Posts Tagged ‘Conifer Parchment Fungus’

I hope everyone had a nice Christmas. Our presents from nature were temperatures in the mid-30s F. and plenty of sunshine but we’ve also had some cold, as this frozen view of Half Moon Pond in Hancock shows. We have no snow in my corner of the state though, because it seems to warm up ahead of every storm and we see rain instead of snow. That’s a good thing because just one storm last week would have dropped over two feet of snow.

Pressure cracks in ice are caused by stress, which is caused by fluctuating temperatures in the ice, wind, or waves. Some are contraction cracks, caused by the top surface of the ice sheet shrinking quickly. I think that’s what this crack on the pond ice in the previous photo might be. There are also wet and dry cracks. Dry cracks obviously have no water in them like this one. Ice can make some very strange, eerie sounds as it changes and sometimes this pond sounds like a Star Wars movie. This crack went all the way across the pond.

There seems to be plenty of seeds and other food for the smaller birds this year, especially since the asters seen here along with goldenrods and so many other late blooming plants grow many millions of seeds each year. All of these seeds are what help small birds and small animals through winter.

And they do get eaten, as this aster seed head shows.

Though the smaller birds seem to have plenty to eat things might be a bit difficult for larger birds like turkeys. Last year was a mast year and millions of acorns and white pine cones fell; easily more than I’ve ever seen, and turkeys, deer, squirrels and other animals had a bountiful year. But as is often the case when trees grow so much fruit, they need time to recover. In the following few years the harvest can be meager, and that’s what has happened this year. Last year I saw more acorns fall than I ever have and this year I’ve seen fewer fall than I ever have, and turkeys and larger animals are now paying the price.  Add to that a layer of snow like that seen here in Hancock, and there could be a serious thinning of the flocks and herds.

Technically a group of turkeys is called a “rafter” rather than a flock but I doubt they care. This one had to come over and see what I was up to. Here in New Hampshire we see turkeys chasing people on the news fairly regularly. They also have a habit of standing in roads. Why, I don’t know.

The way some of these photos show a snow pack and others show none you might think they were taken in different seasons but no, it’s just a matter of a few miles between snow and none at all. In fact looking at this colony of heartleaf foam flowers (Tiarella cordifolia) one might be fooled into thinking it was spring, but they’re an evergreen plant and look like this even under snow. Come mid-May they’ll be covered in small white flowers with long stamens, and it is these “foamy” flower stamens that give the plant its common name. It’s so nice to see green plants in December.

Mosses like this delicate fern moss (Thuidium delicatulum) are non-vascular plants and most if not all are evergreen. I love seeing them at all times of year but especially in winter when there is so little green showing. This moss changes color from deep green to bright lime green when it starts getting cold and it always looks orange to me in the fall, but I’m colorblind so I’m sure it’s just me.

Last year I found this odd, sprawling little plant that I had never seen before. I showed it on a blog post and helpful readers told me it was a spikemoss, which I hadn’t heard of. I went back to see it this year and it really hadn’t changed but I tried to look it over a little more carefully and I did some reading about it. I believe this example is meadow spikemoss (Selaginella apoda.) Spikemosses are considered “primitive” seedless (spore bearing) vascular plants and therefore aren’t mosses at all. This pretty little plant is more closely related to the clubmosses, which are also spore bearing vascular plants known as lycopods. It doesn’t appear to be evergreen like the clubmosses however.

I didn’t look closely at this fern but I think it might be an eastern wood fern (Dryopteris marginalis) which is also called marginal wood fern because of how its spore bearing clusters are placed in relation to its pinnule (leaf division) margins. We have a few evergreen ferns and like the mosses they add much to the winter landscape. They might look delicate but I’ve seen them grow on even after being encased in ice.

Polypody fern (Polypodium virginianum) is another of our evergreen ferns but it doesn’t look delicate at all. In fact if you run your hand over its fronds you’ll find that it feels tough and leathery. This fern is also called rock polypody or rock cap fern  because it is almost always found growing on stones. They are one of just a few vascular plants that can rehydrate after drying out, much like mosses do.

The sori of the polypody fern are considered naked because they don’t have the thin tissue covering, called an insidium, which many other ferns have. I think the little clusters of sporangium look like baskets of flowers. Though small they can be seen with the naked eye. The druids thought this fern had special powers because they found it growing near oak trees. Its roots and leaves have been used medicinally for many centuries and its name appears in some of the earliest herbals and botanical texts.

