| Thallus adnate, thin, rather brittle, to 5–15 cm wide. Lobes imbricate, sublinear to mostly subirregular, irregularly branched, short, 1–5 mm wide; usually with laciniae which become dense, flaring to rounded, 1–2 mm wide. Upper surface pale greenish grey, shiny, maculate, smooth to rugose-foveolate, continuous, without soredia and isidia; pseudocyphellae mainly marginal, rarely laminal, forming a nearly continuous white rim 0.1–0.2 mm wide around primary lobes and laciniae; laminal pseudocyphellae sparse and separate on older primary lobes, usually not fissuring. Lower surface sparsely to moderately rhizinate; rhizines simple to furcate to sparsely squarrosely branched, 0.5–1.5 mm long. Apothecia common, sessile to subpedicellate, 4–20 mm wide; disc generally remaining flat, sometimes cupuliform, splitting radially at maturity, very pale tan (sometimes concolorous with upper surface) to medium brown, rarely darkening; thalline exciple rugose and effigurate-pseudocyphellate. Ascospores 11–15 × 7–10 µm. Pycnidia numerous. Conidia bacilliform to weakly bifusiform, 5.5–6.5 × 1 µm. CHEMISTRY: cortex K+ yellow; medulla K+ yellow then red or K-; C-, P+ orange; containing atranorin, chloroatranorin, salazinic acid (major), consalazinic acid (minor) and with or without unidentified compound 27. | ||
