Hypoxylon munkii Whalley, Hammelev, & Taligoola, Trans. Brit. Mycol. Soc. 90: 139. 1988.
Stromata effused-pulvinate, plane or with inconspicuous perithecial mounds, 1-7 cm long x 0.7-2.5 cm broad x 0.7-0.8 mm thick; surface white on young stromata, becoming grayish sepia (106), then brown vinaceous (84) when fully mature; white granules immediately beneath surface and between perithecia, without apparent KOH-extractable pigments; the tissue below the perithecial layer inconspicuous.
Perithecia tubular, 0.1-0.2 mm diam x ca. 0.6 mm high.
Ostioles lower than the stromatal surface.
Asci 89-130 (-150) mm total length x 3.5-5.5 mm broad, the spore-bearing parts 36-43 mm long, the stipes 50-94 (-110) mm long, with apical ring bluing in Melzer's iodine reagent, discoid, 0.7 mm high x 1.5-2 mm broad.
Ascospores dark brown, unicellular, ellipsoid-inequilateral, with narrowly rounded ends, 6-8 x 3-4 mm, with straight germ slit spore-length on flattened side; perispore dehiscent in 10% KOH, smooth; epispore smooth.
