A species separated relatively recently from P. sulcata based on a few morphological characteristics and DNA. Its distribution in Europe is poorly known since it is usually not distinguished. The lichen is common, for example, in the Iberian Peninsula, where it was described. Alike P. sulcata, it grows mainly on bark of deciduous and coniferous trees in open, well-lit habitats. Rarely, it has been recorded on rocks. Its ecology and distribution in the Czech Republic is poorly known. There have been only a few individual findings in the country so far (the Šumava Mts, the Rokycany and Třebíč regions). Due to its remarkable similarity to P. sulcata, it may be easily overlooked in the field.
