Four new Keratinophyton species (Onygenaceae) from Europe

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 asexual morphs in the genus Keratinophyton based on phenotypical characteristics alone. Ten new combinations are proposed for Chrysosporium asexual morphs which are resolved in the monophyletic Keratinophyton clade.
