| Description： |
Ascomata perithecial, immersed, solitary or often aggregated, dark brown, subglobose, 180-275 μm thick is composed of dark brown to brown pseudoparenchymatous cells forming a textura angularis. Clypeus dark brown, 50-75 μm high, 275-500 μm long, intra and subepidermal, composed of brown pseudoparenchymatous cells. Ostiole papillate with a round central pore. Paraphyses numerous, unbranched, guttulate, deliquescent. Asci cylindrical, short-stalked, non-fissitunicate, 8-spored, 75-105 × 8-10 μm, with a stopper-shaped, amyloid apical ring, ca 2.5 × 2.5 μm. Ascospores uniseriate, ellipsoid, more or less acute or rounded at the upper ends, smooth, unequally 1-septate, with a hyaline to brown, large upper cell, 15-22.5-× 7.5-10 μm and a basal hyaline, straight to rostrate, dwarf cell, 2.5-7.5 μm long. Germ slit not seen on the ascospores. | |||

| Note： |
A. appendiculata (Berk. & Broome) Sacc. and A. rubicola (Speg.) Sacc. & Trotter (Francis, 1975) are the only two species with similar type of ascospore morphology. However, the ascospores of the former are significantly larger (28-36 × 8-10 μm) and in the latter they are much narrower (23-30 × 5-6 μm). | |||
