| Thallus foliose, moderately adnate to adnate, to 5–10 cm wide. Lobes sparingly imbricate or not, flat, subirregular to sublinear-elongate, irregularly branched, 0.8–2 (–3) mm wide; central laciniae flat or absent. Upper surface yellow-green, commonly blackening towards centre as a result of dark-tipped isidia, dull, emaculate, smooth, without areolae, without soredia; isidia sparse to dense, cylindrical, simple or branched and coralloid, to 2 mm high, apices syncorticate. Medulla white. Lower surface pale brown to dark brown; rhizines sparse to moderately dense, simple, slender, concolorous. Apothecia rare, subpedicellate, 1.5–6 mm wide; disc strongly concave, becoming ±flat, shiny, dark brown; thalline exciple thin, involute at first, persistent, isidiate. Ascospores 7–12 × 5–6 µm. Pycnidia rare. Conidia bifusiform, 6–7 × 0.5 µm. CHEMISTRY: cortex K-, UV-; medulla K-, C-, KC+ rose, P-; containing usnic acid, ±loxodin, norlobaridone (major), ±scabrosin 4,4'-diacetate, ±scabrosin 4-acetate 4'-butyrate, ±scabrosin 4,4'-dibutyrate and ±scabrosin 4-acetate 4'-hexanoate; rarely contains traces of norlobariol, isonorlobaridone, norlobariol methyl ester, conorlobaridone, constipatic acid, protoconstipatic acid or unidentified compound. |  |
