Basionym: Coprolepa equorum Fuckel, Jb. nassau. Ver. Naturk. 23–24: 240 (1870) [1869–70]
= Hypocopra equorum (Fuckel) G. Winter, Rabenh. Krypt.-Fl., Edn 2 (Leipzig) 1.2: 178 (1885)
Saprobic on dung. Sexual morph: Stromata 100–300 µm diam., immersed to erumpent, dome-shaped, dark brown-black, loosely clustered, slightly roughened, clypeate, presence of brown hyphal mat in which ascomata are embedded, tissue around ascomata white-yellow, delicate. Ostioles papillate, shiny black, and surrounded by white hyphae. Ascomata 150–250 µm diam., globose, immersed in stromal tissue, with a short neck, sometimes reaching the surface. Peridium >30 µm, composed of outermost carbonaceous cell layers, thick-walled, several cell layers. Asci 200–250 × 9–15 µm, 8-spored, unitunicate, cylindrical, short-pedicellate, J+ apical ring bluing in Melzer’s reagent, inverted hat-shaped, with 2–3 distinct rings, 4–6 × 3–5 µm. Ascospores 15–24 × 7–12 lm, uniseriate, unicellular, equilateral ellipsoidal, with narrow to broad ends, dark brown, germ slit straight, less than spore length. Asexual morph: Undetermined.
Material examined – CZECH REPUBLIC, Moravia: Ratschitz, August 1886, Niessl (F10545, isolectotype).
Notes – The species was invalidly published by Krug and Lundqvist (2000), which was later validated by Doveri (2008). We have illustrated the isolectotype of the species housed at S.
