The richly branched white-grey to grey-green thallus of this lichen forms loosely-compact tufts several centimetres in diameter. The ‘reindeer lichen’ branch tips have no preferred orientation so point in all directions. It has the pliability of a bathroom sponge when wet but becomes brittle when dry. It is common among moorland vegetation, frequently attaching to pockets of soil on outcrops and boulders in upland areas.

Key characteristics

  • Uniformly white-grey or grey-green throughout
  • Branch tips spread in all directions.
