Avoid dangerous misidentification
Wild mushrooms should only be eaten when identification is certain. A review notes risks including look-alikes, contamination with toxic elements and very rapid spoilage.[1]
What about alcohol?
The well-known alcohol reaction is mainly associated with the common ink cap (Coprinopsis atramentaria) and coprine. Coprine has not been confirmed as a typical constituent of Coprinus comatus.[1]
Kitchen and storage
Shaggy manes are highly perishable and should be chilled, processed quickly and cooked thoroughly. Dark, liquefying specimens should not be eaten.
