shaggy ink cap, lawyer's wig, or shaggy mane

Notes:

When young it is an excellent edible mushroom provided that it is eaten soon after being collected (it keeps very badly because of the autodigestion of its gills and cap). If long-term storage is desired, sauteing or simmering until done will allow the mushrooms to be stored in a refrigerator for several days or frozen. Processing must be done whether for eating or storage within four to six hours of harvest to prevent undesirable changes to the mushroom. The species is cultivated in China as food.. ---> The agent responsible for unpleasant symptoms when consumed with alcohol, coprine, which is found in Coprinopsis atramentaria, has not been isolated from C. comatus
