= Rosellinia truncata Syd. & P. Syd., Philipp. J. Sci. 9: 166 (1914)[non Hypoxylon truncatum (Schwein. : Fr.) J. H. Miller (1961)].

º Hypoxylon truncatulum P. Martin, J. S. African Bot. 33: 327 (1967)[nom. inval. Art. 33.2]; J. S. African Bot. 42: 74 (1976, validation).

Stromata pulvinate to effused-pulvinate, superficial, 0.3-5.5 cm long, 0.3-2.5 cm broad, 1-2.2 mm thick; surface dark brown to blackish brown, plane or with inconspicuous perithecial mounds, with margins covered by dark purplish brown subicular hyphae; carbonaceous tissue immediately beneath surface and between perithecia; tissue beneath the perithecial layer inconspicuous to conspicuous, grayish brown.

Perithecia spherical to obovoid, 0.4-0.6 mm diam x 0.5-0.8 mm high.

Ostioles higher than the stromatal surface, with openings papillate to coarsely papillate, with surrounding area slightly flattened.

Asci 145-165 µm total length x 11-12.5 µm broad, the spore-bearing parts 110-130 µm long, the stipes 30-50 µm long, with apical ring bluing in Melzer's iodine reagent, inverted hat-shaped, 3.5-4.5 µm high x 4-4.5 µm broad.

Ascospores brown to dark brown, unicellular, ellipsoidal-inequilateral, with narrowly rounded ends, 15-21 x (6-) 6.5-8.5 µm, with straight, conspicuous germ slit much less than spore-length on the dorsal side.
