Sporobolomyces bannaensis, a novel ballistoconidium-forming yeast species in the Sporidiobolus lineage.

Among ballistoconidium-forming yeast strains isolated from various plant leaves collected in Banna, Yunnan Province, China, five strains that formed pink-coloured colonies and asymmetric ballistoconidia were classified in a single group and assigned to the genus Sporobolomyces by conventional and chemotaxonomic studies. Analyses of the internal transcribed spacer region and 26S rDNA D1/D2 domain sequences indicated that these strains represent a novel species with a close phylogenetic relationship to Sporobolomyces blumeae in the Sporidiobolus lineage, for which the name Sporobolomyces bannaensis sp. nov. is proposed (type strain Y41(T)=AS 2.2285(T)=CBS 9204(T)).
