Classification: Niessliaceae, Hypocreales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi
Saprobic on wood or leaves. Sexual morph: Ascomata perithecial, scattered or gregarious, semi-immersed to superficial, globose to subglobose, black, membranaceous, surrounded by cylindrical, hyaline setae with swollen apex, ostiolate, periphysate. Peridium membranaceous, composed of brown to hyaline cells of textura angularis to textura prismatica. Paraphyses filiform, septate, unbranched. Asci 6–8-spored, unitunicate, clavate, pedicellate, apical ring distinct. Ascospores uni- or bi-seriate, hyaline to subhyaline, cylindrical to fusiform, slightly curved, 1-septate, slightly constricted at the septum, tuberculate, guttulate, with a mucilaginous sheath. Asexual morph: Undetermined (adapted from Tibpromma et al. 2018).
Notes – The monotypic Pseudohyaloseta was established by Tibpromma et al. (2018) for P. pandanicola. This genus is closely related to Niesslia nolinae based on phylogenetic result. However, the latter has different ellipsoidal ascospores without a sheath (Tibpromma et al. 2018). In this study, Pseudohyaloseta is sister to the clade of N. antarctica, N. gamsii (asexual morph) and N. nolinae (100%ML/1.00BY), which have ellipsoidal ascospores without a sheath.
Type species: Pseudohyaloseta pandanicola Tibpromma & K.D. Hyde, in Tibpromma et al., Fungal Diversity 93: 113 (2018).
Other accepted species: Species Fungorum – search Pseudohyaloseta.
