Posts Tagged ‘Tinder Fungus’

As I’ve said recently in previous posts it has been mostly sunny, hot and dry here so far this summer and now a large part of the state is once again in a moderate drought, for about the third year in a row. Small streams and wetlands are again drying up so last Saturday I decided to go and see how Beaver Brook in Keene was faring. I hadn’t done a post about the place since February so I thought it was time. I like to see the seasonal changes that take place in the various places I visit. It’s how I really get to know the places and the plants that grow in them. The trail through this particular place was once a road north out of Keene, but it was abandoned in the 1970s when a state highway crossed it. Now nature is in the process of reclaiming it.

The first flower I saw blooming on this day was the little lobelia called Indian tobacco (Lobelia inflata.)

This lobelia gets its common name from its inflated seed pods, which are said to resemble the pouches that Native Americans carried their smoking materials in. It’s too early for those but there were plenty of the tiny blue flowers to see.

There is lots of poison ivy here (Toxicodendron radicans,) all along the left side of the old road as you walk up it, so it’s best to wear long pants, hiking boots and socks if you come here. That’s what I always wear anyway and, though I’ve heard you can get a rash just by getting the plant’s oils on your clothes, I’ve walked through knee high poison ivy plants hundreds of times with no ill effects. I tend to be somewhat immune to it though; if I get it on my hand it stays there and doesn’t spread.

Just in case you do start to itch, jewelweed (Impatiens capensis) grows along the right side of the road. If you crush the stems of jewelweed and rub the sap on poison ivy blisters it will stop the itch. It doesn’t cure the rash but it stops the itch as well as calamine lotion does. There are people out there who don’t believe this is true but I’ve used it many times and it works, so I’ll continue using it and the non-believers can scratch. With plants being used even in cancer and HIV treatments I’m not sure why some people have a hard time believing that a plant can stop a simple itch, but they do.

I was shocked to see that a huge portion of ledge had fallen; shocked because I used to kneel right where the stone pile is to get photos of the helleborine orchids that grew there. The stone is white (actually sort of pink) because it is feldspar, and the biggest piece lying at an angle behind the plants is as long as a car. It’s always risky to walk near ledges and this is why. Ledges line almost the entire road and so many years of water seeping between the layers of rock and freezing in winter has cracked them badly, so none of it is stable; it’s all very loose. The city should come in with an excavator and peel away all the loose stone but they don’t even cut brush correctly here, so I know that isn’t going to happen. I’ll be staying well back from the ledges from now on.

The reason the ledges are here at all is because this road was hacked out of the stone of the hillside back in the 1700s. This photo shows a hole in the feldspar made by a star drill. A star drill is a pointed, five sided, two foot long piece of steel. You can tell a star drill was used because you can see the star, as it shows in this photo. To use it one man holds the drill while another strikes it with a sledge hammer. After each hammer blow the drill is turned a quarter turn and then the hammer falls again and again the drill is turned, and so on until a hole is made. Once you have a hole you fill it with black powder, insert and light a fuse, and run as fast as you can. At least, that’s what you do if you happen to live in the 1700s. Feldspar is a softer stone but it was still a tremendous amount of work. After all, someone had to clean up all that blasted stone.

Stone isn’t the only thing falling here. Trees fall regularly and many get hung up on the electric lines that still run alongside the road.

In some places the ledges pull back away from the road as you can see there on the left, but in many places the ledges come right up to the road. You can also see how the trees lean over the electric wires on the right. It’s all about light and plants lean towards the light to get more of it, so this will never stop happening no matter how many trees fall or how many are cut. The hole in the canopy that lets in light is over the road.

The double yellow no passing lines still run down the center of the road even though there hasn’t been a car here for nearly 50 years.

The old guard posts still line the road but they are slowly rotting away.

I met an old timer up here once who told me that he had seen Beaver Brook flood badly enough to come up over the road and I believe it, because you can see where it’s eating away at the edge of the road all along it. This old concrete culvert finally gave up and slid into the brook.  You can also see the size of the boulders that the brook tosses around like pebbles when it rages. And it does rage; I’ve seen it roaring and angry enough to make me leave this place, but normally it just giggles and chuckles along beside you as you walk along.

