Ascospores bi-seriate, hyaline, fusiform, straight or slightly curved, 0–1-septate, faintly striate, guttulate. Asexual morph: Undetermined (copied from Huang et al. 2021).


Type species: Pseudorhynchia polyrrhyncha (Penz. & Sacc.) Höhn., Sber. Akad. Wiss. Wien, Math.-naturw. Kl., Abt. 1 118: 1206 (1909)




Notes: Pseudorhynchia was established by von Höhnel (1909a) based on Ceratostomella polyrrhyncha. The second species, P. mauritiana, was collected from leaves of Cordemoya integrifolia in Mauritius. They are characterized by ascomata with ostioles surrounded by long setae and fusiform ascospores (Penzig & Saccardo 1897, Dulymamode et al. 2001). Lumbsch & Huhndorf (2007) placed this genus in Niessliaceae, but no sequence data is available (copied from Huang et al. 2021).
