 The family Hygrophoraceae was first proposed by Dutch botanist Johannes Paulus Lotsy (1907) to accommodate agarics with thick, waxy lamellae (gills) and white spores.Lotsy's concept of the family included not only the waxcap-related genera "Hygrophorus", "Hygrocybe", "Camarophyllus" (= "Hygrophorus"), and "Godfrinia" (= "Hygrocybe"), but also "Gomphidius" (despite its blackish spores) and "Nyctalis" (= "Asterophora").Not all subsequent authors accepted the Hygrophoraceae; Carleton Rea (1922), for example, continued to place these genera within a widely defined Agaricaceae.
