Brief description
Characterised by the lignicolous (rarely saxicolous) habit; cylindrical isidia; and lecanoric acid in the medulla.
Distribution
North Island. South Island.
Known also from Australia and New Caledonia.
Habitat
On bark and decorticated wood, rarely on rocks, coastal and inland.
Detailed description
Thallus closely attached, 2–10 cm diam. Lobes imbricate, variable, sublinear–elongate to subirregular and apically rounded, sometimes subdichotomously branching, 1–3 mm wide, cilia sparse to moderately common, 0.1–0.5 mm long, black. Upper surface pale-grey to greenish grey, plane to convex, glossy, emaculate, smooth, isidiate, soredia absent. Isidia scattered to common, cylindrical, erect, often branched, less than 0.5 mm tall. Lower surface black, rhizines common, simple, black. Apothecia rare, sessile, 1–4 mm diam., exciple isidiate. Ascospores broadly ellipsoidal, 9–13 × 5–8 μm. Pycnidia rare, Conidia cylindrical, 3–4 × 1 μm.
Chemistry: Cortex K+ yellow; medulla K−, C+ red, KC+ red, Pd−; containing atranorin, chloroatranorin, lecanoric acid (major) and occasionally orsellinic acid (tr.).
