Four strains of anamorphic yeasts isolated from the fruiting bodies of mushrooms collected in Taiwan were found to represent two novel yeast species belonging to the genus , which was formally known as the clade. Strains NY13M09 and NY14M14 were related to the type strains of , , and , and strains GG4M07 and GG6M14 were related to NRRL Y-17087 and NRRL Y-27777. However, strains NY13M09 and NY14M14 differed from their closest phylogenetic neighbours by 2.9-3.7 % in the D1/D2 domain sequence of the LSU rRNA gene and by 6.6-13.7 % in the internal transcribed spacer (ITS); GG4M07 and GG6M14 differed from their closest known species by 2.4 % in the D1/D2 domain sequence of the LSU rRNA gene and by 8.7-10.0 % in the ITS. Meanwhile, these strains were also clearly distinguished from their closest relatives based on the results of physiological tests. Based on the characteristics described above, the strains could be regarded as representing two novel species of the genus , for which the names sp. nov. and sp. nov. are proposed. The holotypes are BCRC 23475 and BCRC 23476.
从台湾采集的蕈类果实中分离出的四株异形酵母菌株被发现代表了两个属于的新酵母物种，该属以前被称为 分支。菌株 NY13M09 和 NY14M14 与 、 、 和 的模式菌株有关，而菌株 GG4M07 和 GG6M14 则与 NRRL Y-17087 和 NRRL Y-27777 有关。然而，菌株 NY13M09 和 NY14M14 与其最接近的系统发育邻居在 LSU rRNA 基因的 D1/D2 结构域序列上的差异为 2.9-3.7%，在内部转录间隔区（ITS）上的差异为 6.6-13.7%；菌株 GG4M07 和 GG6M14 在 LSU rRNA 基因的 D1/D2 结构域序列上的差异为 2.4%，在 ITS 上的差异为 8.7-10.0%。同时，这些菌株在生理测试的结果也与它们最接近的已知物种明显不同。基于上述特征，这些菌株可以被视为代表的两个新种，分别命名为 sp. nov. 和 sp. nov.。其模式菌株为 BCRC 23475 和 BCRC 23476。
