Clad. Comm.: 87, 1827. Basionym: Cenomyce straminea Sommerf. - Suppl. Fl. Lapp.): 128, 1826
Synonyms: Cladonia metacorallifera Asahina
Description: Primary thallus squamulose, persistent, the squamules up 4 mm wide, flattened, moderately divided into small, rounded lobes, dark yellowish green above, white beneath. Podetia goblet-shaped, dark yellowish green, hollow inside, with narrow cups, 4.5-7.5 mm tall, 2-4 mm wide, 1.5-2 mm thick at base, corticate, covered with numerous squamules and microsquamules, sometimes mixed with granules; basal areas and margins of cups often decorticate, with a visible blackened stereome. Apothecia scarlet red, mostly on 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 red, most frequent along the margins of cups, with a red slime. Conidia hyaline, curved. Photobiont chlorococcoid. Spot tests: chemotype a): K-, C-, KC+ pale yellow, P-, UV+ white; chemotype b): K+ yellow, C-, KC+ pale yellow, P+ yellow, UV–. Chemistry: chemotype a): usnic, didymic and squamatic acids; chemotype b): usnic, didymic and thamnolic acids. Rhodocladonic acid in apothecia of both chemotypes.
