and are genera in Bionectriaceae, and known in sexual perithecial ascomata and hyphomycetous asexual morphs. In their asexual morph, both genera share similar morphology in conidiophores and conidiogenous cell characteristics but differ in the development of conidiophores. The members of are distributed worldwide with the majority occurring in the tropics and the species are commonly reported as soil-borne fungi but also reported as endophytes, epiphytes, and saprotrophs. During a microfungi survey in Xizang, China, six collections of fresh and healthy and leaves were obtained. The taxonomy of these collections was investigated through a combination of morphological analysis and multigene phylogenetic analysis using Maximum likelihood and Bayesian inference. The newly generated sequences were clustered within and , showing hyphomycetes asexual morph. The results revealed three new species viz, , , and . This research sheds light on the overlooked fungal diversity in Xizang, China, expanding the known fungal biodiversity in the region. Additionally, two new combinations, and for and , and one synonymy, for are established, respectively.
[属名1]和[属名2]属于肉座菌科，以有性的子囊壳和丝孢菌无性形态而闻名。在它们的无性形态中，这两个属在分生孢子梗和产孢细胞特征方面具有相似的形态，但在分生孢子梗的发育上有所不同。[属名1]的成员分布于世界各地，大多数出现在热带地区，该属物种通常被报道为土传真菌，但也有报道称其为内生菌、附生菌和腐生菌。在中国西藏进行微真菌调查期间，获得了六份新鲜健康的[植物名称1]和[植物名称2]叶片样本。通过形态学分析和使用最大似然法和贝叶斯推断的多基因系统发育分析相结合的方法，对这些样本进行了分类研究。新生成的序列聚类在[属名1]和[属名2]内，显示出丝孢菌无性形态。结果揭示了三个新的[属名1]物种，即[物种名1]、[物种名2]和[物种名3]。这项研究揭示了中国西藏被忽视的真菌多样性，扩大了该地区已知的真菌生物多样性。此外，还分别建立了两个新组合，即将[组合前名称1]和[组合前名称2]分别组合为[组合后名称1]和[组合后名称2]，以及一个同义名，即将[同义前名称]定为[同义后名称]。
