This widespread lichen is often to be found on sheltered, vertical limestone walls and monuments. The rich, reddish-pink colour attracts immediate attention. The tiny black spherical discs are rare. Vertical limestone also attracts growths of rust-coloured algae (mainly Trentepohlia) but these are never rich, reddish-pink in colour. It is abundant in suitable habitats throughout Ireland.

Key characteristics

  • It is only likely to be confused with algae belonging to the genus Trentepohlia
  • Should be looked for on vertical, shaded limestone; patches may be small sometimes as little as a few centimetres or so.
