 In the case of "Entoloma", the term refers to mushrooms with the hem turned inside.The name is derived from the Greek "entos" (ἐντός) meaning "inner" and "lóma" (λῶμα) meaning "fringe" from the in-rolled margin.The Swedish mycologist Elias Magnus Fries classified all pink-spored gilled fungi in a series "Hyporhodius" within his large genus "Agaricus", subdividing into five tribes based on cap shape, gills and size in 1821.
