Anthosulcatispora
Anthosulcatispora Phukhams. & K.D. Hyde, in Phukhamsakda et al., Fungal Diversity: 10.1007/s13225-020-00448-4, [117] (2020).
Index Fungorum number: IF 557201; Facesoffungi number: FoF 07340, 2 morphological species (Species Fungorum 2022), 2 species with molecular data.
Saprobic on dead stems of herbaceous plants. Sexual morph: Ascomata semi-immersed, blackish, irregular, scattered, uniloculate, glabrous, ostiolate, apapillate. Ostioles dark, circular and sunken. Peridium two-layered, outer layer irregular, comprising dark brown cells of textura angularis and inner layer irregular comprising light brown cells. Hamathecium composed of numerous, filamentous, branched or simple, septate, cellular pseudoparaphyses, embedded in a hyaline gelatinous matrix. Asci 4- or 8-spored, bitunicate, cylindrical to cylindrical-clavate, short pedicellate, apically rounded, with an ocular chamber. Ascospores 1-seriate, brown to dark brown, oblong to ellipsoidal, with rounded ends, uniseptate, slightly constricted at the septum, smooth walled (Phookamsak et al. 2019). Asexual morph: Conidiomata pycnidial, solitary or gregarious, unilocular, scattered, immersed or erumpent, base fattened, subglobose to compressed, coriaceous, dark brown to reddish brown, with or without ostioles. Pycnidial wall multilayered with cells textura angularis, inner layer bearing conidiogenous cells. Conidiophores reduced to conidiogenous cells. Conidiogenous cells enteroblastic, phialidic, determinate, elongated cylindrical or truncate, smooth-walled, hyaline. Conidia oblong, ends rounded, hyaline, aseptate, guttulate, smoothwalled, with mucilaginous sheath (adapted from Phukhamsakda et al. 2020).
Type species: Anthosulcatispora subglobosa Phukhams. & K.D. Hyde
Notes: Anthosulcatispora is unique from other genera in Sulcatisporaceae in having brown ascospores while sexual morph of Sulcatispora is characterised by hyaline, broadly fusiform ascospores with an entire sheath (Phukhamsakda et al. 2020). The asexual morph of Anthosulcatispora resembles those of Neobambusicola and Pseudobambusicola in having solitary, unilocular pycnidia, phialidic conidiogenesis and hyaline conidia (Phukhamsakda et al. 2020). The asexual morph of Anthosulcatispora differs from Neobambusicola and Pseudobambusicola in having subglobose conidiomata, elongated cylindrical to truncate conidiogenous cells and oblong, aseptate conidia. Anthosulcatispora is a distinct and well-supported lineage in Sulcatisporaceae. Molecular markers available for Anthosulcatispora include ITS, LSU, SSU, RPB2 and TEF-1.
