Racoplaca macrospora

Ciri dan struktur

Diagnosis: Differing from Racoplaca maculata (Cooke & Massee) S.H. Jiang, Lücking & J.C. Wei in the much larger, fusiform ascospores and the much larger, one-septate macroconidia. Description: Thallus subcuticular, continuous, growing along the margins and scars of leaves, lobes small, not very long, forming irregular lines, margin crenulate-laciniate, bordered by a thin, black line, dark (olive-)green, nitidous, 5–10 mm across and 10–20 μm thick. Photobiont a species of Cephaleuros, cells angular-rounded, 8–13 × 4–7 μm. Perithecia covered by thin thallus layer up to ostiole, wart-shaped, 0.2–0.45 mm diameter and 100–200 μm high, greyish to greenish black. Excipulum prosoplectenchymatous, 10–15 μm thick, colourless to brown. Involucrellum carbonaceous, 15–30 μm thick, black. Paraphyses unbranched, thin, about 1 μm. Asci narrowly obclavate, 75–100 × 7.5–10 μm, eight-spored. Ascospores biseriate or irregularly orientated, fusiform, one-septate, with distinct constriction at septum, 22.5–27.5 × 4–5 μm. Pycnidia exposed, wart-shaped, black and shiny, those producing macroconidia 0.1–0.2 mm, those producing microconidia 0.07–0.15 mm diameter. Macroconidia bacillar, one-septate, 10–15 × 1.8–2.5 μm, with 17–35 μm long appendage at both ends. Pycnidia producing microconidia appearing as tiny black points, or included in pycnidia producing macroconidia. Microconidia ellipsoid, 3–5 × 1 μm.
