A new species of was isolated from fruiting bodies of the wood-decaying fungus collected from Kyoto, Japan. Attempts to culture it using bacteria, yeast, and freeze-killed wax moth larvae as food or substrate failed. The eurystomatous form of the species was not found in the collected material, and the species is typologically characterized by: its 'small' stoma with thin, membrane-like cheilostomatal plates, a small triangular right subventral tooth, thorn-like dorsal tooth, and small left subventral denticles; a short, blunt male tail spike; and a short, conical female tail. Although the posterior probability support was not high (66%), phylogenetic analysis of both small and large ribosomal RNA gene subunits suggests that the species is closely related to and . . The new species can be distinguished from those two by its diagnostic characters comprising the stomatal morphology and male and female tail characters.
从日本京都采集的木腐真菌子实体中分离出一种新物种。尝试以细菌、酵母和经冷冻处理的蜡螟幼虫作为食物或底物来培养该物种，但均告失败。在所采集的材料中未发现该物种的宽口形态，该物种在形态学上的特征为：其“小”气孔具薄的、膜状的唇口板，一个小的三角形右腹下齿、刺状背齿以及小的左腹下小齿；雄性尾突短且钝；雌性尾部短且呈圆锥形。尽管后验概率支持度不高（66%），但对小核糖体RNA基因亚基和大核糖体RNA基因亚基的系统发育分析表明该物种与[具体物种1]和[具体物种2]密切相关。该新物种可通过其包括气孔形态以及雄性和雌性尾部特征在内的诊断特征与那两个物种区分开来。
