Amanita muscaria var. formosa


Amanita muscaria var. formosa, known as the yellow orange fly agaric, is a poisonous 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. American mycologist Harry D. Thiers described a yellow-capped taxon that he called var. formosa from the United States, but it is not the same as the European variety.

Controversy

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. Amanita muscaria var. formosa has been described as 'Amanita muscaria var. guessowii'.
