Five yeast strains were isolated from rotting wood samples collected in the Xishuangbanna Tropical Rainforest, Yunnan Province, PR China. Phylogenetic analysis of the D1/D2 domains of the large subunit rRNA gene indicated that these strains represent two novel species of the genus sp. nov. produces one to two spherical ascospores per ascus, and is most closely related to and sp. nov. differed from the type strains of the two latter species by 13-24 substitutions in the D1/D2 domains and by 39-56 substitutions in the ITS regions. f.a., sp. nov. is a member of the subclade, but the formation of ascospores was not observed on various sporulation media. sp. nov. differed from other members of the subclade by 23-26 substitutions in the D1/D2 domains and by more than 67 substitutions in the ITS regions. The holotype of sp. nov. is NYNU 17944 (CBS 15232) and the holotype of sp. nov. is NYNU 18913 (CBS 16054).
从中国云南省西双版纳热带雨林中采集的腐烂木材样本中分离出了 5 株酵母菌株。对大亚基 rRNA 基因的 D1/D2 结构域的系统发育分析表明，这些菌株代表了属的两个新种。种。nov. 每个子囊产生 1 到 2 个球形子囊孢子，与和种。nov. 最接近。种。nov. 与后两个种的模式株在 D1/D2 结构域有 13-24 个取代，在 ITS 区有 39-56 个取代。f.a.，种。nov. 是亚分支的成员，但在各种产孢培养基上都没有观察到子囊孢子的形成。种。nov. 与亚分支的其他成员在 D1/D2 结构域有 23-26 个取代，在 ITS 区有超过 67 个取代。种。nov. 的模式标本是 NYNU 17944（CBS 15232），种。nov. 的模式标本是 NYNU 18913（CBS 16054）。
