Pseudorhypophila Y. Marin & Stchigel

Pseudorhypophila Y. Marín & Stchigel Notes. The genus Pseudorhypophila was proposed accommodate four Zopfiella species namely, Zopfiella mangenotii, Z. marina, Z. pilifera, and Z. submersa, which form a well-supported monophyletic clade within the family Navicularisporaceae in Harms et al. (2021). At present, four species are recognized in MycoBank (Accession date: March 10, 2025). Species in this genus are characterized in their sexual stage by immersed to erumpent ascomata that are non-ostiolate or ostiolate, and globose to subglobose or ovate to pyriform in shape. Asci are clavate to cylindrical, stipitate, and contain 4–8 spores, with a small apical ring that may sometimes be indistinct. Ascospores are biseriate and two-celled, often enclosed in gelatinous sheaths. They are hyaline and thin-walled. The upper cell is olivaceous brown to dark brown, usually narrowly conical with an acuminate apex and a rounded base; occasionally ovoid to limoniform, bearing an apical or subapical germ pore, and sometimes a distinct apical appendage. The lower cell remains hyaline, though it may occasionally appear pale olivaceous brown, pale brown, or even dark brown. It is straight and cylindrical, but may also be curved, hemispherical, or initially broadly obconical, later becoming flattened at the apex (Guarro et al. 1997; Harms et al. 2021). In the asexual stage Pseudorhypophila species produce holoblastic hyaline conidia that are spherical to subspherical, or ovate to elongate, smooth-walled, sessile, borne singly along the vegetative hyphae (Harms et al. 2021; Liu et al. 2025). Pseudorhypophila has been reported from Egypt, France, Iraq, Japan, South Korea and Taiwan, occurring on substrates such as freshwater, plant debris, soil, and mud (Guarro et al. 1997; Chang et al. 2010; Marin-Felix et al. 2020; Hussien et al. 2023; Liu et al. 2025).
