Abstract
As part of an ongoing comprehensive inventory of the Galapagos lichen flora, all species in the Graphidaceae from the archipelago have been revised using both historic and recent collections. A total of forty-two species is reported here, of which thirty-four were previously unknown from the archipelago and two are described as new to science: Graphis pedunculata, and Phaeographis striata. The new combinations Carbacanthographis saxiseda, Carbacanthographis saxorum and Phaeographis major are made. Four previously reported species are based on misidentifications and thus removed from the checklist. Detailed descriptions are presented that include diagnostic characteristics to distinguish similar species. An identification key to all Galapagos Graphidaceae is provided and a preliminary assessment discusses known distribution and ecology for each of the species. Principal components analysis was used to assess ecology for thirty-nine species.
