The aim of the paper is to evaluate the diversity of all known lichenized and lichenicolous fungi
of the Turkish provinces, their similarities being calculated and to determine their distribution
in the geographic and phytogeographic regions of Turkey. The records of lichenized fungi in "A
Checklist of the Lichens of Turkey" were evaluated, together with new country and province
records from 2015 to 2020. A total of 1765 lichenized fungi were evaluated from the 81
provinces. The geographical regions of Turkey were divided into three main groups according
to the similarity in species diversity (1) Aegean, Mediterranean and Marmara, (2) Central,
Eastern and Southeastern Anatolia, and (3) the Black Sea region. The phytogeographical
regions of Turkey were divided into two main groups (1) Euro-Siberian and Mediterranean and
(2) Irano-Turanian. The very heterogeneous intensity so far of the research on lichens in the different provinces of Turkey causes only a weak correlation of the distribution of lichens with the
geographic and phytogeographic regions.
