Abstract

Four new Keratinophyton species (Ascomycota, Pezizomycotina, Onygenales), K. gollerae, K. lemmensii, K. straussii, and K. wagneri, isolated from soil samples originating from Europe (Austria, Italy, and Slovakia) are described and illustrated. The new taxa are well supported by phylogenetic analysis of the internal transcribed spacer region (ITS) region, the combined data analysis of ITS and the nuclear large subunit (LSU) rDNA, and their phenotype. Based on ITS phylogeny, within the Keratinophyton clade, K. lemmensii is clustered with K. durum, K. hubeiense, K. submersum, and K. siglerae, while K. gollerae, K. straussii and K. wagneri are resolved in a separate terminal cluster. All four new species can be well distinguished from other species in the genus based on phenotype characteristics alone. Ten new combinations are proposed for Chrysosporium species which are resolved in the monophyletic Keratinophyton clade. A new key to the recognized species is provided herein.

角藻的分子系统学:原属黄孢属的种的包括和四个新种的描述。

描述并说明了从欧洲(奥地利、意大利和斯洛伐克)土壤样品中分离到的4个角藻新种(子囊菌门、Pezizomycotina、Onygenales)、K. gollerae、K. lemmensii、K. straussii和K. wagneri。内部转录间隔区(ITS)区域的系统发育分析、ITS与核大亚单位(LSU) rDNA的联合数据分析及其表型均为新分类群提供了良好的支持。基于ITS系统发育，在角生植物分支中，lemmensii与durum K.、hubeiense K.、undersum K.和siglerae K.聚集在一起，而K. gollerae、K. straussii和K. wagneri被分解在一个单独的末端集群中。这四个新种都可以根据表型特征与属内其他物种区分开来。在单系角朊菌支系中，提出了10个新组合。本文提供了一种新的识别种的密钥。

期刊介绍： The flagship journal of the International Mycological Association. IMA Fungus is an international, peer-reviewed, open-access, full colour, fast-track journal. Papers on any aspect of mycology are considered, and published on-line with final pagination after proofs have been corrected; they are then effectively published under the International Code of Nomenclature for algae, fungi, and plants. The journal strongly supports good practice policies, and requires voucher specimens or cultures to be deposited in a public collection with an online database, DNA sequences in GenBank, alignments in TreeBASE, and validating information on new scientific names, including typifications, to be lodged in MycoBank. News, meeting reports, personalia, research news, correspondence, book news, and information on forthcoming international meetings are included in each issue
