Description: Primary thallus squamulose, ephemeral, the squamules middle-sized, 1-4(-5) mm long, greenish brown to greenish grey above, pure white beneath. Podetia elongate, hollow inside, dull glaucous green, greenish grey or greenish brown in sun-forms, sometimes browned or weakly pruinose at the tips, often yellowish at the emorient bases, 5-10 cm tall, 0.5-4(-5) mm thick, cupless or with narrow (1.5-5 mm wide) cups, esquamulose or sparsely squamulose in lower parts, the cortex subcontinuous to checkered-areolate, the areoles often separated by a network of white medullary interspaces. Apothecia rare, brown to almost black, convex, developing along the margins of cups. Asci 8-spored, clavate, thickened at apex, with a K/I+ blue tholus and a K/I+ strongly blue outer gelatinous sheath, Cladonia-type. Ascospores 1-celled, hyaline, ellipsoid. Pycnidia dark, pyriform, semi-immersed along the margins of the cups, with a colourless jelly. Conidia bacilliform. Photobiont chlorococcoid. Spot tests: K+ instantly yellow, C-, KC-, P+ red; yellow pigment at the base K+ red. Chemistry: atranorin, fumarprotocetraric acid, and terpenoids.
