Lichenologist, 16: 223, 1984. Basionym: Lichen peziziformis With. - Bot. Arrang. Veget. Gr. Brit.: 720, 1776.
Synonyms: Cladonia capitata (Michx.) Spreng.; Cladonia leptophylla (Ach.) Flörke; Cladonia leptophylloides Harm.
Distribution: N - TAA (Watson 2014), Lomb (Ravera & al. 2016, Gheza 2018), Piem (Ravera & al. 2016), Lig (Giordani & Incerti 2008). C - Tosc (Gheza & al. 2020). S - Cal (Burgaz & al. 2020)
Description: Primary thallus squamulose, persistent, the squamules very small, 1.2-2 mm long, 1.4-2 mm wide, granule-like to rounded and ear-shaped, with a more or less entire margin, often contiguous and forming flat crusts of convex areoles, yellowish green on upper side, white beneath. Podetia uncommon, pale greenish grey, 0.5-1.5(-2.5) cm tall, 0.3-0.8(-1.5) mm thick, hollow inside, usually simple or with a few apical branchlets, blunt and cupless, longitudinally grooved and cracked, almost continuously areolate-corticate and verruculose, sometimes sparsely squamulose at base. Apothecia frequent, brown, convex, terminal, often coalescing into 1-3 mm wide aggregations. 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, subsessile, developing on the primary squamules, with a colourless jelly. Conidia bacilliform. Photobiont chlorococcoid. Spot tests: K- or K+ dirty brown, C-, KC-, P+ rapidly red, UV-. Chemistry: fumarprotocetraric acid complex.
Note: a mainly temperate lichen found on soil in open woodlands (oak, pine) and Calluna-heaths, in areas with siliceous substrata, perhaps overlooked in Italy.
Growth form: Fruticose

Substrata: soil, terricolous mosses, and plant debris
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly sexual
Most common in areas with a humid-warm climate (e.g. most of Tyrrenian Italy)
