Hypocopra equorum  

Stromata composed of a reduced clypeus surrounding the neck of individual ascomata beneath a mat to ca 3 mm diam. of dark brown subiculum, sometimes covering more than one ascoma.
Anamorph: not known.
Teleomorph: ascomata perithecial, 700–850 µm diam. and 800–900 µm tall, immersed in the substratum, globose, the neck papillate, 120–180 µm tall, not or hardly protruding beyond the surface of the clypeus. Peridium composed of an outer layer of mid brown thin-walled branched intertwined hyphae 3–5 µm diam., and an inner layer of angular pale yellowish brown cells 6–10 µm diam. Interascal tissue composed of numerous thin-walled paraphyses, 5–6 µm diam. at the base and gradually tapering towards the apex, longer than the asci. Asci 240–280 × 20–23 (–25) µm, ± cylindrical, the apical part not attenuated, rather short-stalked, quite thin-walled, the apex obtuse, with a large complex ± cylindrical apical ring structure to 7 µm diam. and 8·5 µm tall that hardly stains blue in Melzer’s reagent, 8-spored. Ascospores arranged uniseriately, 26·5–30·5 × (12·5-) 13·5–15·5 µm, ellipsoidal, not inaequilateral, aseptate, dark chocolate brown, thick-walled, with a straight gem slit 17–20 µm in length and a pale epispore, sometimes with a minute hyaline secondary cell, surrounded by a broad gelatinous sheath to 4 µm thick in the central part of the spore and rather thicker towards the apices.
