This exotic epiphyte has a red-brown, ridged thallus (duller brown when wet) with scattered bright yellow soralia peppering the lobes and the lobe margins. The medulla is white, Pd+ orange. It occurs mainly on mossy trees in boggy sheltered woodland in Counties Kerry, Galway and Clare (the Burren), but was once more widespread.

Key characteristics

  • Growing to 2-3cm diam., on mossy trees in old, coastal woodland; the red-brown thallus has a network of ridges across the surface of the lobes
  • Bright yellow soralia occur initially as spots but then expand into lines; the white medulla is Pd+ orange which separates it from P. aurata.
