Classification: Niessliaceae, Hypocreales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi
Saprobic on wood. Sexual morph: Ascomata perithecial, solitary or scattered, semi-immersed to superficial, pyriform, globose to subglobose, pale brown to brown, membranaceous, ostioles surrounded by cylindrical, brown to black, septate setae, periphysate. Peridium membranaceous, brown cells of textura epidermoidea on surface view; inner layer composed of brown to hyaline cells of textura angularis to textura prismatica. Paraphyses filiform, septate, evanescent. Asci 8-spored, unitunicate, clavate, pedicellate, apex blunt, evanescent. Ascospores uni- or bi-seriate or overlapping, hyaline when young, becoming olivaceous brown, ellipsoidal to fusiform, 1-septate, slightly constricted at the septum, tuberculate, guttulate. Asexual morph: Undetermined (adapted from Tsui et al. 2001).
Notes – The monotypic Paraniesslia was introduced by Tsui et al. (2001) for P. tuberculata. It is similar to Niesslia with setose ascomata and clavate asci, differing from it in the possessing of tuberculate, ellipsoidal ascospores (Tsui et al. 2001). There is no molecular data available for Paraniesslia.
Type species: Paraniesslia tuberculata C.K.M. Tsui, K.D. Hyde & Hodgkiss, Mycologia 93(5): 1002 (2001).
Other accepted species: Species Fungorum – search Paraniesslia.
