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.
A new species, Saksenaea dorisiae (Mucoromycotina, Mucorales), isolated from a water sample originating from a private well in Manastirica, Petrovac, in the Republic of Serbia (Europe), is described and illustrated. The new taxon is well supported by multilocus phylogenetic analysis that included the internal transcribed spacer (ITS) region, domains D1 and D2 of the 28S rRNA gene (LSU), and translation elongation factor-1α gene (tef-1α), and it is resolved in a clade with S. oblongispora and S. trapezispora. This fungus is characterized by its moderately slow growth at 15 and 37°C, sparse rhizoids, conical-shaped sporangia, and short-cylindrical sporangiospores. Saksenaea dorisiae is a member of the opportunistic pathogenic genus often involved in severe human and animal mucormycoses encountered in tropical and subtropical regions. Despite its sensitivity to several conventional antifungals (terbinafine and ciclopirox), the fungus can potentially evoke clinically challenging infections. This is the first novel taxon of the genus Saksenaea described from the moderately continental climate area of Europe.

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.

A new species Saksenaea dorisiae (Mucoromycotina, Mucorales), recently isolated 18 from a water sample originating from a private well in a rural area of Serbia (Europe), is 19 described and illustrated. The new taxon is well supported by phylogenetic analysis of the 20 internal transcribed spacer region (ITS), domains D1 and D2 of the 28S rRNA gene (LSU), and 21 translation elongation factor-1α gene (TEF-1α), and it is resolved in a clade with S. 22 oblongispora and S. trapezispora. This fungus is characteristic by its moderately slow growth 23 at 15 and 37°C, sparse rhizoids, conical-shaped sporangia and short-cylindrical 24 sporangiospores. S. dorisiae is a member of the opportunistic pathogenic genus often 25 involved in severe human and animal mucormycoses encountered in tropical and subtropical 26 regions. Despite its sensitivity to several conventional antifungals (terbinafine and 27 ciclopirox), the fungus is potentially causing clinically challenging infections. This is the first 28 novel taxon of the genus Saksenaea described from the moderately continental climate area 29 of Europe.30
