Observation 46573: Pluteus petasatus (Fr.) Gillet
When: 2010-06-08
No herbarium specimen

Notes: I had IDed petasatus once before… about 20 years ago. The ones I found at that time grew on wood chips in ornamental gardens on the campus of Binghamton University (formerly SUNY Binghamton). Those looked very much like the ones pictured in Arora… thick stalks and kinda squat. Except for the prominent brown scales on the caps, they were completely white. This latest find (posted here) is a virtual match for the petasatus pictured/described on Mushroom Expert. Makes me wonder if there’s more than one species included under the name petasatus.

These mushrooms have the pale appearance

and the fused stalk bases that are are common traits for petasatus. A darker Pluteus which are likely specimens of P. cervinus have appeared in the exact same spot as these… but without fused stalk bases. Maybe two different Pluteus species are growing from the same old buried tree stump? In light of the more recent Pluteus fruiting, it’s difficult to rule out the possibility that the ones seen here are pale version of cervinus. These (46573) were very pale from the first day that they appeared on my lawn… so I tend to think “petasatus.”
