Cladonia furcata subsp. subrangiformis (Sandst.) Abbayes

Description: This subspecies is similar to C. furcata (described elsewhere). It differs in its darker thallus (green-brown to brown) shinier stalks (podetia) and whitish, chalky spots near the base of the stems. Its prostrate habit (short, calcareous turf), stunted appearance and short spiky side shoots formed at right angles to the podetia should help confirm it in the field. Mainly coastal; thinly scattered throughout Ireland.

Key Identification Features:

  • Prostrate plant with browner thallus than C. furcata and chalky spots near base of the stems
  • Usually with numerous short, spiky side shoots and on short, calcareous, rabbit-grazed turf.
