Description: Primary thallus squamulose, the squamules middle-sized (1-3 mm long and broad), most often ephemeral, brownish green above, white beneath. Podetia branched, hollow inside, brown, stout, to 10 cm tall (usually less), forming irregular tufts, with pointed apices and a smooth to wrinkled surface, non- or very sparsely squamulose, with evident, convex, white medullary outbursts at the base. Apothecia rare, dark brown, convex. 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 dark, semi-immersed on the tips of podetia, with a colourless jelly. Conidia cylindrical. Photobiont chlorococcoid. Spot tests: K- or K+ yellowish, C-, KC-, P+ red. Chemistry: atranorin and fumarprotocetraric acid.
Note: a mild-temperate lichen found on mineral calciferous soil, often amongst bryophytes. This taxon has so far no valid name at subspecific rank, and recent molecular data do not support its separation from C. furcata (Pino-Bodas & al. 2015) so that it could be better treated at the level of forma (Ahti in litt.), but the epithet subrangiformis is a later homonym for f. subrangiformis Vain. ex Zahlbr. Pending further study, I still maintain it here, albeit under an invalid name.
