Each trait you describe is exactly the same as the several frutings I have encountered this fall.

Douglas, sorry to contribute to what may seem to you like endless micro frustration, but some info is better than no info. Sometimes I get some useful insight from my scope. Actually, I am currently waiting for the bio dept at my job to review/replace some scopes. They’ve told me they will eventually hook me up with a 1000×.

Link below is to a more recent observation of the exact same fruiting of Gymnopilus as seen in this obs (112840). I attempted to mount a section of a pileus in Congo red. My knowledge of micro traits is insufficient for me to decide if any of the photos are useful.

I think this is the species that tends to fruit late in the season, usually in large clusters and at times with very large fruiting bodies. It may bruise greenish, is not fragrant and is somewhat bitter. In my experience it usually fruits from buried wood or roots and not on logs and stumps. It is macroscopically distinct from the G.junonius/G. luteus complex.

Just to confuse things…

I wish you had a scope with better resolution there. A number of spores look more like Galerina spores really, quite a few look like they have a plage, and although roughened, the spores don’t really show clear warts. But it is hard to tell from 400×.

I had brought home a collection awhile back.

But the mushrooms sat around and eventually I just threw them away. If I get back to the collection site I’ll grab a few. Great big rainstorm on the way, so the window is small.

I don’t know how to examine pileus trama. My scope is old and only max 400×. Any suggestions?

do you have these specimens dry?
if you do, can you look at the Pileus trama??
