摘要

麦角菌(Clavicipitaceae,Hypocreales)于 1853 年被建立,尽管麦角菌在更长的时间内就已广为人知。到 2000 年,Claviceps 中已有约 70 个分类群被描述,其中 8 个种和 6 个变种是基于日本模式或真实标本。这些日本爪蟾分类群大多基于丢失的标本或无效名称,这意味着许多物种实际上只存在于科学文献中。这些物种的身份模糊不清,阻碍了姬蛙属分类学的研究。因此,我们寻找并采集了 300 多份新鲜标本,以寻找丢失的日本麦角。基于 LSU、TEF-1α、TUB2、Mcm7 和 RPB2 的 DNA 序列的多焦点系统发育分析揭示了日本标本与已知麦角属植物之间的系统发育关系,以及生物地理模式的存在。根据系统发育分析、寄主范围和形态学,我们重新评估了日本姬蛙,并确认日本至少有 21 个种。在这里,我们描述了 14 个以前描述过的类群的特征,并指定了 C. bothriochloae、C. imperatae、C. litoralis、C. microspora、C. panicoidearum 和 C. yanagawaensis 的新类型、变型和表型。Agropyri 和 C. kawatanii。提出并描述了六个新种:C. miscanthicola、C. oplismeni、C. palustris、C. phragmitis、C. sasae 和 C. tandae。新分类法:新物种:Claviceps miscanthicola E.

In search of lost ergots: phylogenetic re-evaluation of Claviceps species in Japan and their biogeographic patterns revealed.

Claviceps (Clavicipitaceae, Hypocreales) was erected in 1853, although ergotism had been well-known for a much longer time. By 2000, about 70 taxa had been described in Claviceps, of which eight species and six varieties were based on Japanese type or authentic specimens. Most of these Japanese Claviceps taxa are based on lost specimens or have invalid names, which means many species practically exist only in the scientific literature. The ambiguous identities of these species have hindered taxonomic resolution of the genus Claviceps. Consequently, we sought and collected more than 300 fresh specimens in search of the lost Japanese ergots. Multilocus phylogenetic analyses based on DNA sequences from LSU, TEF-1α, TUB2, Mcm7, and RPB2 revealed the phylogenetic relationships between the Japanese specimens and known Claviceps spp., as well as the presence of biogeographic patterns. Based on the phylogenetic analysis, host range and morphology, we re-evaluated Japanese Claviceps and recognised at least 21 species in Japan. Here we characterised 14 previously described taxa and designated neo-, lecto- and epi-types for C. bothriochloae, C. imperatae, C. litoralis, C. microspora, C. panicoidearum and C. yanagawaensis. Two varieties were elevated to species rank with designated neotypes, i.e. C. agropyri and C. kawatanii. Six new species, C. miscanthicola, C. oplismeni, C. palustris, C. phragmitis, C. sasae and C. tandae were proposed and described. Taxonomic novelties: New species: Claviceps miscanthicola E. Tanaka, Claviceps oplismeni E. Tanaka, Claviceps palustris E. Tanaka, Claviceps phragmitis E. Tanaka, Claviceps sasae E. Tanaka, Claviceps tandae E. Tanaka; New status and combination: Claviceps agropyri (Tanda) E. Tanaka, Claviceps kawatanii (Tanda) E. Tanaka; Typifications (basionyms): Lecto- and epitypification: Claviceps yanagawaensis Togashi; Neotypifications: Claviceps purpurea var. agropyri Tanda, Claviceps bothriochloae Tanda & Y. Muray, Claviceps imperatae Tanda & Kawat., Claviceps microspora var. kawatanii Tanda, Claviceps litoralis Kawat., Claviceps microspora Tanda, Claviceps panicoidearum Tanda & Y.

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.
