L. canariensis L. confinis L. intermedia L. pygmaea Lichina is a genus of lichen-forming fungi in the family Lichinaceae.

They often create distinguishable bands in the intertidal and supralittoral zones of rocky coastal areas in temperate and cold regions of both hemispheres.

They typically grow on rocky shores, with different species occupying distinct zones based on their tolerance to submersion and sea spray.

The current geographic distribution of Lichina species is believed to be the result of long-distance dispersal events across ocean basins, rather than ancient vicariance.

Several species previously included in the genus, such as L. antarctica, L. minutissima, L. tasmanica, and L. willeyi, are now considered to be phylogenetically distinct from the core Lichina group.
