Classification: Incertae sedis, Sordariales, Sordariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi
Coprophilous. Sexual morph: Ascomata perithecial, solitary, superficial to semi-immersed, pyriform to subglobose, brown to black, ostiolate, with black necks, surrounded by setae. Peridium membranaceous, outer layer composed of brown cells of textura angularis; inner layer composed of hyaline cells of textura prismatica. Asci 8-spored, unitunicate, subglobose to clavate, pedicellate, apex rounded or truncate, with J- apical ring, evanescent. Ascospores bi-seriate, ellipsoidal to subglobose, brown to dark brown, aseptate, with plate-like wrinkled wall, germ pore at one or both end(s), guttulate. Asexual morph: Undetermined (adapted from Jeng and Krug 1976).
Notes: Jeng and Krug (1976) established Emblemospora, which includes two species, E. ditrema and E. monotreme (type), in Sordariaceae. Species are similar to Diplogelasinospora, Jugulospora and Neurospora in having pyriform ascomata and clavate asci with one-celled ascospores with ornamentation (Jeng and Krug 1976). Molecular data is unavailable for this genus.
Type species: Emblemospora monotrema Jeng & J.C. Krug, Can. J. Bot. 54(16): 1972 (1976).
Other accepted species: Species Fungorum – search Emblemospora.
