New Keratinophyton species (Onygenaceae) from Europe
Four new Keratinophyton species (Ascomycota: Pezizomycotina, Onygenales), isolated from soil samples originating from Europe (Austria, Italy and Slovakia) are described, illustrated and presented here. The new taxa are well supported by phylogenetic analysis of the internal transcribed spacer region (ITS) region, the nuclear large subunit (LSU) rDNA, and their phenotype. Within the Keratinophyton clade, Keratinophyton sp. 1 is clustered with K. durum, K. hubeiense, K. submersum and K. siglerae, while Keratinophyton sp. 2, Keratinophyton sp. 3 and Keratinophyton sp. 4 are resolved in a separate terminal cluster. All four new species can be well distinguished from the other asexual taxa in the genus Keratinophyton based on phenotypical characteristics alone. Ten new combinations are proposed for all other Chrysosporium asexual morphs which are resolved in the monophyletic Keratinophyton clade.
