Anthostomella taiwanensis W. H. Hsieh et al., Mycol. Res. 99: 119-121. 1995.

 Description: Ascomata perithecial, immersed, subepidermal, solitarty, scattered, globose to subglobose, 400-500 μm wide, 312-475 μm high, clypeate, ostiolate. Peridium 20-28 μm thick, composed of two layers: the outer layer of dark brown, thick-walled, pseudoparenchymatous cells forming a textura globosa and an inner layer of hyaline, thin-walled, compressed, elongated cells. The host tissues surrounding the perithecium are invaded by hyphae originating form the outer wall and clypeus, and partly destroyed. Clypeus dark brown, intra and subepidermal of hyphae texture, up to 450 μm long. The peridium and the clypeus are predominently more thickened and darkened. Ostiolar region papillate with a central round pore. Paraphyses numerous, unbranched, guttulate, deliquescent. Asci cylindrical, long stalked, non-fissitunicate, 8-spored, 115-165 × 2.5-5 μm, with a stopper-shaped, amyloid apical ring. Ascopsores uniseriate, ellipsoid, smooth, unequally 1-septate with a brown, large upper cell, 7.5-12.5 × 2.5-5 μm and a subhyaline, basal dwarf cell, ca 2 μm wide, germ slit not seen on the ascospores.

 Note: This species is close to A. unguiculata (Mont.) Sacc. (Francis, 1975) in ascospores size but is easily distinguished from it by its slightly larger and conspicuous ascomata, longer pedicellate asci and by different shaped ascospores.
