Amanita chrysoblema, with the common name American fly agaric, white variant, is a basidiomycete fungus of the genus Amanita. Although named chrysoblema, it is traditionally thought to be an Amanita muscaria variant, a group of fungi commonly known as fly agarics. A. chrysoblem is an uncommon fungus, distinguishable by an off-white to silvery-white cap with white warts. The cap has cuts on the side, but is otherwise similar to the usual fly agaric form. The fungi is poisonous due to high levels of ibotenic acid and muscimol.
