After a discussion of changing generic concepts in the parmelioid lichens, a checklist with the current species placements is presented. Twenty-five genera and 143 species are accepted for Europe, of which 17 genera and 112 species belong to the monophyletic parmelioid clade. The individual countries from which species are reported are provided, along with references to key publications. Synonyms used at species rank in Europe are cross-referenced, and the dates of publication of all names are provided. One new combination is made: Xanthoparmelia pulvinaris (syn. Parmelia pulvinaris, X. pseudohungarica).
