When culturing the pileitrama of young fruit bodies of the two mycoparasitic agarics, Asterophora lycoperdoides (Bull.: Fr.) Ditmar and A. parasitica (Bull.: Fr.) Singer, two tremelloid yeasts were detected (Laaser et al., 1988, 1989; Prillinger, 1987a). The term tremelloid was suggested by Oberwinkler (Laaser et al., 1988; Oberwinkler pers. comm.) for budding yeasts having a cup-shaped parenthesom. The yeasts appeared infrequently after 8–16 days in axenic cultures on different media. With A. lycoperdoides the isolation procedure was successfully repeated in the following years, leading to yeast strains from three different localities in Bavaria, Germany. In subcultures of the original yeast isolates from both species, Asterophora fruit bodies developed after 4–6 weeks (Prillinger, 1986). Attempts to isolate yeasts from Asterophora chlamydospores of artificially grown fruit bodies were successful in our first A. lycoperdoides mycelial strain (Prillinger, 1986). The yeast isolates of the two agarics A. lycoperdoides Asterotremella gen. nov. albida, an anamorphic tremelloid yeast isolated from the agarics Asterophora lycoperdoides and Asterophora parasitica
