This rare, foliose lichen is very similar to P. norvegica (described elsewhere), but differs in the C- medulla and the smooth, upper surface of the lobes (they are ridged in P. norvegica). It has marginal, pale grey, farinose soralia. By contrast P. lacerata has cylindrical isidia. In Ireland, it is known from Counties Kerry and Kilkenny but was previously more widespread. It grows on shaded, mossy trees in old woodlands and on large boulders in or near upland tarns and loughs.

Key characteristics

  • Lobes with smooth upper surface and C- medulla (C+ red in P. norvegica)
  • Lobe margins sorediate (not isidiate), that is, with tiny blue-grey granules not cylindrical, stick-like projections.
