Three strains were isolated from the nostrils of a koala and the surrounding environment in a Japanese zoological park. Sequence analysis of the nuclear rDNA internal transcribed spacer (ITS) region and the large subunit rDNA D1/D2 domains in addition to physiological and morphological studies indicated that the isolates represent a single novel species belonging to the basidiomycetous genus Cryptococcus (Tremellales, Tremellomycetes, Agaricomycotina). Phylogenetic analysis based on D1/D2 and ITS regions revealed that the novel species belongs to the Fuciformis clade. The name Cryptococcus yokohamensis sp. nov. is proposed to accommodate these isolates with strain JCM 16989(T) (=TIMM 10001(T)=CBS 11776(T)=DSM 23671(T)) as the type strain.

In this study, white jelly mushrooms that were collected in Tottori Prefecture, Japan, were identified as by phylogenetic analysis of the rDNA-ITS region. Fluorescent microscopic analysis using 4',6-diamidino-2-phenylindole staining to visualize the nuclei in each cell revealed that basidiospores isolated from the fruiting body were monokaryotic. Furthermore, monokaryotic yeasts were germinated from these basidiospores and the resulting crossed mycelium was dikaryotic and bore clamp cells, suggesting a heterothallic lifecycle for this species.
