To determine whether  Corallina chilensis  is a distinct species or a variety (i.e.  C. officinalis  var.  chilensis ) of the generitype of  Corallina , molecular phylogenetic analyses were performed using  psb A, COI-5P,  rbc L, or some combination of these gene regions from 75 voucher specimens representing  Corallina  collections from around the world. Names were applied by comparing these DNA sequences with sequences obtained from type specimens, including a 263 bp  rbc L sequence from an isotype of  C. chilensis  collected by Darwin ( C. Darwin 2151 ) from Valparaiso, Chile. DNA sequences from the  C. chilensis  isotype matched unnamed coralline DNA sequences from British Columbia, Canada, and previously published DNA sequences from the northeast and southeast Pacific. The clade containing the isotype of  C. chilensis  was distinct from  C. officinalis  specimens in phylogenetic analyses. Although morphologically variable, fronds of  C. chilensis  from British Columbia populations matched Kützing’s original description of  C. officinalis  var.  chilensis . These data support the conclusion that  C. chilensis  is a distinct species, not a variety of  C. officinalis , and is distributed in both hemispheres. While this study strongly supported  C. chilensis  as a distinct species, phylogenetic relationships among  Corallina  species remain elusive because individual gene trees are not congruent.
