"And remember to first identify Amanita muscaria from its more deadly relatives, A. phalloides, A. ocreata, A. virosa, and A. verna, before gathering on your own. Each of these potentially deadly species can be differentiated from A. muscaria by their saclike volva. If you have any doubt whatsoever about the mushroom you have then discard it."

Erowid Psychoactive Amanitas Vault
As I've said before, unless you have a degree or a fairly large amount of experience in the field, do *not* go mushroom hunting. I actually have mushrooms growing in my backyard right now that are almost definitely amanitas, but I can't tell if they're pantherina or phalloides, and becuase of this they will continue to grow unmolested.
