Watch out for indications of mildew. If the thing is any eco-friendly mold, white fuzzy mold, or dark black spots (mildew) around the mushroom, don't consume it. Don’t be concerned if the thing is blue staining—this is prevalent in Psilocybe mushrooms and an indicator which the mushrooms consist of psilocybin.  https://socialmediastore.net/story19883224/psilocybin-chocolate-bar-usa-an-overview
