Peridium 25–35μm thick at the upper part, two-layered, forming textura angularis; outer layer 10–15μm comprising polygonal, brown to dark-brown thick-walled cells; inner layer 12–15μm wide, comprising hyaline thin-walled flattened cells; peridium at the lower part of the ascomata is one-layered, hyaline to light brown comprising of 10–15μm diam. polygonal flattened cells. Hamathecium comprising numerous, 1.5–3μm wide, septate, trabeculate pseudoparaphses, branched, within a gelatinous matrix, anastomosing above the asci and emerging through the ostiolar canal. Asci 115–162×23–34μm (x =37.2×29.3μm, n=25), 8-spored, bitunicate, fissitunicate, clavate, short pedicellate, apically rounded, with an ocular chamber. Ascospores 30–39× 9–13μm (x = 34.9 × 11.4μm, n=60), overlapping biseriate, hyaline, 1–septate, the septum is sub-median, upper cell longer and wider, slightly curved, guttulate; senescent ascospores are larger 38 43×11–14μm (x = 40.5 × 12.5 μm, n = 15), light brown, flattened, striate, verrculose, 2–3-septate.
