Observation 92286: Psathyrella bipellis (Quél.) A.H. Sm.
When: 2011-01-23
Herbarium specimen reported

Notes: Found on wood chips, under eucalyptus and live oak.

First micro-shot is of the gill edge at 400x in KOH. The cheilocystidia are broadly lageniform, with some inflated ends almost capitate.

The second micro-shot is of the cap surface at 400x in KOH. The cap surface in an epithelium, with a few thin long hyphae at the very surface. No gelatin, no pileocystidia.

The third micro-shot is of the gill face at 400x in KOH. There are 4-spored basidia, and many numerous pleurocystidia, certainly at least 1 per 10 basidia. The pleurocystidia are similar to the cheilocystidia, lageniform.

THe forth micro-shot is of spores from the gill at 1000x in KOH. The spores are ellipsoid, grey, smooth, with a clear germ pore. The apr. ave. size of the spores is 14 × 8 um, with 1.5 um wide germ pore.

This matches well with the descrip. in the Psathyrella key in Funga Nordica for P. bipellis, or aka P. odorata.
