Eleven species of Ramalina (R. australiensis, R. canariensis, R. celastri, R. exiguella, R. geniculata, R. leiodea, R. luciae, R. meridionalis, R. microspora, R. pacifica and R. peruviana) are accepted for the Kermadec Islands. The northern Kermadec Islands had the greatest diversity of species (eleven species) while the southern Kermadec Islands had collectively five species. These were distributed as follows (islands arranged from north to south): northern Kermadec Islands (the Herald Islets (six species), the Meyer Islands group (two species), Raoul Island (nine species)); southern Kermadec Islands (Macauley Island (six species), Curtis Island (one species), Cheeseman Island (one species), L%92Esperance (two species)). Ramalina leiodea is a new addition to the mycobiota of the New Zealand Botanical Region and R. canariensis and R. meridionalis are new records for the Kermadec Islands, and a significant easterly extension for R. meridionalis.
