Remarks (internal):The genus Gloeocystidiellum is characterized by gloeocystidia and amyloid basidiospores but considerably varies in other morphological features such as texture of the basidiomata and ornamentation of the basidiospores. This genus has been recognized as a heterogeneous one by many mycologists, and the following genera have been segregated from Gloeocystidiellum: Boidinia Stalpers & Hjortstam (Hjortstam and Stalpers, 1982), Conferticium Hallenberg (Hallenberg, 1980), Megalocystidium Jülich, 1978) and Vesiculomyces Hagström (Hagström, 1977). According to Boidin and Lan­quetin (1983), Megalocystidium is a synonym of Vesiculomyces.
