Peltula pseudoboletiformis

Ciri dan struktur

Diagnosis: This new species is different from the similar species P. boletiformis in more yellow–green umbilici and larger conidia. Description: Thallus saxicolous, squamulose-subfruticose, loosely or tightly clustered, up to 1.5 mm in diameter, 2 mm high, stalk 0.9 mm long in average, twisted, orange to tan; lobes circular, elliptical to angular and irregular, top almost flattened, margin entire; upper surface dark olive-green, smooth, epruinose; attached the substrate by umbilicus, isidia and soredia absent. Lobes 350–600 μm thick, upper cortex not developed, with a thin yellowish epinecral layer, 5–8 μm thick; the algal layer of immature thalli 57.5–67.3 μm thick, medulla with interwoven hyphae and small air spaces and lower cortex not clear, made up of several layers of circular cells; later algal layer encircled, 119–240 μm thick, algae in clumps of 1–4 cells, cells up to 13 × 15 μm in diameter, medulla with rare and loose hyphae and big hollow areas, hyphae 2.5–3.3 μm wide. Apothecia 1 or 2 per squamule, immersed and punctiform. Epihymenium yellow; hymenium 95–215 μm tall, paraphyses 1.5–2 μm wide, I+ wine red, K-; subhymenium up to 100 μm tall, IKI+ blue after K pretreatment; asci clavate to obclavate, 70–95 × 18–20.5 μm, with a lacerate gelatinous sheath, more than 100 spores, ascus wall IKI+ blue after K pretreatment; ascospores hyaline, ellipsoid, simple, 4.5–5.5 × 3–3.8 μm. Pycnidia immersed, cerebriform. Conidia ellipsoid, hyaline, 3.5–4.1(4.5) × 1.6–2.3 μm.
