No specimen available

It keys to Pluteus cervinus in Arora. But it was found on June 16, 2009 in the Sierras. Mycologists I’ve talked to are suprised (skeptical of my determination?) that it is fruiting in spring. It was found on decaying wood in mixed conifer forest at 5600 feet elevation. Perhaps it is P. petasatus.

The Undescribed White Scaly Pluteus

This is one fairly common white, scaly Pluteus that in California circles goes for P. petasatus, but it is not. It fruits in the Sierra mountain range in the Spring. I have been tracking it for the past 2-3 years.


Haven’t seen anyone breaking legs to describe it formally. I keep my collections dry…

It’s not unusual

to find Pluteus species in spring as is the case with most of the wood-inhabiting fungi …

cap too pale for cervinus…

I’d call it petasatus. And what a weird brown sporeprint! Should be a dark fleshy pink…but the free gills are pinkish, and everything else fits for Pluteus.
