Abstract

The family Plectosphaerellaceae (Glomerellales, Sordariomycetes) includes numerous plant pathogenic genera and soil-borne fungal species. Ten genera are currently accepted, including several taxa that occupy an unresolved position within the family. To address this issue, a multilocus sequence analysis was carried out using partial gene sequences from the 28S large subunit nrRNA gene (LSU), the internal transcribed spacer (ITS) regions of the nrDNA region, including the 5.8S nrRNA gene, the translation elongation factor 1-alpha (TEF1-α), tryptophan synthase (TS), actin (ACT) and the RNA polymerase II second largest subunit (RPB2), based on a large set of isolates mainly from the CBS collection. Results of the molecular data combined with a detailed morphological study resolved 22 genera in the family, of which 12 are newly described. Additionally, 15 new species and 10 new combinations are proposed. An epitype and neotype are also introduced for Stachylidium bicolor and Plectosphaerella cucumerina, respectively.

Plectosphaerellaceae (Glomerellales, Sordariomycetes)包括许多植物病原属和土壤传播的真菌物种。目前被接受的有10个属，包括几个分类群，它们在这个科中占据一个未解决的位置。为了解决这一问题，基于主要来自CBS收集的大量分离物，利用28S大亚基nrRNA基因(LSU)的部分基因序列、nrDNA区域的内部转录间隔区(ITS)区域(包括5.8S nrRNA基因)、翻译延伸因子1-α (TEF1-α)、色氨酸合成酶(TS)、肌动蛋白(ACT)和RNA聚合酶II第二大亚基(RPB2)的基因序列进行了多位点序列分析。分子数据结合详细的形态学研究结果确定了该科22个属，其中12个为新描述。此外，还提出了15个新种和10个新组合。并分别介绍了双色葡萄球菌和黄瓜球孢的表型和新型。

期刊介绍： The international journal Studies in Mycology focuses on advancing the understanding of filamentous fungi, yeasts, and various aspects of mycology. It publishes comprehensive systematic monographs as well as topical issues covering a wide range of subjects including biotechnology, ecology, molecular biology, pathology, and systematics. This Open-Access journal offers unrestricted access to its content. Each issue of Studies in Mycology consists of around 5 to 6 papers, either in the form of monographs or special focused topics. Unlike traditional length restrictions, the journal encourages submissions of manuscripts with a minimum of 50 A4 pages in print. This ensures a thorough exploration and presentation of the research findings, maximizing the depth of the published work.
