This species has recently (2010) become segregated from P. reticulatum (described elsewhere) on the basis of the following characteristics (i) the lobes have a broad zone close to the edge which lacks rhizines, (ii) has a thicker thallus with a generally thickened margin, (iii) does not have thin upright lobes capped with soralia. Little is known of the relative distribution of the two species in Ireland. In Scotland, P. pseudoreticulatum has proved to be the commoner.

Key characteristics

  • Lobes with broad marginal zone lacking rhizines
  • Thallus thicker, with thicker margin.
