Cladonia rei Schaer.
Lich. Helv. Spicil., 1, 1: 34, 1823.
Synonyms: Cladonia fimbriata var. nemoxyna (Ach.) Coëm.; Cladonia nemoxyna (Ach.) Arnold
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.
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)
