Observation 27960: Agrocybe firma ( Peck) Singer
When: 2009-10-20
No herbarium specimen

Notes: These are some little brown jobs I have not been able to put a genus name on. They grow from rotting hard wood in early fall. The small mushroom on the left in the first photo is something else, Mycena pura probably.

includes pics and description of A. firma which seem to match this observation very well.

there is a (rare) species which looks quite similar to yours: Agrocybe firma. I think it exists in America too, may be it’s even a PECK species, if I remember right.
If you have a microscope, check the cuticule whether it is hymeniform or not.

The spore print is a strait brownish brown.

This is the same species seen here:

This one might also be the same thing:

is more or less elliptical, but variable with a few showing a rounding on one end, and some maybe better described as “egg shaped.” Tubaria? A couple pics of T. furfuracea spores I’ve just viewed seem to resemble these. Print color?
