Clitocybe menthiodora

Clitocybe menthiodora is a species of mushroom-forming fungus first described by the Finnish mycologist Harri Harmaja in 1969. It is characterized by its dingy brown, hygrophanous cap, white spore print, and distinctive menthol-like odour in dried specimens, for which it is named.
