your neck to get to it, so since I wasn’t interested in doing so here’s a shot of it from a few years back. Height estimates vary but I’m guessing about 30-40 feet, and it was roaring on this day. Just think; history lessons, plants, ferns, lichens, mosses, fungi, liverworts, a waterfall and a brook that sings to you all along the way. Where else can a nature lover find all of these things in one walk? Nowhere else that I know of, and that’s why I come here again and again. I do hope you aren’t getting bored from seeing it so much.

To taste life, so true and real. Sweet serenity. ~Jonathan Lamas

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.
