Upper surface yellow-green, darkening to deep olive-brown or blackish in older lobes, dull, emaculate, without soredia; older lobes becoming cracked and often forming areolae 0.2–0.5 mm wide in thallus centre; areolae appearing as fragmentary lobules in poorly developed specimens; isidia dense, cylindrical, simple or sparingly branched, fragile, small (0.1–0.2 mm); isidia apices syncorticate, solid, brown. Medulla white. Lower surface pale tan; rhizines sparse, simple, robust, concolorous. Apothecia rare, subpedicellate, to 4 mm wide; disc weakly concave, becoming flat or ±undulating, brown to dark brown; thalline exciple thin, entire, persistent, densely isidiate. Ascospores 7–9 × 4–5 µm. Pycnidia not seen. CHEMISTRY: cortex K-, UV-; medulla K-, C-, KC-, P-; containing usnic acid, scabrosin 4,4'-dibutyrate, scabrosin 4-acetate 4'-butyrate, scabrosin 4-acetate 4'-hexanoate and ±scabrosin 4,4'-diacetate. | ||
