Fungal strain PSN 637 was isolated from dung of Sylvilagus floridanus collected in Lambton County, Ontario, Canada. It belongs to Sordariales. Based on ITS sequencing, this strain is most closely related to Rhypophila pleiospora inside Naviculisporaceae. The Rhypophila genus is typified by Rhypophila myriospora (1). It is characterized by the production of ostiolate ascomata with a neck bearing elongated tuberculated projections at the base, asci normally containing more than eight ascospores, and ascospores with a lower cell as long as, or longer than, the upper cell (1). Species from this genus are mainly known as coprophilous (2,3,4,5).
