Saprobic on wood. Sexual morph: Ascomata solitary or scattered, immersed to erumpent, black, turbinate, the apex collapsing when dry, tuberculate, sitting in a subiculum, lacking ostioles, with a central, conical Quellkörper. Peridium composed of brown to hyaline cells of textura angularis to textura prismatica, Munk pores present. Paraphyses absent. Asci polysporous, unitunicate, clavate, with long pedicel, apex rounded, without apical ring, evanescent. Ascospores overlapping, hyaline, allantoid to cylindrical, slightly curved, aseptate, smooth-walled, guttulate. Asexual morph: Undetermined (adapted from Mugambi & Huhndorf 2010).
Notes – We establish Neocryptosphaerella based on Cryptosphaerella celata (type) and C. globosa. Mugambi & Huhndorf (2010) introduced six ‘Cryptosphaerella’ species having ascomata lacking ostioles and a Quellkörper. The characteristics of the type of Cryptosphaerella are ostiolate ascomata lacking a Quellkörper (Saccardo 1882a) (see notes for Cryptosphaerella). Therefore, Cryptosphaerella should not belong to Scortechiniaceae and these six species do not belong to Cryptosphaerella based on morphology. Phylogenetically, C. celata and C. globosa form an independent clade and the remaining four species form another clade in Scortechiniaceae (Mugambi & Huhndorf 2010). The phylogenetic position of the type of Cryptosphaerella is undetermined. We therefore introduce Neocryptosphaerella for C. celata and C. globosa. This genus is sister to Biciliospora, Coronophorella, Pseudocryptosphaerella, Scortechiniella and Scortechiniellopsis in Scortechiniaceae, and has ascomata lacking ostioles, Quellkörper and polysporous asci with allantoid to cylindrical ascospores (Mugambi & Huhndorf 2010, this study, 0.98BY).
