because it is not cubensis does not mean they are not pschoactive. There are hundreds of psylocybian mushrooms of low potency or very high.
also, few mushrooms are poisonous, as few are tasty.
still, even if you know exactly what you are doing you could get into trouble.
there are countless stories of knowledgeable folk getting sick or dying by accidentaly picking a companion species, picking in a region where they are inadequately prepared, mistaking one mushroom that looks like another in a different growth state and the like.
few but the most distinctive can be identified by pictures on the internet.
cubensis and azures are about the only two psychoactives I might hazard to identify that way.
boletus, shaggy manes and oysters are about the extent of the choice ones, maybe, maybe chanterelles.
