Abstract

An investigation of members of the soil keratinophilic fungi community in China resulted in the identification of one new monotypic genus, , and 10 new species, 2 of which are affiliated with , 1 with the new genus , 4 with , and 3 with . These novel taxa form an independent lineage distinct from other species, based on morphological and multilocus phylogenetic analyses. Descriptions, illustrations, and notes are provided for each taxon. These new taxa of the soil keratinophilic fungi add to the increasing number of fungi known from China, and it is now evident that numerous novel taxa are waiting to be described. Keratinophilic fungi are a group that can degrade and utilize keratin-rich material. It is also because of this ability that many taxa can cause infections in animals or humans but remain poorly studied. In this study, we reported a novel genus and 10 novel species, 7 novel species belonging to the order and 3 to the genus , based on multilocus phylogenetic analyses combined with morphological characteristics. Our study significantly updates the taxonomy of and and enhances our understanding of this group of the keratin-degrading fungal community. The findings also encourage future studies on the artificially constructed keratin-degrading microbial consortia.

摘要

在中国开展的土壤嗜角质真菌群成员调查中,鉴定出一个新的单种属 ,以及 10 个新种,其中 2 种与 有关,1 种与新属有关,4 种与 有关,3 种与 有关。这些新分类群基于形态和多基因座系统发育分析,形成了与其他物种不同的独立谱系。为每个分类群提供了描述、插图和注释。这些来自中国的土壤嗜角质真菌的新分类群增加了已知真菌的数量,现在显然有许多新的分类群有待描述。嗜角质真菌是一组能够降解和利用富含角蛋白的物质的真菌。也正是由于这种能力,许多分类群可以在动物或人类中引起感染,但仍未得到充分研究。在这项研究中,我们根据多基因座系统发育分析结合形态特征,报道了一个新属和 10 个新种,其中 7 个新种属于目 ,3 个新种属于属 。我们的研究极大地更新了 和 的分类学,并增强了我们对这组角蛋白降解真菌群落的理解。这些发现还鼓励未来对人工构建的角蛋白降解微生物共生体进行研究。
