Observation 9204: Pluteus Fr.
When: 2008-08-14
Herbarium specimen reported

Notes: last year I found this fungus on old aspen log but it did not completely look like what I thought was P.cervinus or P.petasatus, then this year I got a microscope and found it had round spores (P.cervinus & P.petasatus have ellipsoid spores) it is a dark brown caped mushroom, with white stalk,pinkish gills(but not as pink as P.cervinus) I noticed that compared to some other wood fungi it had very littl mycelium in the damp log,
I think it is Pluteus patricius but Helen -Brendson auther of “Mushrooms of Western Canada” said P. patrcius is the new name for P.petasatus, is this true?
