WTF, don't pick shrooms if you don't know anything about them. Do you know how many toxic mushrooms resemble various psychedelic/hallucinogenic species? Amanita muscaria, aka fly agaric, looks almost exactly like (and is in fact related to) A. phalloides, the death cap mushroom, which will do all kinds of bad shit to you and usually kills you. Think things like massive multiple organ failure.
