Amanita muscaria var. formosa is common in deciduous and coniferous forests of northeast North America. Known for its fly-killing properties, the major toxins involved in poisoning are muscimol (3-hydroxy-5-aminomethyl-1-isoxazole, an unsaturated cyclic hydroxamic acid) and ibotenic acid. Muscimol is the product of the decarboxylation of ibotenic acid. You may probably recognize the red version of this mushroom in the famous video game series Super Mario Bros.
