Perithecia caespitosa in stromate erumpenti ad 1 cm. diam., globosa vel ovata 0 - 3-0 - 4mm. diam., tubereulata, aurantiaca vel testacea ; ostiolo papillato, pariete perithecii 120,u crasso, cellulis 10-15 x 12-221 µm parietibus densatis et tinctis. Asci parietibus tenuibus, clavati vel elliptiei 140-200 x 18-241cc, 4-8 sporis uniseriatis. Sporae ovatae vel obovatae, uniseptatae 22-38 x 10-16 µm striatae, pallide luteae.

The perithecia are similar to N. balsanae and are arranged on a large pulvinate stroma but the spores are much larger and are biseriately arranged at the apex of the clavate asci.

Perithecia gregarious on an erumptent, prosenchymatous stroma, up to 1 cm diameter, perithecia globose or oval, 0.2-0.3 mm diameter, tuberculate, scarlet or coral coloured, farinaceous with crystals, perithecial wall pseudoparenchymatous, 50 µ thick, cells up to 12 µ diam. walls pigmented and thickened. Asci cylindrical, rarely clavate, truncated, 90-120 x 10-12 µ, 6-8 spored, uniseriate, sometimes biseriate at apex; pseudoparaphyses evanescent. Spores one septate, elliptical or pyriform, ends rounded, 16-24 x 6-10 µ, hyaline or lightly pigmented, striate.

Asci cylindrici raro clavati, truncati 90-120 x 10-12 µ, 6-8 sporis, uniseratis, pseudoparaphysibus evanescentibus.
