Cladonia humilis (With.) J.R. Laundon
Lichenologist, 16: 220, 1984. Basionym: Lichen humilis With. - Bot. Arrang. Veget. Gr. Br., 2: 721, 1776.
Synonyms: Cladonia conoidea Ahti
Description: Primary thallus squamulose, persistent, the squamules 3-10 mm long, 1-3 mm wide, rounded to sparingly incised, white and often slightly veined beneath, rarely sorediate at margins. Podetia goblet-shaped, hollow inside, greyish-green, corticate only at base, generally esquamulose, 4-11 mm tall, with regular, 3-4(-8) mm wide cups abruptly tapering to a very stalk which is shorter than the diameter of cups (the cups appearing subsessile), continuously and smoothly corticate, finely pruinose from the base to the cups, but farinose-sorediate in upper parts and inside the cups, the soredia 20-60 μm in diam. Apothecia rare, brown, convex, stipitate along the margins of cups. 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, ovoid, developing along the margins of cups, with a colourless jelly. Conidia hyaline, curved. Photobiont chlorococcoid. Spot tests and chemistry: four chemotypes (all of them C-, KC-, UV-): 1) K+ yellow, P+ red (atranorin, fumarprotocetraric acid complex), 2) K- or K+ yellowish slowly turning brown, P+ red (bourgeanic and fumarprotocetraric acids), 3) K+ yellow, P+ red (atranorin, fumarprotocetraric and bourgeanic acids), 4) K- or K+ yellowish slowly turning brown, P+ red (fumarprotocetraric acid complex). Chemotype 1) is the most frequent.
Growth form: Fruticose
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)
Most common in areas with a humid-warm climate (e.g. most of Tyrrenian Italy)
Pioneer species
