Foxyshaman - Amanita mushrooms are pretty much all poisonous, many of them are lethally so. I personally would not mess around with fly agarics. People who want a spiritual experience would probably be better off with liberty caps which a one of the sub-species of psilocybens. None of these fungus are particularly good for a human body.

I have something of an interest in mycology though that interest is in edibles like chantrelles, morels, chicken of the forest, etc.