Milk white toothed polypore (Irpex lacteus) is a resupinate fungus, which means it looks like it grows upside down, and that’s what many crust fungi appear to do. This is a very common winter fungus that grows on the undersides of limbs. The “teeth” are actually ragged bits of spore producing tissue which start life as pores or tubes and then break apart and turn brown as they age. This example was very young and  shows what look more like pores than teeth at this stage. If you pick up a fallen limb and touch something that feels cold and rubbery, it might be one of these. They are very tough and can stand all the snow and cold that winter can throw at them.

Another tough fungus is the turkey tail (Trametes versicolor,) but this one feels leathery rather than rubbery. This is a common fungus that can be found just about anywhere but the beautiful blue, purple, and orange ones are rare in this area. It seems to depend on the year I’ve noticed; sometimes most of them are shades of brown but in some years many will lean towards blues, purples and oranges. I have no idea what determines their color and apparently science doesn’t either, because I’ve never been able to find a single word about what colors them in print.

I’ve seen several trees with these markings on them and I think it might be the start of a bright yellow crust fungus called conifer parchment fungus (Stereum sanguinolentum.) This fungus is also called bleeding parchment because of the blood red liquid it exudes when it is damaged. It causes heart rot in conifers and is a death sentence for the tree. It seems to be very widespread because I’ve seen it in almost every bit of woodland I’ve been in.

A single terminal bud and two lateral buds in red or sometimes pink help identify striped maple (Acer pennsylvanicum.) In late April or early May the bud scales on these buds will open to reveal the beautiful pink and orange buds, which are some of the most beautiful the things one can see in the spring forest.

Many things in nature will turn blue when it gets cold enough. Ice can be blue and so can the sap of the white pine tree. I’ve also seen the white striations that give striped maple its name turn blue. This is the only maple tree in New England that has bark that is striped like this. Other names for the tree are snake bark maple, moosewood maple, goosefoot maple, Pennsylvania maple, and whistle wood, because the soft pith makes the wood easy to hollow out and make whistles from. Native Americans used the bark of the tree to treat many ailments including coughs and colds.

A burl is an abnormal growth on a tree that grows faster than the surrounding tissue. Scientists don’t fully understand why it happens but burls are thought to grow on trees that have been weakened by stress or damage. Once the tree’s defenses have been weakened insects and/or fungi can attack and cause the abnormal growth. Woodworkers prize burls very highly and make some beautiful bowls and other things from them which can sometimes sell for thousands of dollars. This one grew on a maple and was quite large.

Bunch gall is another plant deformity that appears on Canada goldenrod (Solidago canadensis) at the very tip of the stem. A gall midge (Rhopalomyla solidaginis) lays its egg in a leaf bud and when the larva hatches the plant stops growing taller but continues to produce leaves in a “bunch” like that seen here. Since the midge only lays its eggs on Canada goldenrod it makes this plant easy to identify.

I was working one day and this spider crawled up to me and watched for a while. After letting me take a couple of photos it walked off to wherever it was going. It was about as big as a quarter (3/4”) from leg tip to leg tip. I don’t know its name but it could move very fast when it wanted to.

This is how the sky often looks as I drive to work at 7:00 am at this time of year. It’s a great gift that costs nothing but my being there to see it. I hope all of you received similar gifts this year.

A wonderful gift may not be wrapped as you expect. ~Johnathan Lockwood Huie

My small climb up along 40 foot falls that I wrote about in my last post inspired me to try something bigger, so last Sunday I decided to climb Hewe’s Hill in Swanzey. A diagnosis of COPD took the wind out of my sails for a while and I wondered if I’d ever climb again, but the medicines they have given me seem to work well and I was able to climb on this day at least as well as I could last year. I started by walking through this frosty meadow.

At about 20 degrees F. it was cool but there was little snow to be seen, so I hoped for a trail without ice. This trail is well traveled and ice is always a problem when constant foot traffic packs down snow and turns it into ice.

Thankfully the trail was ice free, probably because the hemlock boughs overhead have kept a lot of the snow from falling on it. We’ve also had rain and warm temps and I’m sure that helped. I was glad to see it, because I’ve been here when the ice was so bad here I had to leave the trail and go into the woods to make it up the hill.

I think it was about 10 years ago when this hemlock (Tsuga canadensis) was wounded, and I think that because I counted the rings on the scar. I’ve read that hemlock is the only tree that heals scars with growth rings that can be counted.

