Hypoxylon ticinense L. E. Petrini apud L. E. Petrini & Müller, Mycol. Helv. 1: 534. 1986.

Stromata effused-pulvinate, plane or with inconspicuous perithecial mounds, 2-5 cm long x 0.8-4 cm broad x 1-1.5 mm thick; surface rust (39), sepia (63), bay (6), or dark brick (60); orange red granules immediately beneath surface and between perithecia, with KOH-extractable pigments orange (7); the tissue below the perithecial layer black, 0.6-1 mm thick.

Perithecia obovoid to tubular, 0.1-0.2 mm diam x 0.2-0.4 mm high.

Ostioles lower than the stromatal surface.

Asci 75-95 (-117) mm total length x 3.5-5 mm broad, the spore-bearing parts 40-45 mm long, the stipes 35-63 (-72) mm, with apical ring bluing in Melzer's iodine reagent, discoid, 0.2 mm high x 1 mm broad.

Ascospores light brown to brown, unicellular, ellipsoid-inequilateral, with narrowly rounded ends, 5-7 x 2.5-3.5 mm, with straight germ slit spore-length; perispore dehiscent in 10% KOH, smooth; epispore smooth.
