This is a list of species in the lichen genus Caloplaca . Although there were estimated to be more than 500 species in 2008, [1] the family Teloschistaceae has undergone major revisions since then. Several molecular phylogenetic studies have been published that have established a phylogenetic framework to more appropriately classify lichens that were previously grouped in Caloplaca. [2] [3] [4] [5] As of December 2023 [update] , Species Fungorum (in the Catalogue of Life) accepts 173 species of Caloplaca. [6]
