Teratosphaericola Quaedvl. & Crous, in Quaedvlieg et al., Persoonia 33: 32 (2014).
Index Fungorum number: IF 807841; Facesoffungi number: FoF 07040, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.
Foliicolous, plant pathogenic. Sexual morph: Ascomata pseudothecial, solitary, black, immersed becoming erumpent, globose; ostiole apical, central; wall of 2–3 cell layers of medium brown textura angularis. Asci aparaphysate, fasciculate, bitunicate, subsessile, narrowly ellipsoid to subcylindrical, slightly incurved, 8-spored. Ascospores tri- to multiseriate, overlapping, hyaline to pale brown, guttulate, thin-walled, straight to slightly curved, smooth to finely roughened, fusoid-ellipsoidal with subobtuse ends, medianlyuniseptate. Spermatogonia similar to the ascomata in morphology. Spermatia hyaline, smooth, rod-shaped with rounded ends. Asexual morph: Unknown (adapted from Quaedvlieg and Crous 2014).
Type species: Teratosphaericola pseudoafricana (Crous & T.A. Cout.) Quaedvl. & Crous
Notes: Teratosphaericola is characterised by pseudothecial, black, immersed becoming erumpent ascomata, fasciculate, bitunicate, narrowly ellipsoid to subcylindrical asci and hyaline to pale brown ascospores. Teratosphaericola morphologically resembles Teratosphaeria but can be differentiated based on DNA sequence data. The ideal molecular marker that can distinguish Teratosphaericola from similar genera are ITS and LSU. Teratosphaericola is a distinct and well-defined genus in Teratosphaeriaceae. Molecular markers available for Teratosphaericola are ITS, LSU, Actin, BTUB, Calmodulin, RPB2 and TEF-1.
