Medulla white. Lower surface black, with brown marginal zone; rhizines sparse to moderately dense, simple, black. Apothecia rare, 2–5 mm wide; disc concave, red-brown to dark brown; thalline exciple sorediate. Ascospores 8–11 × 5–7 µm. Pycnidia rare. Conidia weakly bifusiform, 6–8 × 1 µm. CHEMISTRY: cortex K+ yellow; medulla K-, C-, KC-, P-; containing atranorin, chloroatranorin, divaricatic acid (major), nordivaricatic acid (trace) and stenosporic acid (trace). | ||
