Key features
Cap gray-brown to ash-brown, covered with grayish, soft patches of veil that wash off easily; margin not striate. Stem white to grayish with a striate hanging ring and a bulbous, turnip-shaped base covered with concentric remnants of the volva; the flesh does NOT redden when cut, which distinguishes it from the blusher, and the absence of white warts distinguishes it from the Panthercap.
