Description: Primary thallus squamulose, persistent or evanescent, the squamules middle-sized, divided, 2-8 mm long, 1-3 mm wide, yellowish green on upper side, whitish beneath (often orange-yellow near the attachment point). Podetia slender, hollow inside, 1-2(-3) cm tall, 0.5-2 mm thick, subulate when young, simple or sparingly branched, the tips blunt, later often with narrow, irregular, up to 5 mm wide cups, the margins proliferating or dentate; surface glaucous green to greenish grey, corticate only at base and inside the cups, squamulose especially toward the base, farinose- to granulose-sorediate in upper parts, the soredia 30-70 μm in diam. Apothecia scarlet red, often compound, at the margins of cups or terminal. 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 at the margins of cups, with a red jelly. Conidia hyaline, curved. Photobiont chlorococcoid. Spot tests: K+ yellow, C-, KC-, P+ yellow, UV-. Chemistry: thamnolic acid, rarely with additional small amounts of usnic acid; rhodocladonic acid in apothecia and pycnidia,Note: a cool-temperate to boreal-montane, circumpolar lichen found on organic soil and rotting wood in woodlands, more rarely on bark, on the basal parts of old trunks; certainly widespread in the Alps, becoming much rarer southwards, where it is mostly confined to old Castanea-stands.
Growth form: Fruticose
Substrata: lignum, soil, terricolous mosses, and plant debris
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)
Most common in areas with a humid-warm climate (e.g. most of Tyrrenian Italy)
