(Cytosporaceae, Diaporthales) is a fungal genus that usually inhabits plants as endophytes, saprobes, as well as pathogens. Species of this genus are characterized by possessing allantoid hyaline conidia and ascospores. Samples with typical Cytospora canker symptoms on , and sp. were collected in Tibet and Xinjiang, China. Species were identified using both morphological and molecular approaches of combined loci of internal transcribed spacer region rDNA (ITS), the partial actin () region, RNA polymerase II second largest subunit (), the translation elongation factor 1-alpha () gene and the partial be-ta-tubulin () gene. Six isolates in the present study formed three distinct clades from previously known species. sp. nov. from sp., sp. nov. from and from were proposed herein. The current study improves the understanding of species concept in .
（间座壳科，座囊菌目）是一个真菌属，通常以内生菌、腐生菌以及病原菌的形式寄生于植物。该属物种的特征是具有腊肠形透明分生孢子和子囊孢子。在中国西藏和新疆采集了具有典型壳囊孢溃疡病症状的 、 和 种的样本。利用核糖体DNA内转录间隔区（ITS）、肌动蛋白（）区域部分序列、RNA聚合酶II第二大亚基（）、翻译延伸因子1-α（）基因以及β-微管蛋白（）基因部分序列的形态学和分子学联合方法对物种进行鉴定。本研究中的6个分离株与先前已知物种形成了3个不同的进化枝。本文提出了来自 种的 新种、来自 的 新种以及来自 的 。当前研究增进了对 属物种概念的理解。
