1. Pond Ice

This photo of pond ice does something to satisfy that abstract craving that I have every now and then. It seemed to want to be in black and white so I granted its wish, even though it hardly changed from the original. These shards of ice were quite long and looked like they had just started to form. The process of ice crystals beginning to form in super cooled water is called nucleation.

 2. Bracket Fungi on Bracket Fungi

There were bracket fungi growing on this tree when it fell. Bracket fungi have their top toward the sky and bottom toward the soil but when the tree they grow on falls, what was horizontal can become vertical. They solve that problem by growing young, horizontal bracket fungi from the older ones that now grow vertically. That’s determination.

 3. Bracket Fungi on Bracket Fungi

A shot from another direction shows that these bracket fungi have teeth.  I think they might be Steccherinum ochraceum, which is a tooth fungus that can form brackets and is strongly affected by gravity and sunlight.

4. White Pine Bark

This old white pine had very colorful bark. There were several other old specimens growing quite close together but this was the only one that looked like it wanted to be as colorful as a sycamore.

 5. Crumpled Rag Lichen aka Platismatia tuckermanii

Last year I did a post with this lichen in it and at the time I thought it was an example of a spotted camouflage lichen (Melanohalea olivacea), but after doing a little more research I’m now fairly certain that it’s a crumpled rag lichen (Platismatia tuckermanii .)The large greenish brown discs are apothecia or fruiting bodies, and they help identify this lichen. I usually find these on birch limbs.

6. Heather Rag Lichen

I think this is an example of a lichen called heather rags (Hypogymnia physodes), but there are so many that look almost the same that I can’t be completely certain. This lichen has gray, inflated, puffy looking lobes like heather rag lichens do, but so do many others. Heather rags gets its common name by its habit of growing on unburned heather in the United Kingdom, but it is also quite common here in the north eastern U.S.  No matter what its name, this example is a beautiful lichen.

7. Heather Rag Lichen Closeup

Lichen books say to look for soralia bursting from lobe tips when identifying heather rags lichens. Soralia are clusters of intertwined alga and fungi that form a granule-like mass, and I think I see a few of those in this close up. Soralia are a vegetative way for lichens to reproduce. Once separate from the main body of the lichen they will start new lichens, just as taking a cutting from a plant produces a new plant.

8. Small Brain Jelly Fungi

These yellow fungi looked like tiny dots, about half as big as a pencil eraser, on a fallen log. It wasn’t until I saw the photo that I realized they were very small examples of “brain” fungi, possibly Tremella mesenterica, also called witch’s butter. If so they are the smallest examples I’ve seen of that fungus.

9. Pear Shaped Puffball

I saw some pear shaped puffballs (Lycoperdon pyriforme) on a log and noticed that the darker, outer skin had split to reveal a lighter inner surface.  I assumed that this meant that they were ready to release their spores and poked one with a stick. Sure enough it puffed out some spores, which show as light gray powder in this photo. Inhaling enough of these spores can result in lycoperdonosis, which is a respiratory disease that starts out like a cold. The disease causes symptoms similar to those found in pneumonia, and is sometimes misdiagnosed as tuberculosis or pneumonia. If left untreated it can be fatal.

10. Sweet Birch Seeds aka Betula lenta

If you see a cherry tree with this type of growth on it you have found a sweet birch (Betula lenta,) not a cherry. I’ve pointed that out because its bark looks a lot like cherry bark and they are sometimes confused. The cone like object pictured is a female catkin. These catkins begin to shatter and release their seeds in late fall. The seeds, a few of which can be seen in the photo, are called nutlets and are winged, much like an elm seed. The easiest way to identify sweet birch is by chewing a twig. If it doesn’t taste like wintergreen, it isn’t sweet birch. Native Americans boiled the sap and made it into syrup. If enough corn is added, birch beer can also be made from it. After chewing quite a few twigs it seems to me that syrup or beer made from this tree would taste a lot like oil of wintergreen, and I don’t know if I could handle wintergreen flavored flapjacks.

11. Plagiomnium cuspidatum Moss

I found a large patch of baby tooth moss (Plagiomnium cuspidatum) growing on a flat boulder in the sun. This moss can be a little tricky to identify because it has two types of stems with different growth patterns. Vegetative stems trail like a vine and stems with fruiting capsules (sporophytes) stand upright as they are in the photo. Each leaf has tiny serrations from its tip down to about mid leaf, and that’s a good identifying feature.

 12. Plagiomnium cuspidatum Moss Immature Sporophytes

The sun had melted a dusting of snow from the patch of baby tooth moss just before I found it and many of the sharply pointed  immature sporophytes had tiny drops of water clinging to them. When mature the sporophytes will be more barrel shaped with flat ends, and will bend until the capsules droop just past horizontal.

Go to the winter woods: listen there; look, watch, and ‘the dead months’ will give you a subtler secret than any you have yet found in the forest. ~ Fiona Macleod
