Classification: Niessliaceae, Hypocreales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi
Saprobic on leaves. Sexual morph: Ascomata perithecial, solitary, immersed to erumpent, pyriform to subglobose, brown or black, membranaceous, with short setae around the ostioles, periphysate, collapsing when dry. Setae cylindrical, expanded near the apex, aseptate, branched or unbranched, dark brown. Peridium composed of membranaceous, brown to hyaline cells of textura epidermoidea to textura angularis to textura prismatica. Paraphyses cylindrical, unbranched, septate, constricted at the septum. Asci 8-spored, unitunicate, clavate, pedicellate, apex blunt, apical ring indistinct, evanescent. Ascospores bi-seriate or overlapping, hyaline, fusiform, with rounded ends, straight or slightly curved, 1-septate, smooth-walled, guttulate. Asexual morph: Undetermined (adapted from Scheuer 1993).
Notes – The monotypic Cryptoniesslia was established by Scheuer (1993) for C. seutlosa, which has similarly immersed ascomata with special setae to Niesslia and Trichosphaerella.
Type species: Cryptoniesslia setulosa Scheuer, Mycol. Res. 97(5): 543 (1993).
Other accepted species: Species Fungorum – search Cryptoniesslia.
