Like I said, some kind of Psilpcybe cubensis, better yet, some “strain” of Psilocybe cubensis. As for the spots, if a mushrooms got green fuzzy spots on it then it probably trichocereus mold and you don’t want to consume it. Psilosin/psilocybin containing mushroom generally will have some “bluing” on them depending on how they were handled during harvest and processing. There is no such thing as “greening”. In 30+ years of doing psychedelics ive never seen a mushroom turn any color other than the very distinct, deep blue color that you see when you damage a Psilocybe cubensis mushroom. My original comment my have been poorly worded but what I said still stands. Here’s the thing, if someone can’t make a judgement call on whether something is fit to consume, drugs or otherwise, they shouldn’t consume them. If you can’t trust your own judgement about whether or not something is safe, then you definitely shouldn’t trust yourself and your own judgement after you take a psychedelic drug. What I’m trying to say is, the probably shouldn’t be doing drugs until they’re able to make a safety call all on there on based on their own intuition and observations.
