Species of fungus
From Wikipedia, the free encyclopedia
Cortinarius smithii, also known as the western red dye mushroom, is an agaric fungus of the genus Cortinarius. Originally named Cortinarius phoeniceus var. occidentalis by American mycologist Alexander H. Smith in 1939, it was renamed to honor Smith in 2012,[2] after molecular analysis revealed that it was genetically different from Cortinarius phoeniceus. It is found in North America.[1]
