Hypomontagnella submonticulosa

Ciri dan struktur

Stromata superficial, pulvinate to effused-pulvinate, up to 5 cm long × 0.4–2.5 cm wide, with inconspicuous perithecial mounds; surface Rust (39) to Bay (6) in young stromata, Brown Vinaceous (84) to blackish in mature stromata, shiny; blackish woody to carbonaceous tissue immediately beneath surface and between perithecia, KOH-extractable pigments pale Livid Violet (79) in young stromata, without apparent KOH-extractable pigments in mature stromata. Perithecia obovoid to spherical, 0.3–0.4 mm high × 0.25–0.35 mm wide. Ostioles higher than the stromatal surface, minutely conical papillate, surrounded by a black disc 100–152 μm diam. Asci 8-spored, cylindrical, with amyloid, discoid apical apparatus, 1–2 µm high × 2.5–3 µm wide, stipe up to 50 µm long, and spore-bearing portion 70–85 × 6–10 µm. Ascospores brown, unicellular, ellipsoid-inequilateral, with broadly to less frequently narrowly rounded ends, 10–13(–14) × 4–5.5 µm, with straight germ slit less than spore-length on convex side; perispore indehiscent in 10% KOH. Colonies on OA covering a 9 cm Petri dish in 2 weeks, at first whitish, becoming Pale Luteous (11) with sporulation, velvety, azonate to faintly zonate, with diffuse margins. Conidiogenous structure branching virgariella-like as defined by Ju and Rogers (1996). Conidiophores hyaline, smooth to finely roughened. Conidiogenous cell hyaline, smooth, 16–30 × 1.5–2 µm. Conidia hyaline, smooth to finely roughened, ellipsoid, 4–5.5 × 2.5–3.5 µm. This specimen from our collection shares characters with the type specimen (Ju and Rogers 1996; Lambert et al. 2019), aside from insignificant variations in the size of ascospores [10–13(–14) × 4–5.5 vs. 9–13.5 × 4–5.8 µm].
