When: 2008-03-08

Collection location: Mountain View, California, USA [Click for map]

Who: Douglas Smith (douglas)

Specimen available

Notes:
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.
