Is Magpie Inkcap edible?

Coprinopsis picacea is considered inedible due to its unpleasant taste and odor, and it is suspected to contain toxins that can cause gastrointestinal upset. While not as well-studied as Coprinopsis atramentaria (Common Inkcap) for its coprine content, it is generally advised against consumption. Some sources suggest it may contain coprine-like compounds, which would cause an Antabuse-like reaction when consumed with alcohol, similar to Coprinopsis atramentaria. However, this is not definitively confirmed for C. picacea. Regardless, its unpleasant characteristics make it unsuitable for culinary use.
