Summary: Exidia Resica

Thank You Irene!

Exidia recisa has “rod shaped” spores. I would call them more sausage shaped, but rod shaped is close enough. Lots of similar pictures can be found with a google search for Exidia resica.

Summary: This species

seems similar to what often is called Exidia recisa in USA.
It does resemble the ones I call recisa and find in early spring on Salix (without hymenial warts and somewhat different habitus), but it has also been described to have warts occasionally. Is this just a variety then, or a closely related species?
It looks to me more like an intermediate between recisa and truncata (which is much darker)..

Summary: 5255

Yes, I think OB# 5255 is the same.

I’m off to get a new blade for my scalpel. Maybe I can get a super thin slice to show some basidia. The thick slices I’ve been using pop back up after I squish them down.

Summary: Could be the same

in obs 5255 too.
At least the spores are telling us that it’s not a Tremella. They have more or less globose spores.

How are you doing the preparations for the microscope?
If you cut a very thin slice (radially) from the hymenium and put it on the glass, add a drop of water and put the cover glass on top, then tap gently on it with the backside of a pencil or something, until the piece of the mushroom is completely crushed and flattened, it should be possible to see some more structures in the hymenium. It’s not easy to separate the basidia from the embedding material, but if you get it thin enough, you may succeed.

Summary: Dan

Thes are very common in West Virgnina so common i decided to do a little study on them as far as how they grow. I also notice that they grow high in trees. and I have found them on the ground. This is what I have noticed. They start high up in the trees the wind blows or some force of nature knocks down the limb and they continue to grow on the twigs on the ground. They will even sprout several years after the branch has fallen but they become darker in color. When they are in the trees they are a lighter brown. I have artificially grown these this year in branches that had fallen two years ago.

Summary: Most common winter Jelly.

I’m surprised these little brown jellies are turning out to be so mysterious. They are by far the most common winter jelly fungus. Most are small, less than an inch across, and they grow from small branches, both on the ground and high up in trees. I found quite a few of them randomly scattered on the ground like fallen leaves.
Spores can be seen in this ob:

Compare to tree ears found at the same park on the same day.
http://www.mushroomobserver.org/34825

Note the smooth round edges on the wood ears; compare to the sharp ridges on the fungus in this ob.

Compare to Tremella foliacea, a similar fungus that also grows in winter, but grows in large clusters and prefers larger pieces of wood.

Nathan posted something similar the other day.
