Stromata turbinate to depressed-spherical, sessile or with short, stout stipe, solitary to infrequently aggregated, smooth, sometimes with major wrinkles, 0.4-1.8 cm diam x 0.3-1.3 cm high; surface brown vinaceous (84) or grayish sepia (106), blackened and varnished in age; dull reddish brown granules immediately beneath surface, with KOH-extractable pigments livid purple (81), dark livid (80), vinaceous purple (101), or without apparent KOH-extractable pigments; the tissue between perithecia whitish, gray, or brown, pithy to woody; the tissue below the perithecial layer composed of alternating zones, the darker zones dark brown, pithy to woody, 0.1-0.3 mm thick, the lighter zones whitish, gray, or brown, pithy to woody, persistent, 0.3-1 mm thick.
Perithecia obovoid, 0.2-0.5 mm diam x 0.5-0.8 mm high.
Ostioles obsolete or slightly papillate.
Asci 140-155 mm total length x 6-7 mm broad, the spore-bearing part 60-75 mm long, the stipe 60-80 mm long, with apical ring bluing in Melzer's iodine reagent, discoid, 0.5 mm high x 2 mm broad.
Ascospores brown to dark brown, unicellular, ellipsoid, slightly inequilateral to equilateral, with broadly to, less frequently, narrowly rounded ends, 8-11 (-12) x 4-5.5 mm, with straight germ slit spore-length usually on less convex side; perispore indehiscent in 10% KOH; epispore smooth.
