An epiphyte, scattered in the Czech Republic, characterized by tightly adpressed lobes with brown epruinose margins and mainly punctiform laminal soralia. Its ecological requirements are very similar to P. jeckeri and they often grow together. The species grows on acidic to subneutral bark of deciduous trees and shrubs on well-lit stands in open habitats or forests, from lowlands to mountains. Its centre of distribution is at lower elevations. Its distribution area lies in temperate and tropical areas of Eurasia, Africa and Australasia. It was not distinguished from P. jeckeri in the past, so, revision of herbarium material is necessary to determine its historical occurrence in the Czech Republic.taxonomic classification:
