I dont harvest Amanitas for food but I am looking for a fly agaric to mark it off my list. Fly Agarics are considered a good edible if you boil them and change the water. They have ibotenic acid and muscarine which are toxic. Alternatively if you dry them the ibotenic acid is converted to muscimol which is a psychoactive alkaloid. (I've read some eat them fresh, there is a lot of differing opinions on this mushroom.) Some people report it is pleasant, others have very negative reports. It is a different chemical from the typical magic mushrooms and considered not as desireable or safe. I have no interest in it for that. But it's very pretty nonetheless.
Fly Agaric (Amanita Muscaria)
Amanita Phalloides (Death Cap)
Amanita Virosa (Destroying Angel)
These two deadly mushrooms along with a few others give Amanita their bad reputation. Mushroom hunters are better off not touching this genus unless they have the training/experience to do so safely.
