Proposed Names

29% (1)
Recognized by sight: Yellow, free gill attachment, growing on wood
29% (1)
Recognized by sight: The cap is the wrong color for P. romellii
Based on microscopic features: Spore size and shape matches. Perhaps pileipellis too. But many Pluteus probably share these features.

I did not make a spore print of this mushroom because it was dried by the time I got home. I am sure it is a Pluteus due to the substrate, free gills and microscopy.

so, microscopy

points in the direction of Pluteus in spite of such uncharacteristic gill color? what about spore color? was it pink?
