　Description： Mycelium subepidermal, extensively connecting adjacent ascomata, forming stromatic tissue, which is particularly prominent around ascomata. Ascomata scattered, immersed at first, at maturity erumpent through the host tissue with ruptured host remnants surrounding the ascomata and appearing star-like in surface view, conical, 400?700 μm wide, 300?500μm high, apex non-papillate, flattened at base. Peridium at sides carbonaceous, 25?35 μm thick, composed of melanized, opaque cells except at the inner cell layers of lateral rim where the cells are hyaline and elongated in palisade-like rows; peridium at base much reduced, composed of cells interwoven with host tissue. Asci cylindrical, 130?160 × 14?18 μm, short-stalked, 8-spored. Pseudoparaphyses embedded in gelatinous matrix, frequently branched and anastomosing, 1.5?2.5 μm wide. Ascospores irregularly biseriate in ascus, ellipsoid to fusiform, 24?34 × 6?8 μm, smooth, pale brown, with a conspicuously constricted, submedian septum, surrounded by a sheath which expands around the lower cell and is drawn out at the posterior end to form a tongue-like appendage, up to 20 μm long.

　Note： In some collections, most ascospores examined are hyaline, and prior to the formation of appendage these hyaline ascospores usually give the appearance of having a median septum. However, the occasional existence of brown ascospores with the characteristic tongue-like appendage reveals the identity of A. linguiformis.
