is a discomycetous genus belonging to the family Helotiaceae (Helotiales). The genus currently comprises 19 species. Among them, 17 species have been reported from Asia, of which 14 were reported from China. During a survey of Leotiomycetes, we collected six specimens of species from southwest China and northern Thailand. The samples were examined based on the phylogenetic analyses of LSU and ITS sequence data, along with morphological characterization, and our results demarcate three new species, viz., , and . formed a distinct clade closely related to , and , whereas clustered closer to with 100% ML and 1.00 BIPP statistical support. All three species have similar apothecia sizes but differ in their coloration. has aseptate ascospores, while and have 7-septate ascospores. The paraphyses in are branched, while they are unbranched in the other two species. An updated key to the known species of is also provided.
是一个盘菌属，隶属于柔膜菌科（柔膜菌目）。该属目前包含19个物种。其中，17个物种已在亚洲被报道，其中14个在中国被报道。在对散囊菌纲的调查中，我们从中国西南部和泰国北部采集了该属物种的六个标本。基于LSU和ITS序列数据的系统发育分析以及形态特征对样本进行了检查，我们的结果划分出三个新物种，即， 、 和 。 形成了一个与 、 和 密切相关的独特分支，而 在100%的最大似然法和1.00的贝叶斯后验概率统计支持下更靠近 聚类。所有这三个物种的子囊盘大小相似，但颜色不同。 有无隔的子囊孢子，而 和 有7隔的子囊孢子。 的侧丝是分枝的，而其他两个物种的侧丝是不分枝的。还提供了该属已知物种的更新检索表。
