Medulla white. Lower surface pale ivory to pale brown, blackening near lobe apices; rhizines moderately dense, simple, brown to black. Apothecia sessile, to 7 mm wide; disc becoming flat, brown to dark brown; thalline exciple involute, becoming undulating. Ascospores 9–10 × 6 µm. Pycnidia common. Conidia bifusiform, 6 × 0.5 µm. CHEMISTRY: cortex K-, UV-; medulla K+ yellow then dark red, C-, P+ yellow-orange; containing usnic acid, norstictic acid, connorstictic acid, ±salazinic acid, ±constipatic acid and ±protoconstipatic acid. | ||
