Peltula submarginata

Ciri dan struktur

Diagnosis: This species is similar to P. marginata but differs in the epinecral layer covering the whole surface and the underlying algal layer surrounding the whole perimeter of squamules, larger conidia, and absence of lower cortex. Description: Thallus saxicolous, squamulose-subfruticose, clavate when young and later peltate; lobes circular to elliptical, top almost flattened, 0.3–0.8 (–2) mm in diameter, fertile lobes bigger than sterile lobes; margin entire; upper surface yellowish olive with black–brown border, smooth, epruinose; isidia and soredia absent, attached the substrate by stalk or umbilicus. Lobes 230–370 μm thick, cortex not developed but with a yellowish epinecral layer, up to 8 μm thick; algal layer encircled, 42–96 μm thick, cyanobiont unicellular, cells 8.5–10.6 μm in diameter, in clusters of 2–4 cells; medulla with rare hyphae and hollow areas in the central part, hyphae 2.2–2.4 μm thick. Apothecia 1–7 per lobe, completely immersed, discs punctiform, black. Epihymenium light yellow; hymenium up to 180 μm tall, I+ wine red, K-, paraphyses 1.7 μm wide; subhymenium up to 85 μm tall, IKI+ blue after K pretreatment; asci clavate to obclavate, with a lacerate gelatinous sheath, 112–128 × 18–20.5 μm, more than 100-spored, ascus wall IKI+ blue after K pretreatment; ascospores hyaline, ellipsoid, simple, 5.5–6.2 × 4.2–5.4 μm; subhymenium c. 85 μm thick. Pycnidia immersed, cerebriform; conidia ellipsoid to short bacilliform, hyaline, (2.1) 4.1–6.2 × 1.4–2.3 μm.
