If you want to try amanita muscaria as a hallucinogen, make _sure_ you know how to identify it. One of the key identifying features is the base of the stem; if there is a uniform cup-like sheath on the base of the stem, it's not a. muscaria. A. muscaria has layers of shaggy membrane at the bottom of the stem, not a single cup. Some of the amanita lookalikes can make you very sick, although I don't think there are any deadly mushrooms that you could readily mistake for a. muscaria. But do some studying and learn what you're doing if you're going to consider eating wild mushrooms.
Also, don't eat amanitas raw. The best way to dose with them is to desiccate them in an oven, then grind them into a powder, then use the powder to make a tea and drink it. The heat will convert the ibotenic acid in the mushrooms, which will sicken you, into muscimol, the hallucinogenic chemical that they're known for.
