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.
摘要：
四种新的角质形成植物（子囊，Pezizomycotina,Onygenales),K.gollerae，K.lemmensii,K.Straussii,还有K.Wagneri,从源自欧洲的土壤样本中分离出来(奥地利，意大利,和斯洛伐克)进行了描述和说明。新的分类单元得到了内部转录间隔区（ITS）区域的系统发育分析的很好支持，ITS和核大亚基（LSU）rDNA的组合数据分析，和他们的表型。基于ITS的系统发育，在角质形成进化枝里面，K.lemmensii与K.durum聚集在一起，K.Hubeiense,K、潜水器，和K.siglerae,而K.gollerae,K.straussii和K.wagneri在一个单独的终端集群中解析。仅根据表型特征，所有四个新物种都可以很好地与该属中的其他物种区分开。针对金孢子菌物种提出了十种新组合，这些组合在单系角化菌进化枝中得以解决。本文提供了识别物种的新密钥。
