Six collections of ascomycetes were obtained from samples collected from dead branches and leaves of in Guizhou and Yunnan provinces, China. By incorporating multigene phylogenetic analysis (ITS, LSU, , SSU, , ) supplemented by morphological data, we establish two novel species, namely and . In morphology, can be distinguished from by its narrower conidia (13-16 µm vs. 27.3-35.5 µm), and is characterized by black, globose conidia (16.2 × 14.4 µm). The phylogenetic results further substantiated them as novel taxa. The present study contributes to our comprehension of the range of fungi found in , thereby expanding our knowledge of the diversity of fungi within this host.
从中国贵州和云南省的枯枝落叶样本中获得了六组子囊菌。通过整合多基因系统发育分析（ITS、LSU、 、SSU、 、 ）并辅以形态学数据，我们建立了两个新物种，即 和 。在形态上， 与 的区别在于其分生孢子较窄（13 - 16微米对27.3 - 35.5微米），并且 以黑色、球形分生孢子（16.2×14.4微米）为特征。系统发育结果进一步证实它们为新分类群。本研究有助于我们理解 在 中发现的真菌范围，从而扩展我们对该宿主内真菌多样性的认识。
