This yellow-green Cladonia lichen, the scales of which have a lower, pale yellow side, can form dense mats of scaly squamules across large areas. It grows best on short, dry, calcareous soils (sandy dunes, stable shingle, rock crevices and cliff tops) by or near the sea, rarely inland. The dominant feature is the squamules which can grow to nearly 2cm high. These are rather indented and ragged which, when dry, curl back to show their undersides. Throughout Ireland.

Key characteristics

  • Thallus of ragged, yellow-green scaly squamules, pale-yellow below
  • On short turf and in soily crevices of sea cliffs.
