Stromata spherical, depressed-spherical to turbinate, sessile or with short, stout stipe, solitary to infrequently aggregated, smooth or with inconspicuous to conspicuous perithecial mounds, 0.5-5 cm diam x 0.8-4 cm high; surface brown vinaceous (84), chestnut (40), or grayish sepia (106), darkened and dull in age; dull orange brown or dull reddish brown granules immediately beneath surface, with KOH-extractable pigments isabelline (65), hazel (88), honey (64), amber (47), or cinnamon (62); the tissue between perithecia brown, pithy to woody; the tissue below the perithecial layer composed of alternating zones, the darker zones dark brown, pithy to woody, 0.2-0.6 mm thick, the lighter zones brown, pithy to woody, persistent, 0.6-1 mm thick.

Perithecia tubular, 0.3-0.5 mm diam x 0.7-1.5 mm high.

Ostioles slightly papillate.

Asci at least 180 mm total length x 8-12 mm broad, the spore-bearing part ca. 90 mm long, the stipe at least 90 mm long, with apical ring bluing in Melzer's iodine reagent, discoid, 0.5 mm high x 3 mm broad. Asci usually fragmentary.

Ascospores brown to dark brown, unicellular, ellipsoid-inequilateral, with narrowly rounded ends, 12-16 x 5.5-7.5 mm, with straight germ slit spore-length on convex side; perispore dehiscent in 10% KOH, smooth; epispore smooth.
