Lobothallia brachyloba

Ciri dan struktur

Thallus areolate with lobate margin, tightly adnate to the substrate, up to 3 cm across, 0.6–2 mm thick. Areoles (0.5–)0.8–1.5(–2) mm wide, irregular to suborbicular, not constricted at base, interspaces between areoles mostly 0.2–0.4 mm wide. Lobes short, simple to 2–3 branched, 2–3 mm long, 0.6–1.5 mm wide at the base, 1–3 mm wide at the apex, mostly 0.6–0.8 mm thick. Upper surface flat to slightly convex, light gray with brownish tinge, thinly pruinose. Upper cortex paraplectenchymatous, even, 30–40 μm thick, with brown granules (soluble in K); epinecral layer 5–20 µm thick, with brown to black granules (insoluble in K). Algal layer 100–125(–200) µm thick, discontinuous; photobiont chlorococcoid, cells 8–18 µm diameter. Medulla 0.4–1.6(–2) mm high, filled with gray-black granules. Lower cortex absent. Apothecia cryptolecanorine (rarely elevated as lecanorine, not constricted at base), numerous, 1–8 per areole, orbicular to slightly angular, (0.1–)0.2–0.7(–1) mm diameter; disc slightly concave to flat, black, matt, epruinose to faintly pruinose; apothecial margin usually indistinct (when lecanorine, slightly elevated, 0.05–0.2 mm wide). Exciple narrow, widening to 20–30 μm in the uppermost part. Epithecium, hymenium and subhymenial layers combined 175–225 µm high; epithecium 5–15 µm high; epihymenium 15–40 μm high, with brown dark granules (mostly soluble in K), N−; hymenium 120–140 µm high, hyaline, I+ weakly bluish; subhymenial layers 60–75 μm high, hyaline, I+ blue; algal layer beneath hypothecium discontinuous; paraphyses simple, septate, submoniliform at the tips, with 2–3 uppermost cells shorter and wider than the basal cells, 3–5(–6) μm wide (basal cells ca. 2 μm wide); asci clavate, Aspicilia -type, hyaline, 8-spored, 60–70 × 15–22 µm; ascospores simple, hyaline, broadly ellipsoid, (9.0-)9.9–10.8–11.7(-12.0) × (7.0-)7.6–8.2–8.9(-10.0) µm (n = 41), l/w ratio (1.1-)1.2–1.3–1.4(-1.6), wall ca.1 µm thick.
