This genus is responsible for approximately 95% of the fatalities resulting from mushroompoisoning, with the death cap accounting for about 50% on its own. The most potent toxin present in these mushrooms is amanitin, of which at least eight versions are known.
Amanita muscaria, commonly known as the fly agaric, is a psychoactivefungus. It is known as the fly agaric for its ability to kill houseflies when combined with milk. The reason for this is that flies are attracted to the milk because it is so sweet. When they drink the milk they feel the effects of the mushroom and begin to get intoxicated.