I also saw a large number of hemlock trees with this yellow crust fungus on them; more than I’ve ever seen. I believe it is the conifer parchment fungus (Stereum sanguinolentum,) which is also called the bleeding parchment because of the red juice they exude when they’re injured. The examples I saw were very dry and thin, almost as if they were part of the bark, and though I tried to scratch one with my fingernail it remained undamaged. Conifer parchment fungus causes brown heart rot, which is a reddish brown discoloration in the wood of conifers. This tree and many others I saw won’t be with us much longer, I’m afraid.

More ice needles than I’ve ever seen in one place grew all along the center of the trail, meaning the soil was saturated. Groundwater at the soil surface is one of the requirements for ice needle growth, and the other is a below freezing temperature right at the very surface of the soil while the soil and groundwater remain thawed. Hydrostatic pressure forces super cooled groundwater out of the soil where it freezes instantly into a needle shape. 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. Each needle is hexagonal and several will often freeze together into ribbon like bands like those seen here. As they grow they sometimes force the forest floor to heave up, which can be seen happening here.

There are many small holes in the ground made by chipmunks, snakes, and other animals, and these holes often grow hoar frost around their openings. This frost forms when the warm moist breath of the earth meets the cold air at the surface.

The trail gets darker in spots because of overhanging evergreens but on this day it clouded over and made it seem even darker.

I saw some colorful bracket fungi growing in the crack of a tree but I’m not sure what they were. I am sure that they were frozen solid, whatever they were.

I couldn’t account for the beautiful colors of this fallen limb, and I still can’t even guess what would have caused it except weather and age.

A blue jay lost a feather at some point, but on this day the woods were totally silent with no bird songs and no chatter from chipmunks or squirrels. It seemed very strange to have it so quiet.

The steepest part of the trail is near the summit so I knew I was almost there at this point. I was huffing and puffing but no more so than last year or the year before so that was a pleasant surprise. I do know that nature can heal because I’ve experienced it but I don’t know to what extent that healing can happen. I think maybe the only thing that is holding me back is me, but I’m keeping an open mind and believing, and will be very grateful each time I reach a summit.

You don’t realize how much water travels through the soil under our feet until winter. There really is an incredible amount of water moving about in this area, even on our hills.

My daughter and son in law were with me on this climb and all of us tried to move the 40 ton glacial erratic named Tippin Rock, but it wouldn’t budge. I think it was frozen right to the bedrock it sits on. I was a little disappointed because I wanted them to be able to see it move. For new readers, this boulder rocks back and forth just like a baby cradle when you push on it in the right spot, but apparently not in winter.

The big stone has quite a crack in it and someday it might be two stones, which would be too bad. It is a local legend.

The sun had gone, the sky was milk and the views were poor, but since the view isn’t why I climb it was little more than a passing annoyance.

One thing the views from here always show though, are the endless miles of unbroken forest stretching out in all directions. When you stand in such a place you can’t help but wonder, if it was 1760 and you stood here with only an axe head and a gun, what would you have done? It must have been just a bit overwhelming.

I’ve had a great fear of heights since I fell out of a tree and fractured my spine when I was young  so this is as close as I dared to get to the cliff edge. I wanted to show you what a forest looked like from above, but this is the best I could do. You can believe me when I say that this is a drop you would never survive.

There are some huge granite outcrops up here. That tree is a fully grown white pine.

I saw lots of amazing things up to this point but the main reason I chose this hill to climb was so I could visit my friends the toadskin lichens (Lasallia papulosa.) Though I expected them to be very dry from lack of rain or snow a few surprised me by being deep, healthy green. This is their natural color when they’ve had plenty of water and are happy. These lichens attach themselves to stones at a single point that resembles a belly button, and that means they are umbilicate lichens. I always feel as if I’m looking deep into infinity when I look at a toadskin lichen and I may be; there are many who believe that lichens are virtually indestructible and therefore immortal.

Though I doubt toadskin lichens like drying out I kind of like the way they look in their dry, ashen state. They are much like a potato chip when dry and they’ll break almost as easily so I only touch them when they’re green and pliable.

These toadskin lichens were under a good two or three inches of ice and that ice acted like a magnifying glass. Those black spots on the upper one are the lichen’s apothecia where its spores are produced, and without ice magnifying them they’re about the size of the head of a common pin. It’s kind of amazing to see them so big in a photo.

Only in the woods was all at rest for me, my soul became still and full of power. ~Knut Hamsun
