Ciri dan struktur
Apothecia developing on dead branch, elliptical or oblong-elliptical in outline, ends slightly acute to obtuse. Apothecia surface black, matt or slightly glossy, moderately raising the substratum surface, opening by a single longitudinal split that extends to the ends of the apothecium (Fig. 3a, b). Lips absent. In median vertical section (Fig. 3d), apothecia deeply embedded in host tissue, with host cells becoming filled with fungal tissue as the apothecium develops. Covering stroma (Fig. 3c) 30–45 µm thick, composed of blackish-brown to black, thick-walled cells of textura angularis towards the exterior and several layers of pale to nearly hyaline, thin-walled cells towards the interior. Along the edge of the apothecial opening, there is a flattened, 12–20 µm thick extension adjacent to the covering stroma that is composed of strongly melanised tissue with no obvious cellular structure. Basal stroma 8–18 µm thick, dark brown or blackish-brown, composed of angular to globose, thick-walled cells, 2.5–4 µm diam. A triangular space between the covering stroma and basal stroma consists of thin-walled, nearly hyaline to grey-brown cells arranged in textura prismatica. Paraphyses 1–2 µm, filiform, hyaline, septate, gradually swollen or branching once at the apex, embedded in gelatinous sheaths. Asci (103–)110–122.5 × 5.5–7 µm (x ¯ = 113 × 6 µm, n = 20), 8-spored, unitunicate, cylindrical, long stalk, thin-walled, apex truncate to somewhat round, J-, without circumapical thickening. Ascospores 55–66 × 1.5–2.0 µm (x ¯ = 61 × 1.8 µm, n = 25), fascicle, but not coiled, filiform, gradually tapering toward the ends, hyaline, aseptate, smooth-walled, straight or slightly curved, lacking gelatinous sheath.
