MycoBank number: MB 313497; Index Fungorum number: IF 313497; Facesoffungi number: FoF 10040; Fig. 57
Coprophilous . Sexual morph : Ascomata 450–600 × 230–380 µm (x̄ = 500 × 300 µm, n = 5), perithecial, solitary, superficial to semi-immersed, pyriform to subglobose, brown to black, membranaceous, ostiolate, with black necks (65–100 × 100–120 µm), sur- rounded by setae, with hyaline, septate periphyses. Setae 1.5–3.5 µm wide, numerous, cylindrical, erect, septate, apex rounded, brown and tapering lighter at the apex. Peridium 18–35 µm (x̄ = 27 µm, n = 20) wide, two layers, outer layer composed of brown cells of textura angularis; inner layer composed of hyaline cells of textura prismatica. Asci 160–225 × 25–55 µm (x̄ = 190 × 40 µm, n = 30), 8-spored, unitunicate, subglobose to clavate, pedicellate, apex rounded, with J- apical ring, evanescent. Ascospores 27–35 × 15–25 µm (x̄ = 30 × 20 µm, n = 50), bi-seriate, ellipsoidal to subglobose, brown to dark brown, aseptate, with plate-like wrinkled wall and an apical germ pore, guttulate. Asexual morph: Undetermined.
Material examined: Venezuela, Edo. Scure, NW of Irapa, trail between Manacal and Los Pocitos, on dung of burro, 13 July 1972, K.P. Dumont, R.F. Cain, G.J. Samuels, G. Morillo and J. Farfan (TRTC-175786, holotype).
Known hosts and distribution: On dung of burro in Venezuela (type locality) (Jeng and Krug 1976).
Notes: Emblemospora monotrema is similar to Neurospora species and is characterized by pyriform ascomata and clavate asci with one-celled ornamented ascospores (Jeng and Krug 1976).
