Exploring Along Beaver Brook

Toward the end of November I decided to take a walk up the old abandoned road that leads through the Beaver Brook natural area in Keene. I hadn’t been there in a while and since I had just tangled with Covid I thought the slight gradient of the old road would let me gently test my lungs and make sure they were still working as they should. Surprisingly I didn’t get winded at all; good news I thought, considering all I had heard about Covid.

I saw many beautiful things there that day but I would have been happy just seeing the mosses. They always seem so much greener and more vibrant in colder weather.

The brook was rushing along, not quite as high as I had imagined it would be but still with a bit of a roar to it. It has many voices, this little brook. In summer it becomes tame and moves slowly, giggling and chuckling shyly as it spills over the rocks in its bed. In winter it often becomes nearly mute, its voice muffled by a covering of thick ice. It can still be heard, but as if from a distance. In spring and fall, due to snow melt or excessive rain it swells up and shouts, sometimes with a deafening roar. Only one thing about it never changes, and that is its beauty.

There are a few pretty views along the brook and this is one of my favorites. I hadn’t gone there that day with a blog post in mind but I had a cell phone camera and the small Olympus I use for macro photos and in the end, I was glad I had brought them.

Of course, I had to stop and see my old friend the smoky eye boulder lichen that lives here because it is a beautiful thing. Both the way the light falls on it and the color of the thallus or body of the lichen make it stand out from other examples I’ve seen. Why it has this golden, orangey brown color I don’t know, and I also don’t know why the fruiting bodies always seem so blue or lavender when they are usually gray. It has to be the special way the light falls on it in this particular spot. Seeing it again is always like finding a jewel.

The squiggly black apothecia have appeared on the script lichens, as they always seem to do in the cold weather. If you look at them extremely closely, they look like the body of the lichen has been torn or cut open, and they erupt from it rather than sitting on it. But whatever happens when they appear, they leave no trace when they disappear. If you come here in warmer months all you will find are the white / gray body of these lichens, like spots on the tree’s bark.

I stopped at what I call the boulder fall. I’ve found mosses here that I’ve never seen anywhere else.

And one of those mosses is the pretty little rose moss. This moss likes limestone and since this area isn’t rich in limestone it always leaves me guessing. Somehow two or three of the boulders must have at least some limestone in them. I first found this moss on just one stone years ago and now it is on at least three of them, so it must be happy here.

Another rare moss that grows here is the glittering wood moss, also called stair step moss because of the way new growth comes up out of the midrib of the previous year’s growth. It looks delicate but I’ve seen it encased in ice in winter and still looking fine in spring. Not surprising since it can withstand conditions in the Arctic tundra. It sparkles in the light so “glittering” is a good description.

For years I’ve thought that snow load was what made our evergreen ferns splay out on the ground but this year we have no snow and they are still hugging the ground, so that theory has to be let go of. I recently read this on Westborough Massachusetts Community Land Trust page: “When the green fronds are on the ground, warmth from the earth keeps them warmer than they would be if they stood up in the wind and cold air. The fern’s stems weaken near the ground in autumn, helping the fronds to fall over.” That does make sense but I wonder where that information originally came from. I believe the fern in the photo is a marginal wood fern, but I didn’t check for spore cases.

A big old red maple tree had fallen and someone had come along and cut off all its branches. This tree had target canker but that doesn’t kill trees, as far as I know.

Target canker won’t kill a tree but it can certainly keep one busy by causing its bark to grow in circular patterns of new, thin bark plates, which helps protect it from the canker. According to Cornell university: “A fungus invades healthy bark, killing it. During the following growing season, the tree responds with a new layer of bark and undifferentiated wood (callus) to contain the pathogen. However, in the next dormant season the pathogen breaches that barrier and kills additional bark. Over the years, this seasonal alternation of pathogen invasion and host defense response leads to development of a ‘canker’ with concentric ridges of callus tissue—a ‘target canker.’” You can see the pattern of new, thin bark plates the tree grew each year in this photo. I count at least ten, so that means this tree fought off the invader for at least ten years. There are some things which once seen can never be forgotten, and target canker is one of those.

I saw what I think was a white cheese polypore on a fallen branch. It grows on hardwood logs and causes white rot, and gets its common name from its scientific one (Tyromyces chioneus). Tyromyces means “with a cheesy consistency,” and chioneus means “snow white.” These mushrooms are big enough to be seen from a distance and when they are fresh, they have a pleasing fragrance that some think is like cheesecake. Mushroom Expert. com says it is “just about the most boring mushroom going,” but it is a winter mushroom and I’m always happy to see mushrooms in winter. There is also a blue cheese polypore and a green cheese polypore.

From boring to beautiful; this must be the most colorful display of turkey tail fungi that I’ve seen. It was beautiful, with its many different colors all in the same growth. No matter how many times I come here I always see something I’ve never seen before, and that is why it pays to revisit the same places again and again.

I was surprised to find a little ice on the ledges. It has been cold some nights but all in all this has been a very mild winter so far. I doubt there is any ice to speak of in the deep cut rail trail where ice climbers usually practice.

This is one of my favorite reasons to visit Beaver Brook; to see what I call the “disappearing waterfall,” because it only appears when we’ve had enough rain to get it going. It’s a beautiful thing and in the spring, I’ve seen people standing in line waiting to get to the spot where you can get the best photo of it.

I saw two splotches of color on the end of a log and I thought I recognized them.

As I thought, they were wrinkled crust fungi (Phlebia radiata) but they weren’t quite as colorful as others I had seen. I suspected they were young examples which might change as they aged, so I decided to return in a week to see if they had. These winter fungi are rare in my experience and well worth a second look.

This photo of a wrinkled crust fungus I took years ago shows what I was hoping to find upon my return but no, the fungi in the previous photos hadn’t changed at all. A quick online search showed that they can be very beautiful like this example or rather plain like the previous example. Like many things in nature, finding them is just a matter of being in the right place at the right time and paying attention. Unlike some fungi it’s hard to predict where or when they’ll choose to grow, though they do seem to like cold weather.

And speaking of being in the right place at the right time; as I was leaving Beaver Brook after my second look at the wrinkled crust fungi the afternoon sun decided to shine right up the brook. It was something I had never seen happen before and it seemed like a final, beautiful exclamation point to mark the end of my journey through a place filled with beauty.

Look at places no one looks at, so you can see the things no one sees.
