• Cladonia cervicornis ssp. cervicornis (Ach.) Flot., 1849

There are no records for this species at present.

This is a common species of sandy, heathy places and peaty moors away from blanket bog. The thallus consists of small, green, upright squamules that have a notched outline, and are white with a hint of mauve on the underside. The short stalks (podetia) do not produce tiered layers as in ssp. verticillata. It is relatively frequent in suitable habitats throughout Ireland.

Key characteristics

  • The white undersurface and notched edge to the squamules help to indicate this species
  • The similar Cladonia subcervicornis is a much larger, clump-forming species with a blue-green, less incised upper surface. It is more frequently seen on acid rocks, though may occur on soil.
