Peltula lobulata

Ciri dan struktur

Diagnosis: It is characterized by many lobules, irregularly lobed margins, and uneven surfaces. Description: Thallus saxicolous, squamulose, up to 2.5 mm in diameter, irregularly rounded, convex to flat, plenty of lobules present at mature thallus; margins rolled down and lobed, paler than thallus; upper surface is dark olive-green, colour uneven, rugose, sometimes cracked, epruinose; lower surface matt, almost black, tightly appressed to the substrate by central short umbilicus; isidia and soredia absent. Thallus 185–300 μm thick, lobules up to 125 μm thick; upper cortex not developed but with a yellowish epinecral layer, 5 μm thick; photobiont layer 56–105 μm thick, cyanobiont unicellular, cells 9.3 × 13.4 μm in diam. in clusters of 2–4 cells; medulla composed of loosely interwoven hyphae and round cells, 35–80 μm thick, hyphae 2 μm wide; lower cortex paraplectenchymatous, 30 μm thick, made up of 3–5 layers of big cells, cells 8 × 5.5 μm in size. Apothecia rare, average 1–2 per squamule, very rarely up to 5, punctiform and immersed, later up to 0.2 × 0.27 mm, thalloid rim absent. Epihymenium yellow brown; hymenium approximately 150 μm tall, paraphyses tips sometimes branched, 1.6–2.3 μm wide, I+ wine red, K−; subhymenium approximately 60–87 μm thick, IKI+ blue after K pretreatment; asci clavate to obclavate, with a lacerate gelatinous sheath, ascus 37–70 × 12–19 μm, more than 60 spores, ascus wall IKI+ blue after K pretreatment; ascospores hyaline, ellipsoid, simple, (4.7) 5.5–8.3 × 2.7–3.8 μm. Pycnidia immersed, cerebriform, ellipsoid, hyaline, 2.1–2.8 × 1.5–1.7 μm.
