Description: Primary thallus squamulose, persisting, the squamules large, up to 1 cm long, 3-4 mm wide, grey green above, white and slightly veined beneath, rarely sorediate at margins. Podetia goblet-shaped, hollow inside, greyish, 1-2(-3) cm tall, with a broad (to 8 mm), regular cup, flaring to a 2-9 mm long stalk which is usually longer than the diameter of the cups. Surface of podetia continuously and rather smoothly corticate in lower and middle parts, farinose-sorediate in upper parts and in the interior of cups, the soredia 20-45 μm in diam. Apothecia very rare, developing on short proliferations on the margins of cups, brown. 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 conical, located at the margin of cups, with a colourless jelly. Conidia bacilliform. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P+ red.
