Notes on Dipodascus, Endomyces and Geotrichum with the description of two new species

The genus Endomyces is restricted to E. decipiens Reess, characterized by asci formed directly on hyphae and hat-shaped ascospores. The species forming asci from conjugating gametangial cells and having ellipsoidal ascospores are transferred to Dipodascus. A strain isolated from cladodes of Opuntia in Australia is described as Dipodascus australiensis von Arx et Barker and strains isolated from Armillaria mellea are classified as Geotrichum armillariae von Arx.
