Abstract: During the course of a project investigating culturable Ascomycota diversity from freshwater sediments in Spain, we isolated 63 strains of cycloheximide-resistant fungi belonging to the order Onygenales. These well-known ascomycetes, able to infect both humans and animals, are commonly found in terrestrial habitats, colonizing keratin-rich soils or dung. Little is known about their diversity in aquatic environments. Combining morphological features and sequence analyses of the ITS and LSU regions of the nrDNA, we identified 14 species distributed in the genera Aphanoascus, Arachniotus, Arthroderma, Arthropsis, Emmonsiellopsis, Gymnoascoideus, Leucothecium, Malbranchea, and Myriodontium. Furthermore, three novel species for the genus Malbranchea are proposed as M. echinulata sp. nov., M. irregularis sp. nov., and M. sinuata sp. nov. The new genera Albidomyces and Neoarthropsis are introduced based on Arachniotus albicans and Arthropsis hispanica, respectively. Neoarthropsis sexualis sp. nov. is characterized and differentiated morphologically from its counterpart by the production of a sexual morph. The novel family Neoarthropsidaceae is proposed for the genera Albidomyes, Apinisia, Arachnotheca, Myriodontium, and Neoarthropsis, based on their phylogenetic relationships and phenotypic and ecological traits. Pseudoamaurascopsis gen. nov. is introduced to accommodate P. spiralis sp. nov., a fungus with unclear taxonomy related to Amaurascopsis and Polytolypa. We traced the ecology and global distribution of the novel fungi through ITS environmental sequences deposited in the GlobalFungi database. Studying the fungal diversity from freshwater sediments not only contributes to filling gaps in the relationships and taxonomy of the Ascomycota but also gives us insights into the fungal community that might represent a putative risk to the health of animals and humans inhabiting or transient in aquatic environments.
