Amanita chrysoblema

Amanita chrysoblema, with the common name American fly agaric, yellow/orange 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. chrysoblema has a cap that ranges from red to yellow to white. The cap may have grooves on its margins, and the cap often has an irregular pattern of universal veil remnants in the form of warts.

Furthermore, the base is bulbous and is encased by a volva. Multiple studded ridges are found as the base transitions to the stipe.

The fungus is poisonous due to high levels of ibotenic acid and muscimol.