On this day though, there was little chuckling and giggling to be heard, because the brook had all but dried up to a gurgle. I could walk from bank to bank in this spot without getting my feet wet, and that’s something I’ve never been able to do before. In a normal year I would have been in serious trouble if I had tried to stand in this spot, though it’s actually getting hard to remember what a normal year was like. It seems we’ve had extreme weather take over our thoughts for the past few years.

It’s time to say goodbye to thimbleweed (Anemone virginiana) for another year. The seed head will grow on for a while longer and then the seeds will fall.

Purple trillium (Trillium erectum) was also busy making seeds. Trilliums are all about the number three and multiples of it, so the seed chamber has six parts. The fleshy seeds are prized by ants because they have a sweet, pulpy coating that they eat, so many of the trilliums we see have most likely been planted by ants. It takes about five years for a trillium to go from seed to flower.

Oyster mushrooms (Pleurotus ostreatus) grew on the end of a log. Though they look like bracket fungi oyster mushrooms have off center stems that attach to the log they grow on. Mushrooms are often eaten by tiny worms called nematodes that live on plant and fungal tissue, but not oyster mushrooms. Scientists discovered in 1986 that oyster mushrooms “exude extracellular toxins that stun worms, whereupon the mycelium enters its body through orifices.” What this means is that oyster mushrooms are actually carnivorous. They also consume bacteria in order to get nitrogen and protein. These examples looked like they had slug damage, so the mushroom apparently hasn’t evolved a defense against them.

I saw the most colorful tinder fungus (Fomes fomentarius) that I’ve ever seen. It had bands of purple and orange and red and that’s unusual, because they’re normally gray, brown, and sometimes a little cream colored. I’ve also seen these tough, woody fungi with squirrel teeth marks all over them in the past but I didn’t see any on this example. I think the squirrels are after the algae that grow on the fungus. They do the same thing with certain lichens. I can’t explain the colors; it’s something I’ve never seen in person or in books.

I saw a very dark colored toad that looked black in person but looks dark green in the photo. It looks like it has somehow lost most of its left front foot. Or maybe it was making a fist. It seemed to hop just fine.

I made the treacherous climb down the steep gravel embankment that leads to Beaver Brook Falls and found what I expected; barely a trickle. The water usually falls with a roar heard from quite far away but on this day there was a little splashing going on that hardly echoed off the stone walls of the canyon. I’ve never seen the falls with so little water coming over them.

This is what the falls normally look like and they probably look much like this right now, because since I went there last weekend it hasn’t stopped raining. We’ve had rain and storms every day since, totaling up to about 4 inches of rain here. We’ve even had flash flood warnings, so I suppose we need to be careful what we wish for in this age of weather extremes. From drought to flood in one post.

The air is impressively warm and close, as thick as honey. ~Lucy Foley

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.

Last Sunday dawned cold at only 4 degrees F so I waited until it had warmed up as much as it was going to before climbing Hewes Hill in Swanzey. The trail winds through mostly hemlock forest and is quite dark in places and I expected ice, so I strapped on my Yaktrax and set off across the hayfield in the above photo.

It wasn’t long before I was glad to be wearing the Yaktrax because there was ice here and there on the trail.

I’d bet that I’ve walked by this stone a hundred times without ever seeing anything interesting, but on this day I noticed that it was covered with concentric boulder lichens (Porpidia crustulata.) This lichen gets its common name from the way its fruiting bodies (Apothecia) grow in concentric rings around the center. I’ve only seen it two or three times and that led me to think that it was uncommon here, but now I wonder if I’ve just been walking right by them all these years.

We had one day with wind gusts near 60 mph last week so I wasn’t surprised to see this eastern hemlock (Tsuga canadensis) lying across the trail. I saw several more fallen trees as well.

The hemlock most likely fell because it had been weakened by the tinder fungi (Fomes fomentarius) that were growing on it. The spores from this fungus enter the tree through damaged bark and cause rot inside. It usually grows on hardwoods but can occasionally grow on conifers as well. This bracket fungus produces spores at all times of year but through spring and summer studies have shown that as many as 800 million can be produced in a single hour. The fungus is also known for its ability to stop bleeding and was recommended for that purpose by none other than the father of medicine himself, Hippocrates (460 – 370 BCE).

