Three strains of a novel basidiomycetous yeast were isolated from the Xishuangbanna Tropical Rainforest, Yunnan Province, PR China. Sequence analysis of the D1/D2 domains of the large subunit (LSU) rRNA gene and the internal transcribed spacer (ITS) regions indicated that the novel species represents a member of the genus Vanrija. It differed from the most closely related known species, Vanrija albida CBS 2839 T , by 1.5 % sequence divergence (seven substitutions and two gaps out of 597 bp) in the D1/D2 domains and by 7.4 % sequence divergence (17 substitutions and 20 gaps over 495 bp) in the ITS regions, respectively. The three strains of the novel species reproduced asexually, and no mating could be found. In contrast to V. albida, the novel yeast species was able to assimilate d-glucosamine, inulin, erythritol and galactitol and unable to assimilate raffinose. The name Vanrija jinghongensis sp. nov. is proposed to accommodate these strains, with NYNU 17910 T (=CICC 33269=CBS 15229) as the type strain.
