Classification: Niessliaceae, Hypocreales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi

Saprobic on bamboo. Sexual morph: Ascomata perithecial, solitary to scattered, superficial, subglobose, usually collapsing as cupuliform, yellow, membranaceous to coriaceous, surrounded by erect, septate, unbranched, tapering setae with rounded end, ostioles inconspicuous, periphysate. Peridium composed of membranaceous, yellow to hyaline cells of textura angularis to textura prismatica. Paraphyses absent. Asci 8-spored, unitunicate, cylindrical to clavate, pedicellate, apex blunt, apical ring distinct, evanescent. Ascospores bi-seriate or overlapping, hyaline, fusiform, straight or slightly curved, 1–3-septate, smooth-walled, guttulate. Asexual morph: Undetermined (adapted from Starbäck 1899).

Notes – The monotypic Malmeomyces was initially placed in Hypocreaceae (Starbäck 1899), and subsequently accepted at Niessliaceae based on ascomata with erect setae (Lumbsch & Huhndorf 2010, Maharachchikumbura et al. 2016, Hyde et al. 2020e, Wijayawardene et al. 2020). 

Type species: Malmeomyces pulchellus Starbäck [as ‘pulchella’], Bih. K. svenska VetenskAkad. Handl., Afd. 3 25(no. 1): 32 (1899).

Other accepted species: Species Fungorum – search Malmeomyces
