Rhizoplaca callichroa

Ciri dan struktur

Thallus saxicolous, to 4 cm across, squamulose to placodioid; squamules pruinose on the edges, more or less umbilicate when young; central squamules scattered to continuous, closely attached to the substrate, 1–2 mm across; marginal squamules larger than those in the centre, 2–4 mm across, with 1–2 mm free margin; upper surface yellowish-brown, smooth, plane to slightly convex; lower surface pale to pale brown, without rhizinose strands. Upper cortex filled with yellowish-brown granules dissolving in KOH, ca. 32 μm high; epinecral layer also filled with yellowish-brown granules, ca. 15 μm; algal layer continuous, 64–80 μm high; medulla thick, filled with grey to pale brown granules; lower cortex of free margin poorly developed, non-gelatinised, ca. 30 μm. Apothecia lecanorine, laminal, dispersed, sessile, becoming slightly constricted at the base, round to irregular, 0.5–1.5 mm; disc orange, covered with pale pruina, plane to slightly convex; thalline margin entire and thick when young, becoming thin and occasionally flexuose with age; hymenium with scattered orange granules, I+ blue, ca. 80 μm high; thalline margin with evenly thick cortex, ca. 26 μm thick; epihymenium yellowish-brown, ca. 10 μm high; subhymenium and hypothecium colourless; ascus Lecanora -type, 8-spored; paraphyses slightly branched, without anastomoses; ascospores subfusiform to ellipsoid, 9.5–13.5 × 6–9 μm. Pycnidia immersed in the thallus, with pale brown ostioles; conidia filiform, straight to slightly curved, 19–26 × ca. 0.7 μm.
