Pseudoproboscisporaceae H. Zhang, K.D. Hyde & Maharachch., Fungal Divers. 85: 93 (2017)
Index Fungorum number: IF553760; 5 species.
Saprobic on decaying wood and bamboo submerged in freshwater. Sexual morph: Ascomata scattered or solitary, immersed, with long or short neck, dark brown to black, ostiolate. Neck central or lateral, dark brown, erect or curve upwards. Peridium comprising several layers of compressed cells. Paraphyses hypha-like, septate, tapering. Asci 8-spored, unitunicate, cylindrical, pedicellate, with a relatively large, J-, apical ring. Ascospores uni- to tri-seriate, hyaline, fusiform, aseptate or septate, smooth or rugose, thin-walled, with bipolar filamentous appendages. Appendages initially coiled then unfurling to form long threads on release. Asexual morph: Undetermined (adapted from Zhang et al. 2017a).
Type genus – Pseudoproboscispora Punith.
Notes – Pseudoproboscisporaceae was introduced in a newly established order Atractosporales by Zhang et al. (2017a) based on phylogenetic and morphology and included two genera Diluviicola and Pseudoproboscispora. Cateractispora also clustered in Pseudoproboscisporaceae in the phylogenetic tree (Zhang et al. 2017a), however, it has not been validly published (Ranghoo et al. 1999). Zhang et al. (2017a) observed the photo-plate of C. recepticuli from the PhD thesis of Ranghoo (1998) and thought that Cateractispora was likely to be a synonym of Pseudoproboscispora
