Notes on taxonomy and distribution of some critical cyanobacterial lichens from South Korea

Nine species of the cyanobacterial lichen families Lichinaceae and Gloeoheppiaceae are reported from South Korea, all of which are new to the Korean Peninsula. One specimen is identified as a possibly undescribed species of Pyrenopsis. Problems in species taxonomy, distribution patterns such as unusual long-distance disjunctions and floristic affinities are discussed.
