 Description: Ascomata scattered, immersed, raising the overlying host tissue, hemispherical, 700-800 μm wide, 300-360 μm high, apex papillate, usually elongated to become a neck, flattened at base. Peridium laterally merging with the host tissue to form a shield-like clypeus, much reduced at base, exhibiting a palisade-like arrangement of cells at the rim margin. Asci clavate, 110-130 x 12-14 μm, long stalked, stalk up to 40 μm long, 8-spored. Pseudoparaphyses embedded in gelatinous matrix, frequently branched and anastomosing, 1-1.5 μm wide. Ascospores fusiform, 40-54 x 5-7 μm, acute or occasionally swollen at ends, brown, striate, 1-septate, septum usually slightly constricted, median or supra-median, broadest on the upper cell near the septum, occasionally becoming 3-septate, overlapping bi-triseriate in upper part of ascus and uniseriate below.
