Paxillus involutus is a large brown mushroom, ranging from 3" to 7" wide, recognized by a broadly depressed cap, inrolled cap margin from which the species name and common name is derived. The stem is stout and lumpy honeycomb gills with the tendency for all parts of the mushroom to bruise brown. The gills are also easily peeled from the cap and sometimes...

Occurs in the optical dextrorotatory form [aJo +31.9° (C2H5OH) in the gasteromycete Chamonixia caespitosa (Basidiomycetes) and is responsible for the intense blue color of bruises on the white sporophore. The (- )-enantiomer is isolated from Gyrodon lividus and Paxillus involutus (Basidiomycetes) see also gyrocyanin and involutin.
