Caryosporella Kohlm., Proc. Indian Acad. Sci., Pl. Sci. 94(2-3): 355 (1985).
Index Fungorum number: IF 903; Facesoffungi number: FoF 00768, 1 morphological species (Species Fungorum 2022), no molecular data available.
Saprobic on host. Sexual morph: Ascocarps gregarious, large, subglobose, superficially seated on a thin black stroma, ostiolate, periphysate, papillate, carbonaceous, black. Peridium thick, three-layered, yellow on the outside, brown in the middle, hyaline near the centrum, the outer two layers forming a textura epidermoidea, the inner one a textura prismatica. Pseudoparaphyses trabeculate, thin, simple between the asci, branched and anastomosing above them, embedded in a gelatinous matrix. Asci 8-spored, cylindrical, pedunculate, bitunicate, thick-walled, with an apical cap-like apparatus, maturing successively on an ascogenous tissue at the bottom of the locule. Ascospores ellipsoidal, uniseptate, dark brown with a light-colored tip, indistinctly verruculose. Asexual morph: Unknown (adapted from Kohlmeyer 1985).
Type species: Caryosporella rhizophorae Kohlm.
Notes: Caryosporella is characterised by gregarious, large, subglobose ascocarps, cylindrical, pedunculate asci and ellipsoidal, one-septate, dark brown ascospores. Kohlmeyer (1985) suggested that Caryosporella fits within the concept of the Melanommatales (Barr 1979b, 1983) and Massariaceae (Barr 1979a). Caryosporella differs from members of Massariaceae in having entirely superficial ascocarps and the medium-sized ascospores (Barr 1979a). Caryosporella resembles Caryospora but differs in having superficial ascocarps, peridium comprising 3 layers of cells and thick-walled ascospores. Molecular data is lacking for Caryosporella. Fresh collections with DNA sequence data are needed to confirm the systematic position of Caryosporella.
