Amanita muscaria var. formosa

Amanita muscaria var. formosa, known as the yellow orange fly agaric, is a hallucinogenic and 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. The Amanita Muscaria is native to temperate or boreal forest regions of the Northern Hemisphere. However, it has also been introduced in New Zealand, Australia, South America, and South Africa....read more on Wikipedia.
