TELEOMORPH

Stromata effused-pulvinate, with inconspicuous to conspicuous perithecial mounds, 0.8-1 mm thick; surface dark vinaceous (82) or brown vinaceous (84); blackish granules immediately beneath surface and between perithecia, with KOH-extractable pigments dark violet (33), livid violet (79), or dark slate blue (11); the tissue below the perithecial layer black, ca. 0.5 mm thick.

Perithecia tubular, 0.2-0.3 mm diam x 0.4-0.6 mm high.

Ostioles slightly higher than or at the same level as the stromatal surface, with umbilicate central perforation.

Asci 85-115 mm total length x 4-5 mm broad, the spore-bearing parts 37-52 mm long, the stipes 43-63 mm long, with apical ring bluing in Melzer's iodine reagent, discoid, 0.5-0.8 mm high x 1.5-2 mm broad.

Ascospores light brown to brown, unicellular, ellipsoid-inequilateral, with narrowly rounded ends, 6-7.5 x 3-3.5 mm, with straight germ slit spore-length; perispore dehiscent in 10% KOH, smooth; epispore smooth.
