Abstract: Lichens of Mikura-jima Island, Izu Islands, central Japan, were investigated. As the results of taxonomic study, 78 taxa (77 species and 1 variety) were recognized from the island. Among them, Graphis mikuraensis Y. Ohmura & M. Nakan. is described as a new species. Lepraria finkii and L. lobificans, based on the emended species concept, were confirmed to occur in Japan. A new combination, Rhabdodiscus inalbescens (Nyl.) Frisch is proposed. Phytogeographic discussion is made for the listed species. The lichen flora of Mikura-jima Island is characterized by the high percentage of pantemperate element species together with tropical and subtropical species. A remarkable range extension is noted for Physma radians, and the find represents the northernmost locality for this pacific element species. Nipponoparmelia laevior, which was common before 1981, may have become extinct or drastically reduced in this island during the past 30 years.
