Observation 143262: Psathyrella (Fr.) Quél.
When: 2013-08-19
No herbarium specimen

Notes:
growing in a planter box with marigolds.

cystidia are few, pear-shaped with rounded ends; more frequent on edge of gill than on face of gill.

P. bipellis (http://www.mushroomexpert.com/psathyrella_bipellis.html) is a close match, but the caps didn’t have a pinkish color and these stems are really thin.

P. conopilus (http://www.mushroomexpert.com/parasola_conopilus.html) also close, stems were shorter but then these were growing under a half-covered lid;

One of dozens of species in subgenus Psathyrella, see Smith’s book. Pleurocystidia are present? Did you measure the cystidia? Did you check for long thick-walled setae on the pileipellis that Parasola conopilus should have? Or in CA Psathyrella atrospora is rather common, but this doesn’t really look like them.

P. conopilus a better match

looking around MO, it seems P. conopilus is a visually closer match.
