本研究采自贵州、海南、云南等地的喀斯特地区，采集了该科真菌标本。形态分子分析证实，这些新标本包括一个新属Pseudodiatrype，三个新种Diatrypelancangensis，Diatrypellaperidooregonensis和Eutypacerasi，一个新组合Diatrypellaoregonensis，两个中国新记录种Allodiatrypethailandica和Diatrypellavulgaris，以及另外两个已知种Neoeutypellabaoshanensis和Paraeutypellacitricola。根据多基因系统发育分析（ITS、β-微管蛋白）以及形态学分析介绍了新的分类群。新属Pseudodiatrype的特征是其疣状的子座，其中5-20个子囊浸入一个子座中，并且内子座由薄的黑色大白色细胞的外层和内层组成，其中薄的粉状淡黄色细胞。这些特征将该属与两个相似的属Allodiatrype和Diatrype分开。根据形态学和系统发育学分析，将Diatrypelancangensis作为Diatrype的一个新种引入。Diatrypelancangensis的子座与D.subundulata和D.undulate相似，但子囊孢子较大。根据系统发育分析，Diatrypeoregonensis被归为Diatrypella属，命名为Diatrypellaoregonensis，而Diatrypellapulgodoregonensis则被引入为Diatrypella属的一个新种，每个孢子中有8个孢子。此外，多基因系统发育分析表明，Eutypacerasi与宽肠球菌亲缘关系较近，但Eutypacerasi的子囊和子囊较小。本文讨论了囊孢科某些属的多系性，导致该科的分类混乱，并讨论了是否仍可用每个子囊的子囊孢子数作为分类依据。
In this study, fungal specimens of the family Diatrypaceae were collected from karst areas in Guizhou, Hainan and Yunnan Provinces, China. Morpho-molecular analyses confirmed that these new collections comprise a new genus Pseudodiatrype, three new species (Diatrypelancangensis, Diatrypellapseudooregonensis and Eutypacerasi), a new combination (Diatrypellaoregonensis), two new records (Allodiatrypethailandica and Diatrypellavulgaris) from China and two other known species (Neoeutypellabaoshanensis and Paraeutypellacitricola). The new taxa are introduced, based on multi-gene phylogenetic analyses (ITS, β-tubulin), as well as morphological analyses. The new genus Pseudodiatrype is characterised by its wart-like stromata with 5–20 ascomata immersed in one stroma and the endostroma composed of thin black outer and inner layers of large white cells with thin, powdery, yellowish cells. These characteristics separate this genus from two similar genera Allodiatrype and Diatrype. Based on morphological as well as phylogenetic analyses, Diatrypelancangensis is introduced as a new species of Diatrype. The stromata of Diatrypelancangensis are similar to those of D.subundulata and D.undulate, but the ascospores are larger. Based on phylogenetic analyses, Diatrypeoregonensis is transferred to the genus Diatrypella as Diatrypellaoregonensis while Diatrypellapseudooregonensis is introduced as a new species of Diatrypella with 8 spores in an ascus. In addition, multi-gene phylogenetic analyses show that Eutypacerasi is closely related to E.lata, but the ascomata and asci of Eutypacerasi are smaller. The polyphyletic nature of some genera of Diatrypaceae has led to confusion in the classification of the family, thus we discuss whether the number of ascospores per asci can still be used as a basis for classification.
