Observation 96758: Pluteus cervinus group
When: 2012-06-03
No herbarium specimen

Notes: These were found growing on conifer debris in the woods at ~ 6560 ft.
They were thrown into the Pluteus petasatus pile at the SFSU Spring Fungi Class but they really don’t seem to fit that species.
The overall structure of these was that they were rather small and delicate.
The spores were quite variable in size but most were in the range of 9.0-12.2 X 7.1-10.4 microns. This is quite a bit larger than what is reported for P. petasatus(6-10 X 4-6 microns).
The gill cystidia were not prolific. The last photo shows a typical cystidia that seemed conical , ~ 60 X 25 microns, with rather short blunt horns.
They seem to be close to what Dimitar Bojantchev calls DB15314 on the Mushroom Hobby website. http://mushroomhobby.com/...

but unfortunately after getting a spore print and small piece of gill for a one shot scoping, the specimens were lumped into a display table and eventually discarded. I did not look for clamp connections. These appear to be fairly common in the Spring in the Sierras, but for some reason have been commonly labeled Pluteus petasatus….I suppose for lack of interest and a lack of a Pluteus “expert”.

The external aspect and the spore size rule out P. petasatus

Did you check for clamp-connections?
