Ann. Bot. Fenn., 26: 160, 1989.
Synonyms:
Description: Primary thallus squamulose, the squamules middle-sized, 2-4(-5) mm long, 2-3 mm wide, variable in form, rounded or a little indented, white or often yellowish towards the base beneath. Podetia goblet-shaped, hollow inside, yellowish-green, continuously corticate in lower part, areolate in upper part, esorediate, non- or scarcely squamulose, 1-2(-3) cm tall, bearing 6-12 mm wide, regular cups flaring into a short stalk, the inner part of cups areolate, the areoles forming 0.2-0.8 flattened plates (schizidia). Apothecia frequent, scarlet red, convex, developing along the margins of cups, often coalescent into c. 3 mm wide clusters. 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 scarlet red, semi-immersed, pyriform. Conidia hyaline, curved. Photobiont chlorococcoid. Spot tests: K-, C-, KC+ yellow, P-, UV-. Chemistry: usnic, barbatic and 4-O-demethylbarbatic acids; rhodocladonic acid in apothecia and pycnidia.
