Description: Primary thallus squamulose, usually persistent, the squamules large, 0.5-2.5 cm long, 2-7 mm wide, coarse, with broad and rounded divisions, grey-green to glaucous green above, white beneath, often darkened but not melanotic at base. Podetia robust, hollow inside, greyish-green, somehow glaucescent, 0.5-7 cm tall, 2-3(-5) mm thick, simple to irregularly branched, the terminal branches usually subulate, cupless or with irregular cups, esorediate, with a smooth to areolate cortex, the areoles separated by white lines and cracks, also inside the cups. Apothecia rare, brown, convex, often clustered. 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 common both on basal squamules and on tips of podetia, sessile, with a colourless jelly. Conidia bacilliform. Photobiont chlorococcoid. Spot tests: K+ yellow (rarely K-), C-, KC-, P+ red (rarely P-), UV-. Chemistry: atranorin (rarely scarce or absent) and fumarprotocetraric acid (almost always present).
