I recently posted images of a colony of small ones of this species. This was a solitary individual and much larger that the ones found previously.
This species was previously in [i]Psathyrella[/i].
Olympus EM-1, (aperture priority), Olympus 4/3 50mm f2 macro, 1/40 & 1/25 at f8 ISO 1000, hand-held.
The stereos are crosseye.
