Who: Douglas Smith (douglas)

Specimen available

Found in the grass of an irrigated front lawn. Caps are hygrophanous, from dark brown to light brown. The caps are covered in light scales that fell off. They have a fibrous veil, that has remnants on the cap margin.

The first micro-shot is of the spores from the stipe apex in KOH at 1000×. The spores are smooth, smokey brown, and with a germ pore.

The second micro-shot is of the cap surface, in a radial section, in Meltzer’s at 400×. The surface of the cap is an epithelium, 2-3 cell thick.

The third shot is of the gill edge, and shows club-shaped cystidia. This is in Meltzer’s and is at 400×.

This all points to a Psathyrella species. Which one I’ll leave to Psathyrella geeks.
