Classification: Nitschkiaceae, Coronophorales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi

Saprobic on wood. Sexual morph: Subiculum composed of numerous, brown to dark brown, branched, septate hyphae, with dichotomously branched, rounded ends. Ascomata densely gregarious, superficial, sitting in a subiculum, coriaceous, black, globose to subglobose, the apex collapsing when dry, tuberculate, lacking ostioles, with a central, conical Quellkörper. Peridium composed of membranaceous, brown to hyaline cells of textura angularis to textura prismatica, Munk pores present. Paraphyses absent. Asci polysporous, arising from a hyaline placenta-like tissue, radially extending into the locule around the Quellkörper from the base, unitunicate, clavate, pedicellate, apex rounded, without apical ring, evanescent. Ascospores overlapping, hyaline, cylindrical to oblong, slightly curved, aseptate, smooth-walled, guttulate. Asexual morph: Undetermined (adapted from Saccardo 1882b).

Notes – The monotypic Neofracchiaea was introduced by Teng (1938) based on Cucurbitaria callista, which was considered to be a member of Cryptosphaerella, Fracchiaea or Nitschkia based on similar charcteristics (Saccardo 1882a, Fitzpatrick 1924, Nannfeldt & Santesson 1975). However, Neofracchiaea nested in Scortechiniaceae as an independent clade based on phylogenetic results (Huhndorf et al. 2004b, Mugambi & Huhndorf 2010). In this study, Neofracchiaea is sister to Scortechinia and Tympanopsis

Type species: Neofracchiaea callista (Berk. & M.A. Curtis) Teng, Sinensia, Shanghai 9: 255 (1938).

Other accepted species: Species Fungorum – search Neofracchiaea.
