Stromata glomerate to effused-pulvinate, with the tendency to be perithecioid (approaching rosellinioid) but united by very thin stromatal tissue, usually confluent, with very conspicuous perithecial mounds, 0.2-3 cm diam x 0.4-1 mm thick; surface grayish sepia (106), fuscous (103), or brown vinaceous (84); dull orange brown or dark brown granules immediately beneath surface and between perithecia, with KOH-extractable pigments hazel (88), sienna (8), cinnamon (62), fulvous (43), umber (9), or ochreous (44); the tissue below the perithecial layer inconspicuous.

Perithecia spherical, 0.3-0.5 (-0.6) mm diam.

Ostioles slightly higher than the stromatal surface.

Asci 123-170 mm total length x 6-9 mm broad, the spore-bearing parts 70-104 mm long, the stipes 38-81 mm long, with apical ring bluing to lightly bluing in Melzer's iodine reagent, discoid, 0.7-1.5 mm high x 2-3 mm broad.

Ascospores brown to dark brown, unicellular, ellipsoid-inequilateral, with narrowly rounded ends, 9.5-15 (-16) x 4-6.5 (-7) mm, with slightly sigmoid germ slit spore-length; perispore dehiscent in 10% KOH, with inconspicuous coil-like ornamentation; epispore smooth.
