The Parmeliaceae are a family of lichens (or, more strictly, a family of fungi, one of the symbionts that constitute the lichens). It is the largest family of lichen-forming fungi, with over 2000 species and 83 genera. Species of this family have a cosmopolitan distribution and may be found in a wide range of climatic regions. Based on analysis of the sequences ssu mitochondrial DNA sequences, the Parmeliaceae are a monophyletic group.
