Suberoteratosphaeria Quaedvl. & Crous, in Quaedvlieg et al., Persoonia 33: 31 (2014).
Index Fungorum number: IF 807836; Facesoffungi number: FoF 07038; 3 morphological species (Species Fungorum 2022), 3 species with molecular data.
Foliicolous and caulicolous, plant pathogenic. Sexual morph: Ascomata pseudothecial, solitary or aggregated, black, superficial to subepidermal, globose, glabrous. Ostiole apical, central, papillate, lined with periphyses. Peridium comprised of 3–4 layers of medium brown cells of textura angularis, subhymenium of 3–5 layers of hyaline cells. Asci fasciculate, bitunicate, aparaphysate, subsessile, 8-spored, ellipsoid to obclavate, straight or curved. Ascospores bi- to triseriate or irregularly arranged, oblique, overlapping, straight ellipsoidal, obtuse at each end, hyaline to pale brown, smooth,uniseptate, guttulate, with or without mucoid sheath. Asexual morph: Unknown (adapted from Quaedvlieg et al. 2014).
Type species: Suberoteratosphaeria suberosa (Crous, F.A. Ferreira, Alfenas & M.J. Wingf.) Quaedvl. & Crous
Notes: Suberoteratosphaeria is characterised by hyaline to pale brown ascospores. Suberoteratosphaeria differs from Teratosphaeria in having corky lesions, and ascospores that become brown, verruculose and germinate by two or multiple germ tubes. Suberoteratosphaeria is morphologically and phylogenetically a distinct and well-defined genus in Teratosphaeriaceae. Molecular markers available for Suberoteratosphaeria are ITS, LSU, SSU, Actin, BTUB, RPB2 and TEF-1.
