Abstract

Species classified in Cordycipitaceae (Hypocreales) include multiple entomopathogenic fungi. Numerous changes have recently occurred in the nomenclature of cordycipitaceous fungi due to the single naming system proposed for pleomorphic fungi in 2011. Species of Cordycipitaceae are widely applied as herbal medicines, especially in Asian cultures. However, the diversity of Cordycipitaceae in Taiwan is based on relatively few literature records. Here we conducted a comprehensive survey of this family throughout the island of Taiwan and provided a glimpse of the diversity and distribution patterns. In addition, the present study reassesses the generic and species boundaries of Cordycipitaceae and finally provides an updated phylogenetic overview of Cordyceps and allied genera. Phylogenetic reconstructions using combined ITS, nrLSU, tef1-α, rpb1, and rpb2 sequence data, along with morphological features, resulted in 10 novel species: Akanthomyces taiwanicus sp. nov., Blackwellomyces taiwanensis sp. nov., Cordyceps hehuanensis sp. nov., C. locastrae sp. nov., C. malleiformis sp. nov., C. pseudorosea sp. nov., C. siangyangensis sp. nov., Samsoniella lasiocampidarum sp. nov., S. yuanzuiensis sp. nov., and Simplicillium salviniae sp. nov.; and nine new records for Taiwan: A. kanyawimiae, A. muscarius, S. cardinalis, S. hepiali, B. lii, B. medogensis, C. lepidopterorum, C. neopruinosa, and Si. chinense. Furthermore, we provided DNA sequence data of the ex-type strains of C. ninchukispora for the first time and determined the species limits of the taxon. In addition, the present study proposed to synonymize B. staphylinidicola and C. jakajanicola under B. bassiana and C. lepidopterorum, respectively. Moreover, three species, C. roseostromata, C. kyushuensis, and C. shuifuensis, that clustered within the species clade of C. militaris are proposed to be synonymized under the latter taxon. To maintain the monophyly of Cordyceps, we propose to classify Parahevansia koratensis in Cordyceps, which makes the genus Parahevansia obsolete.

台湾冬虫夏草属物种的系统发育多样性及形态特征。

虫草科的物种包括多种昆虫病原真菌。由于2011年提出了多形性真菌的单一命名系统，最近在虫草科真菌的命名法上发生了许多变化。冬虫夏草科植物被广泛用作草药，特别是在亚洲文化中。台湾冬虫夏草科植物的多样性，文献记载较少。在此，我们对整个台湾岛的这个科进行了全面的调查，并提供了一个多样性和分布模式的一瞥。此外，本研究重新评估了虫草科的属和种边界，最后提供了虫草及其近缘属的最新系统发育概述。利用ITS、nrLSU、tef1-α、rpb1和rpb2序列数据，结合形态特征进行系统发育重建，获得10个新种：台湾赤霉、台湾黑wellomyces、河环虫草、locastrae、malleiformis、pseudorosea、香阳虫草、lasiocamidarum、S. yuanzuiensis、Simplicillium salviniae；台湾新记录9种：肯雅维蠓、muscarius蠓、红衣蠓、hepiali蠓、lii蠓、medogensis蠓、鳞翅目蠓、neopruinosa蠓、Si。摘要。此外，我们首次提供了C. ninchukispora前型菌株的DNA序列数据，并确定了该分类单元的种限。此外，本研究还建议将金黄色葡萄球菌和jakajanicola分别归类于球孢白僵菌和鳞翅目白僵菌。此外，本研究还认为，属于军蛾种分支的3个种，即蔷薇C. roseostromata、九州C. kyushuensis和水富C. shuufuensis，在后者的分类群中具有同义性。为了保持冬虫夏草的单系性，我们建议将冬虫夏草属（Parahevansia koratensis）分类在冬虫夏草中，从而使Parahevansia属被淘汰。分类新异：新种：台湾Akanthomyces Chuang， B.

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.
