, a new genus, is introduced with its type species, , which was isolated from withered twigs of two medicinal plants, (Blanco) Merr (Verbenaceae) and (Hook.f.) Ridl (Rubiaceae) in northern Thailand. The genus is characterized by mononematous, septate, brown or dark brown conidiophores, monotretic conidiogenous cells and catenate, obclavate, olivaceous to blackish brown conidia. Phylogenetic analysis of combined LSU, SSU, -α, and ITS sequence data showed forms a distinct phylogenetic lineage in Pleosporales, Dothideomycetes. Therefore, we treat as Pleosporales genera based on morphology and phylogenetic analyses. Descriptions and illustrations of the new taxa are provided, and it is compared with morphologically similar genera.
引入了一个新属及其模式种，该模式种是从泰国北部两种药用植物（马鞭草科的（布兰科）梅里尔和茜草科的（胡克.f.）里德尔）的枯枝中分离出来的。该属的特征是单丝、有隔膜、棕色或深棕色的分生孢子梗，单孔产孢细胞以及链状、倒棍棒形、橄榄色至黑褐色的分生孢子。对 LSU、SSU、-α、和 ITS 序列数据进行联合系统发育分析表明，在座囊菌纲格孢腔菌目中形成了一个独特的系统发育谱系。因此，基于形态学和系统发育分析，我们将视为格孢腔菌目属。提供了新分类群的描述和图示，并将其与形态相似的属进行了比较。
