Observation 14437: Agrocybe firma ( Peck) Singer
When: 2008-10-08
No herbarium specimen

Notes: These little brown mushrooms were growing from well rotted wood. I’ve seen them in previous years, but I have not been able to identify them. They come out in a single large flush in October and then disappear till the next year.

Spore print is cigar-brown, and the smell is green-bitter (like the way a bitter medicinal herb would smell). I did not taste them.

Gregarious but not cespitose

…seems more consistent with Galerina than Pholiota. The brown looks more purple-brown in the photos than I recall. I remember it as ‘Agrocybe-brown’.

Linnaeus is reported to have described genera as “countries on a map with surrounding countries on all sides”.

Probably need more detail.

Need more detail perhaps, they do look like they are hygrophanous, maybe. They might be a Psathyrella, even with the cigar-brown spore color. There is also Kuehneromyces, which is really a non-viscid hygrophanous Pholiota. Some call this a section of Pholiota, and some call this a section of Galerina… it is common enough in the North East, in groups, so I’ve read. Although still no one has posted obs. of them here… The spore is supposed to be more medium brown, not as dark as cigar-brown, and mostly they should have a fibrous veil.

Need to know what the spores look like, smooth or rough, germ pore or no, and if the cap is cellular or a cutis. That might help get to genus, and then more info to get to species…
