Naming
It was first described as ''Agaricus pediades'' by Swedish mycologist Elias Magnus Fries in 1821, and moved to its current genus ''Agrocybe'' by Victor Fayod in 1889. A synonym for this mushroom is ''Agrocybe semiorbicularis''.Some experts divide Agrocybe pediades into several species, mainly by habitat and microscopic features, such as spore size. It is recognized by the large, slightly compressed basidiospores with large central germ-spore, 4-spored basidia, subcapitate cheilocystidia and reare development of pleuro cystidia.
