Type species – Pseudorhypophila mangenotii (Arx & Hennebert) Y. Marín & Stchigel.

Etymology –  Based on the phylogenetic relation to Rhypophila.

Sexual morph Ascomata non-ostiolate or ostiolate, superficial or immersed, black, globose to subglobose, or ovate to pyriform, almost glabrous or covered by short or long, flexuous hairs; neck short, cylindrical to conical, covered with small black papillae. Asci clavate to cylindrical, stipitate, 4–8-spored, with a small apical ring, sometimes indistinct. Periphyses present or absent. Paraphyses present or absent, septate, hyaline. Ascospores biseriate, two-celled; upper cell narrowly conical, acuminate towards apex and rounded at base, or ovoid to limoniform with somewhat truncate base, olivaceous brown to dark brown, with an apical or subapical germ pore, sometimes with a distinct apical appendage; lower cell remaining hyaline, or sometimes becoming pale olivaceous brown or pale brown, occasionally dark brown, cylindrical and straight or curved, or hemispherical, or at first broadly obconical and then becoming flattened at apex; gelatinous sheats sometimes present, hyaline, thin. Asexual morph Conidia holoblastic, sessile, borne singly along the vegetative hyphae, hyaline, spherical to subspherical, or ovate to elongate, smooth-walled.

Notes – Pseudorhypophila is related to Gilmaniella and Rhypophila. The former genus produces the humicola-like asexual morph characterized by the production of dark brown, spherical conidia with marked apical germ pores and borne singly or in clusters of up to four [34], while the new genus Pseudorhypophila produces a chrysosporium-like asexual morph, and the asexual morph is absent in Rhypophila [4]. Rhypophila differs from Pseudorhypophila by the production of ascomata with elongate, tuberculate projections in the neck, while these are mostly non-ostiolate ascomata in the new genus. Moreover, Rhypophila is characterized by having mostly more than eight-spored asci and ascospores with lower cell as long as, or longer, than the upper cell.
