Observation 127406: Psathyrella longipes (Peck) A.H. Sm.
When: 2013-01-31

Notes: These were growing singly, in deep duff, at the base of a hardwood.
Caps up to 3.3 cm across and hygrophanous.
The long stems were partially hollow and had some white tomentum at base.
Spore print was a purplish-black.
Spores were ~ 10.8-12.2(13.0) X 7.2-8.3(9.2) microns. Q(ave) = 1.49.
Did not see any pleurocystidia but there were clusters of cheilocystidia that was narrowly utriform to utriform, ~ 33-35 X 11 microns, and most with what looked like a “hood” on the head of the cystidia.(see photos).
P. longipes would probably be the first guess although the curiously ornamented cheilocystidia begs some questions.
