Cladonia subcervicornis forma.

     Primary thallus persistent, scaly, cushion-shaped, squamules erected, 4-6 x 2-4 mm thick with a lobed margin not or little striated and sometimes brownish. Upper surface grey-green, green-blue, sometimes more or less spotted and arachnoid ("sky of snow") and sometimes powdered, lower surface whitish more or less blackish towards the base. Podetions rare, thin and simple with a corticate or scaly surface, without a really well-formed cup at the top. Apothecia rare, globose at the top of the podetions, brown. Pycnidia on the lobes, globose to conical, black. C-, K+ yellow, KC+/- yellow or KC-, P+ reddish, UV-. Taxon coming from the ground or in the cracks of acidic rocks here in the cracks of Armorican sandstone rocks at the top of a very exposed cliff.

_ This form differs from the type by the margin of its scales not distinctly striated and its simple and slender podetions without a clear cut at the top.

Cf. Cladonia strepsilis C+ emerald green.

Cf. Cladonia firma whose lower surface of the scales is felted and purplish.
