Abstract: [Analysis including ITS rDNA sequence data revealed the " ... sexually and vegetatively dispersed entities in an anticipated "species pair" (Roccella galapagoensis/R. lirellina) actually form several distinct monophyletic genotypes, here interpreted as species in which sexual reproduction has been repeatedly evolved." Taxonomic treatment of 5 species; key. New: Roccella albida Tehler sp. nov. (Galapagos Islands).]
