Description: | Ascomata scattered, erumpent through the host tissue to becoming superficial, 600-1000 μm wide, 400-550 μm high, flattened at base, apex non-papillate, with ruptured reflexed teeth-like host remnants around the base. Peridium at sides carbonaceous, composed of opaque and melanized cells, poor developed at base, cells at rim appearing as palisade-like rows. Asci cylindrical, 170-240 × 11-13 μm, sessile to short stalked, (4-7)8-spored. Pseudoparaphyses embedded in gelatinous matrix, frequently branched and anastomosing, 1-1.5 μm wide. Ascospores ellipsoid to fusiform, 40-56 × 5.5-7 μm, acute, pale brown, smooth, constricted at the median or slightly supra-median septum, surrounding by a sheath, sheath truncate or sometimes concave at ends, ascospores uniseriate to partially overlapping biseriate in ascus. | |||

Note: | This species is widely distributed at low altitude regions in Taiwan. The characteristic sheath of ascospores with truncate ends serves as an excellent criterion to recognize this species. | |||
