Cladonia subcervicornis (Vain.) Kernst.

Jahresber. Staatsoberrealschule Klagenfurt, 43: 25, 1900. Basionym: Cladonia verticillata var. subcervicornis Vain. - Acta Soc. Fauna Fl. Fenn., 10: 197, 1894.
Synonyms:
Distribution: N - Ven, Piem (Isocrono & al. 2006, 2006b), Lig. C - Tosc (Brackel 2015), Sar. S - Camp (Ravera & al. 2019a), Cal (Puntillo 1996).
Description: Primary thallus squamulose, prominent and persistent, forming cushions, the squamules ascending, large, 0.5-1(-3) cm long and 2-4(-5) mm wide, with an entire to weakly indented margin, bluish green to grey-green above, at first white but soon lead grey beneath at least in the lower half, often with strongly melanotic spots near the attachment point. Podetia rare, 5-6 mm tall, 1-2 mm thick, hollow inside, with funnel-shaped, rapidly flaring, irregular cups which sometimes proliferate from the centre or from the margins, lead grey to grey-green, melanotic ar base, often phyllopodiate, with a more or less continuous or areolate cortex. Apothecia rather rare, dark brown, convex, often clustered, originating from the margins of the 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, subglobose to ovoid, semi-immersed on the margins of cups, with a colourless jelly. Conidia bacilliform. Photobiont chlorococcoid. Spot tests: K+ yellow, C-, KC-, P+ red, UV-. Chemistry: fumarprotocetraric acid complex and atranorin.
Note: on siliceous rocks and on soil rich in humus in open habitats; probably more widespread in Tyrrhenian Italy. The records from Piedmont and Lombardy by Valcuvia (2002, 2002b) are rather dubious.
Growth form: Fruticose

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