Amanita muscaria var. formosa

Amanita muscaria var. formosa is a basidiomycete fungus of the genus Amanita. This variety, which can be distinguished from 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.
