Amanita muscaria var. formosa, known as the yellow orange fly agaric, is a poisonous[1] basidiomycete fungus of the genus Amanita. This variety, which can sometimes be distinguished from most other A. muscaria by its yellow cap, is a European taxon, although several North American field guides have referred A. muscaria var. guessowii to this name.[2] American mycologist Harry D. Thiers described a yellow-capped taxon that he called var. formosa from the United States,[3] but it is not the same as the European variety.


Recent DNA evidence has shown Amanita muscaria var. formosa to be a distinct species from Amanita muscaria and it will be getting its own species status soon.[citation needed] Amanita muscaria var. formosa has been described as Amanita muscaria var. guessowii.[4]
