The Lichen Genus Parmotremain South Korea

AbstractParmotremaA. Massal. is a common lichen genus scattered throughout the Korean Peninsula; however, no detailed taxonomic or revisionary study of this genus has been conducted for nearly two decades. Therefore, this study revised the taxonomy of this genus based on specimens deposited in the lichen herbarium at the Korean Lichen Research Institute and samples were identified using recent literature. In this revisionary study, a total of eighteen species of Parmotremaincluding eight new records [Parmotrema cetratum(Ach.) Hale, Parmotrema cristiferum(Taylor) Hale, Parmotrema grayanum(Hue) Hale, Parmotrema defectum(Hale) Hale, Parmotrema dilatatum(Vain.) Hale, Parmotrema margaritatum(Hue) Hale, Parmotrema pseudocrinitum(Abbayes) Hale, and Parmotrema subsumptum(Nyl.) Hale] are documented. Detailed descriptions of each species with their morphological, anatomical and chemical characteristics are also given and a key to the known Parmotremaspecies of the Korean Peninsula is presented.
