Saccharata Denman & Crous, in Crous et al., CBS Diversity Ser. (Utrecht) 2: 104 (2004).
Index Fungorum number: IF 28918; Facesoffungi number: FoF 02297, 19 morphological species (Species Fungorum 2022), 15 species with molecular data.
Saprobic on host. Sexual morph: Ascomata pseudothecial, unilocular, solitary or in group, with multilayered dark brown walls, infrequently embedded in stromatic tissue, with upper ascomatal layer darkened and thickened. Asci bitunicate, fissitunicate, 8-spored, with a thick endotunica, stalked or sessile, clavate, with a well-developed apical chamber. Pseudoparaphyses intermixed with asci, hyaline, septate, hyphae like, branched or not. Ascospores hyaline to pigmented, granular, septate or not, ellipsoid to ovoid, without mucoid appendages or sheath. Asexual morph: Conidiomata unilocular pycnidial, infrequently embedded in stromatic tissue with thickened, darkened upper layer. Conidiophores sparingly branched, hyaline, subcylindrical, or reduced to conidiogenous cells. Conidiogenous cells hyaline, smooth, phialidic, proliferating via periclinal thickening or per current proliferation, with or without collarettes. Conidia hyaline, thin-walled, granular, fusoid, aseptate. Synasexual morph: formed in separate conidiomata, or in same conidiomata with asexual morph. Synasexual conidia pigmented, thick-walled, finely verruculose, ellipsoid or oval, aseptate. Spermatogonia similar to conidiomata in anatomy. Spermatogenous cells ampulliform to lageniform or subcylindrical, hyaline smooth, phialidic. Spermatia developing in conidiomata or spermatogonia, hyaline, smooth, granular, subcylindrical or dumbbell-shaped, with rounded ends (adapted from Slippers et al. 2013).
Type species: Saccharata proteae (Wakef.) Denman & Crous
Notes: Saccharata is unique in having asexual characters, which includes hyaline, fusicoccum-like and pigmented diplodia-like conidia. Saccharata differs from Diplodia and Diplodia-like genera in that the conidia are normally nearly half the size of other Diplodia conidia. Phylogenetically, Saccharata is a well-supported genus in Saccharataceae. Molecular markers available for Saccharata are ITS, LSU and TEF-1.
