Thallus firmly attached, to 3 cm wide sometimes to 12 cm. Lobes few to numerous, discrete, contiguous or overlapping; main lobes 4–6 mm wide, sausage-shaped, attenuated or segmented; lateral lobes irregularly spaced, short, 1.5–2.5 mm wide, at the centre elongating and overlapping, often forming a confused mass, all lobes highly inflated, convex to ±flattened. Cavity tomentose, jet black. Upper surface rugose-reticulate, without blotches or soredia, pale grey. Perforations scarce on main lobes, more frequent on young lateral lobes, oval, 1.5–2.5 mm wide, elevated, conical; margin ±smooth, shining. Apothecia scattered or clustered, laminal, 3–5 mm wide, sessile or rarely short-pedicellate; disc epruinose, dark brown; exciple strongly swollen, plicate to ridged becoming inflated-crenulate. Ascospores 2 per ascus, 50–65 × 35–45 µm; wall 3–5 µm thick. Pycnidia numerous; ostiole black. Conidia 6–7 × 0.5 µm. CHEMISTRY: cortex K+ yellow (atranorin); medulla K+ yellow-red, C-, KC+ red, P+ orange (stictic, norstictic (trace), menegazziaic, cryptostictic, constictic acids and accessory substances). | ||
