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 hyaline, curved. 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. Spier & Aptroot (2007) considered it as a synonym and chemotype of C. subulata (but see Pino-Bodas & al. 2010b).
Growth form: Fruticose

Substrata: 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)
