Observation 85023: Rhodocollybia butyracea f. asema (Fr.:Fr.) Antonín, et al.
When: 2011-12-21
Herbarium specimen reported

Notes: These were growing individually on humus near tanoak, Doug fir and redwood.
The caps were up to 5.2 cm across and hygrophanous.
The gills were mostly adnate, thin and thinly eroded.
There was some white hairs at the base only.
The spore print(pictured) was sl. orangy and appeared to be dextrinoid in Melzers.
The spores were ~ 5.0-6.0 X 3.0-3.8 microns, and smooth.
Could not see any Cheilocystidia but perhaps some clusters of Caulocystidia.
There was a slight odor when the cap was cut but I couldn’t identify it (not unpleasant).

It comes in many colour forms, this one reminds of f. asema. They should have cheilocystidia, but they are usually scarce, and the length of the spores can vary a lot.