The fungal rot was white and clearly visible all over the inside of the tree. White rots break down lignin and cellulose and cause the rotted wood to feel moist, soft, spongy, or stringy. They can be white or yellow.

I heard crunching underfoot so knew I was walking on ice needles. For ice needles to form the air temperature has to fall below 32 degrees F right at the soil surface while the soil and groundwater remain thawed. Hydrostatic pressure forces the groundwater, sometimes super cooled, out of the soil where it freezes instantly into a “needle.” As more water is forced out of the soil the process is repeated over and over, and each needle grows in length because of more water freezing at its base. I’ve read that each thin needle is hexagonal in shape, and that needles have been found that were 16 inches long. The needles in this photo were no more than 4 inches long. They were very dirty.

Other ice growing on ledges was bigger; much bigger.

As is true on many of these hills and mountains the trail is steepest just before the summit.

The 40 ton glacial erratic known as Tippin’ Rock sits atop Hewes Hill on a slab of very flat granite bedrock. Legend says that it is called Tippin’ Rock because if you push in the right place it will tip. I didn’t know whether to believe it or not until I first saw it happen and then tipped it myself.

To give you an idea of the size of Tippin’ Rock and because I promised my friend Dave that I’d make him world famous, here he is actually tipping Tippin’ Rock last summer. We were shocked to see such a huge boulder rocking gently and almost soundlessly back and forth like a baby cradle. When you think about all of the forces that had to come into play for this stone to simply be here at all, but then to also be so perfectly balanced, it becomes kind of mind blowing.

Sometimes if a stump or log has decayed enough tree seeds can fall and grow on them. In this photo am eastern hemlock grew stilted roots over what was probably a stump that has since rotted away. From what I’ve seen any type of tree will do this.

The views weren’t spectacular but I sat for a while and wondered, as I often do, how the first settlers felt when they looked out over something like this. It isn’t hard when you’re up here to imagine nothing out there but trees and maybe a game trail to follow if you were lucky. And if you were very lucky you might have a gun, an axe head, and food enough for a day or two. I also often wonder if I would have had the courage to face such an immense unknown.

You really are in the treetops up here. Mostly oak treetops.

This is another unsuccessful attempt to show you how high you are when you’re up here. You’ll have to take my word that it’s quite a drop.

The views didn’t really matter because that’s not what I climbed up here to see. I haven’t seen my friends the toadskin lichens (Lasallia papulosa) since last fall, so I thought it was past time to pay them a visit. They prefer growing on undisturbed natural boulders rather than on man-made stone walls and in this area I’ve only seen them on hilltops, so I don’t see them often; only when I’m willing to work for it. We haven’t had any rain or snow lately so they were very dry, and when dry they usually turn from their normal pea green color to the ashy gray seen here. They also become very brittle.

Common toadskin lichens are umbilicate lichens, which means they attach to a substrate (usually stone) at a single point, like a belly button. That point is the lighter area in this example. These lichens also look warty, and that’s how they come by their common name. These examples were small at less than an inch across but I’ve seen them as big as 2 inches. They can be very beautiful.

The head of a pin is .06 inches (1.5 mm) in diameter and one of the toadskin lichen’s fruiting bodies (Apothecia) could easily hide behind one. The apothecia are where the lichen’s spores are produced. In this case they are tiny black discs with a sunken center that makes them look like a bowl with a thick black rim. The way that they sit on the body (thallus) of the lichen makes them look like they’d blow away in a breeze, but they are attached. This isn’t a great photo but it’s the closest I’ve ever been able to get to this lichen and it’s a fair bet that you’re seeing something you’ve never seen.

This photo shows how the apothecia are distributed over the surface of the toadskin lichen. Despite being quite dry this one was producing a lot of spores.

Mr. (or Mrs.) smiley face was there to greet me as I reached the bottom of the hill. I wonder if whoever painted it could have imagined that it would stay here so long and cheer so many people on. There have been times when my weariness has disappeared as the little smile put a smile on my face.

I’ll tell you what hermits realize. If you go off into a far, far forest and get very quiet, you’ll come to understand that you’re connected with everything. ~Alan watts
