摘要

蛇虫草属(Ophiocordyceps)是一种异质的、种类丰富的亚纲(Sordariomycetes, Ascomycota)属,包括无脊椎致病性分类群。本文报道了泰国产表皮虫草感染多种昆虫寄主(鳞翅目、半翅目)的7个新种:褐皮虫草、褐皮虫草、几何虫草、多皮虫草、少皮虫草、假针叶虫草和空间虫草。基于核糖体DNA大亚基(LSU)、延伸因子1- α (TEF)部分序列以及RNA聚合酶最大亚基和第二大亚基(RPB1, PRB2)的多基因位点的系统发育分析有力地支持了这些新种。它们与之前描述过的蛇虫草属(Ophiocordyceps acacularis)、O. atewensis、O. cochlidiicola和O. criinalis)的不同之处,在于其周皮、子囊孢子和分生孢子等特征的形状和大小。我们还报道了一份在泰国发现的大针叶虫新记录。

Ophiocordyceps is a heterogeneous, species-rich genus in the order Hypocreales (Sordariomycetes, Ascomycota) that includes invertebrate-pathogenic taxa. In this study, seven new species in Ophiocordyceps producing superficial perithecia infecting various insect hosts (Lepidoptera, Hemiptera) are described from Thailand – Ophiocordyceps brunneinigra, O. brunneiperitheciata, O. geometridicola, O. multiperitheciata, O. pauciovoperitheciata, O. pseudoacicularis and O. spataforae. Phylogenetic analyses based on multigene loci comprising the large subunit of the ribosomal DNA (LSU), partial sequences of elongation factor 1-alpha (TEF) and the largest and second largest subunit of the RNA polymerase (RPB1, PRB2) strongly support these new species of Ophiocordyceps in the Ophiocordycipitaceae. They differ from species previously described species Ophiocordyceps acicularis, O. atewensis, O. cochlidiicola, and O. crinalis, in the shape and sizes of distinguishing characters such as perithecia, ascospores and conidia. We also report a new record of O. macroacicularis in Thailand.

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.
