Stromata hemispherical to effused-pulvinate, plane or with inconspicuous to conspicuous perithecial mounds, 1.5-3 mm thick; surface fulvous (43), sienna (8), or rust (39); orange red granules immediately beneath surface and between perithecia, with KOH-extractable pigments orange (7) or scarlet (5); the tissue below the perithecial layer black, 0.5-1.5 mm thick.

Perithecia long tubular, 0.3-0.6 mm diam x 0.8-2.5 (-3) mm high.

Ostioles lower than the stromatal surface.

Asci 240-320 mm total length x 8-11 mm broad, the spore-bearing parts 80-110 mm long, the stipes 157-225 mm long, with apical ring bluing in Melzer's iodine reagent, discoid, 1-2 (-2.5) mm high x 3-4 mm broad.

Ascospores brown to dark brown, unicellular, ellipsoid-inequilateral, with narrowly rounded ends, 13.5-18 (-19) x 7-8 (-8.5) mm, with straight germ slit spore-length; perispore dehiscent in 10% KOH, smooth; epispore smooth.
