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

Parasitic on various moniliaceous hyphomycetes, or isolated from soil, or lichenicolous. Sexual morph: Ascomata perithecial or without an external opening, solitary, superficial to immersed, globose to subglobose, sometimes with long necks, pale brown to brown, membranaceous, glabrous or setose or hairy, with or lacking ostioles. Necks absent or cylindrical, composed of fasciculate, cylindrical, septate hyphae, straight or slightly curved. Peridium membranaceous, composed of pale brown to brown cells of textura angularis. Asci 8-spored, unitunicate, clavate, evanescent. Ascospores irregular or bi-seriate, hyaline becoming brown or olivaceous brown, broadly fusiform to cylindrical to doliiform, truncate at both ends, aseptate, smooth-walled or with reticulate ribs on surface, with a large depressed germ pore at each end, mostly with guttules. Asexual morph: Hyphomycetous. Mycelium consisting of hyaline to yellowish brown, branched, septate, smooth-walled hyphae. Chlamydospores terminal to intercalary, globose to ovoid, hyaline to brown (adapted from Cannon & Hawksworth 1982, Horie et al. 1986, García et al. 2002, Etayo & Sancho 2008).

Notes – Syspastospora was established as a genus similar to Melanospora, and its generic type, S. parasitica, has cylindrical to doliiform ascospores with large terminal depressed germ pores at each end, whereas Melanospora has ellipsoidal to citriform ascospores (Cannon & Hawksworth 1982). The strain of S. parasitica nested in Hypocreales (Zhang & Blackwell 2002). This genus was accepted as a member of Ceratostomataceae based on multi-gene analyses (Marin-Felix et al. 2018, Hyde et al. 2020e, Wijayawardene et al. 2020). In this study, Syspastospora is sister to Gonatobotrys and Vittatispora in Ceratostomataceae (54%ML/0.99BY).
