| Thallus foliose, unattached or loosely adnate, forming rosettes to 0.5–2 cm wide. Lobes imbricate or not, ±separated near thallus margin, sublinear-elongate, subdichotomously to dichotomously branched, 0.2–1 (–2) mm wide. Upper surface pale yellow to pale yellow-green, weakly convex, dull, ±maculate, smooth, lacking isidia; lobe apices (and rarely margins) becoming swollen and developing terminal, subcapitate soralia; soredia farinose. Medulla white. Lower surface partly canaliculate, pale yellow to yellow-brown; rhizines sparse to moderately dense, simple or rarely sparsely branched, black. Apothecia and pycnidia not seen. CHEMISTRY: cortex K-, UV-; medulla K+ dingy brown, C-, P+ orange-red; containing usnic acid, fumarprotocetraric acid, ±succinprotocetraric acid and ±protocetraric acid (trace). | ||
