Description: Primary thallus squamulose, persistent or evanescent, the squamules small, up to c. 3 mm long, incised, greenish to pale brownish grey above, white beneath. Podetia elongate, hollow inside, pale brownish grey, (1-)3-5 cm tall, 1.5-2 mm thick, simple or sparingly branched, with pointed apices, more rarely with irregular small cups, often corticate and squamulose in lower half (the cortex verrucose-granular), granulose-sorediate in upper part, the soredia (20-)30-60 μm in diam. Apothecia rather rare, terminal, 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. Spores 1-celled, hyaline, ellipsoid. Pycnidia brown, at the tips of podetia or rarely on the margins of squamules, with a colourless jelly. Conidia cylindrical. Photobiont chlorococcoid. Spot tests: podetia K-, C-, KC-, P+ red or P-, UV+ white or UV-. Chemistry: homosekikaic and sekikaik acids, sometimes with additional fumarprotocetraric acid.
Note: a mainly temperate, probably holarctic species described from Italy, found on mineral clay and base-rich soil, mostly in slightly disturbed habitats such as on track sides and clearings of light forests and heaths. To be looked for in central and southern Italy. For the differences towards C. subulata see Pino-Bodas & al. (2010b).
Growth form: Fruticose

Substrata: soil, terricolous mosses, and plant debris
Photobiont: green algae other than Trentepohlia
