Lichina is a genus of lichen-forming fungi in the family Lichinaceae. The genus contains four marine species. These cyanolichens include species such as L. pygmaea or L. confinis, in which the associated cyanobiont has been assigned to the genus Rivularia. Furthermore, evidence of a high specificity of each mycobiont towards particular cyanobiont lineages in both species has been detected.
