Hypocreomycetidae, Hypocreales, Niessliaceae, Cryptoniesslia
Index Fungorum number: IF 22420; 1 morphological species.
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 (copied from Huang et al. 2021).
Type species: Cryptoniesslia setulosa Scheuer, Mycol. Res. 97(5): 543 (1993)
Notes: Cryptoniesslia setulosa, the only species of Cryptoniesslia, has ascomata surrounded by short, branched, apical setae, clavate asci and elongate ascospores (Scheuer 1993). The setae and ascospores are similar to Niesslia erysipheoides and should be given generic status in Niessliaceae based on different characters of immersed ascomata and clavate asci (Samuels & Barr 1997) (copied from Hyde et al. 2020).
