Specimen available

On soil with woody debris in hardwood forest.

Cap somewhat wrinkled/corrugated. Stature robust for a Psathyrella. (My first impression was, “what kind of Agrocybe is this?”)

Spores 8-12 × 5-6, with Q quite variable. Cystidia without fingerlike projections.

I preserved/saved a small piece of the seemingly interesting mushroom.


Smash mount in Congo red
