This attractive foliose lichen is noted for its brown, round, broad lobes (distinctly more so than in P. intricata or P. lacerata) with the upper surface showing a partially ridged network surrounded by a flourish of beautiful lilac-mauve soralia occurring either as spots or growing along the developing creases. Chemically it has a distinctive C+ red medulla. In Ireland, the species is local in Counties Kerry and Donegal. In the nineteenth century the species was known to be more widespread and today should be searched for in Counties Cork, Galway, Carlow and Antrim. It is an oceanic species of mossy rocks and trees in damp woodland, particularly favouring hazel and willow.

Key characteristics

  • Elegant foliose lichen with brown, rounded lobes with a spotting of lilac-mauve soralia on the lobe surfaces and along the margins
  • The soralia and medulla turn C+ red.
