Thanks Drew,

P. Umbrosus sounds like a good match. I was very surprised to see Pluteus of any kind in December.

The log it was growing from is way too rotted to determine species, but there are no evergreens in the area.

is a good fit with emarginate gills, bulbous stipe base, on hardwood. It is hardwood isn’t it?

According to Else in this observation:


P. umbrosus should have dark edges on the gills.

does this species have marginate gills? I thought it did not
