Look out for indications of mould. If you see any eco-friendly mildew, white fuzzy mold, or dim black places (mildew) within the mushroom, usually do not consume it. Don’t fear if you see blue staining—this is popular in Psilocybe mushrooms and an indicator that the mushrooms include psilocybin.  Ms Rigby https://psychedelicfarmmeds.com/product/alice-mushroom-chocolate-uk/
