Observation 50082: Agaricus L.
When: 2010-08-08
Who: wbwarner
No herbarium specimen

Notes: Sorry for the cruddy specimen in the pic—I did not take a pic in the field (habitat was mixed ponderosa pine, juniper, and oak), but the cap was about 8-9" across before it started to dry (in field (mature): free, dark chocolate colored gills & spore print, smooth stipe (very slight indication of a few scales under the scope) with thin annulus (can’t remember if it was skirt like, but specimen was bouncing around in the back of the truck for the day upside down and the annulus had “wilted” towards pileus), stipe ~~5" from substrate to pileus, weakly blushing red-brown (not yellow) upon rubbing (top of stipe in pic was rubbed), odor very mild “Agaricus bisporus-like.” I found a perfectly “normal” Agaricus augustus button about 200 yards away the day before (as well as another (smaller, thinner, non-staining, mild odor) Agaricus sp. with a gestalt similar to A. silvestris). In the field this was a large, heavy, thick-fleshed and impressive mushroom. Given its size & stature I am hoping someone might have an idea as to species?
