Index Fungorum number:                                     Faceoffungi number:

Sexual morph: saprobic, ascomata 100-160 µm high, 250-400 µm in diameter, depressed, immersed, ostiolate, papillate, clypeate, coriaceous, light-coloured, single. Papilla 100-200 µm high, 40-75 µm diam, conical, brown, periphysate, projecting above the wood surface, surrounded by an irregular small, brown clypeus that penetrates into the lumina of wood vessels. Peridium 8.5-15 µm thick, composed of 4-6 layers of polygonal cells forming a textura angularis, light-brown. Paraphyses septate, sparingly branched, surrounded by a gelatinous matrix. Asci 65-95 × 13-18 µm, 8-spored, cylindrical, pedunclate, non-amyloid, thin-walled, slightly thicker at the flat apex, aphysoclastic, persistent, developing on an ascogenous tissue at the bottom of the locule. Ascospores 16-21.5 x 6-8 µm, ellipsoidal, 1-septate, not constricted at the septum, hyaline, appendaged, at each end with 5-8 apical appendages, appendages 11-17 µm long, bristle-like, rigid, slightly curved, in immature spores laterally attached. Asexual morph: Undetermined (Description based on Kohlmeyer and Volkmann-Kohlmeyer (1989)).
