Saprobic on wood. Sexual morph: Subiculum composed of numerous, brown to dark brown, branched, septate hyphae, with dichotomously branched, rounded ends. Ascomata scattered or gregarious, superficial, sitting in a subiculum, coriaceous, brown to black, globose to subglobose, the apex collapsing when dry, glabrous, lacking ostioles, with a central, conical Quellkörper at apex. Peridium composed of membranaceous, brown to hyaline cells of textura angularis to textura prismatica. 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, ellipsoidal to oval, aseptate, smooth-walled, guttulate, with a filiform appendage at each end. Asexual morph: Undetermined (adapted from von Arx & Müller 1954).
Notes – The monotypic Scortechiniella was introduced for S. similis which has similar morphology to Scortechinia, differing in multi-spored asci and ascospores with appendages (von Arx & Müller 1954). Mugambi & Huhndorf (2010) accepted it as a member of Scortechiniaceae based on its molecular data. In this study, Scortechiniella is sister to Biciliospora (85%ML/1.00BY). However, the latter has fusiform ascospores.
Type species: Scortechiniella similis (Bres.) Arx & E. Müll., Beitr. Kryptfl. Schweiz 11(no. 1): 383 (1954).
Other accepted species: Species Fungorum – search Scortechiniella.
