Little is known about the species of Cladonia that occur in the states of Paraná and Santa Catarina, in southern Brazil. Information about the occurrence of lichens in restinga (a type of coastal vegetation in Brazil) is very scarce and there are no records from rocky shores. The main goal of the present work was to make an intensive survey of Cladonia species that grow in restinga and on the rocky shores of this region. Nine species belonging to Supergroups Cocciferae, Crustaceae and Perviae were found, and two of them were new records: Cladonia squamosa for Paraná and C. palmicola for Santa Catarina. All of the species recorded occur in restinga and seven of them are also found along rocky shores. An identification key, descriptions, comments and illustrations are provided.
