Sticta (Schreber.) Ach. is one of the common lichen genera in tropical and subtropical regions, but not in the Korean Peninsula. For almost two decades, no detailed taxonomic or revisionary study has been done on this genus. This study was based on the specimens deposited in the lichen herbarium at the Korean Lichen Research Institute, and the samples were identified on the basis of recent literature. In this revisionary study, a total of eight species of Sticta, including a newly recorded one are documented. These species include Sticta fuliginosa (Dicks.) Ach., Sticta gracilis (Müll. Arg.) Zahlbr., Sticta limbata (Sm.) Ach., Sticta nylanderiana Zahlbr., Sticta sublimbata (J. Steiner) Swinscow & Krog, Sticta weigelii (Ach.) Vain., Sticta wrightii Tuck., and Sticta yatabeana Müll. Arg. Detailed descriptions of S. nylanderiana, S. sublimbata, S. weigelii, and S. yatabeana with their morphological, anatomical, and chemical characteristics are provided. A key description of all known Sticta species of the Korean Peninsula is also presented. [ABSTRACT FROM AUTHOR]

Lobaria (Schreb.) Hoffm is a common foliose lichen genus found on the Korean Peninsula, yet until now, no revision study has been done on this genus. After careful examination of specimens deposited in the Korean Lichen Research Institute (KoLRI), nine distinct species of Lobaria were confirmed. Morphological characteristics such as the presence or absence of isidia, or whether or not the surface was ridged or smooth, and chemical characteristics such as the result of the medulla reaction were of significant importance in the differentiation of species. Here, we provided detailed descriptions together with a key to all the known Korean species. [ABSTRACT FROM AUTHOR]
