<P>In the genus Xanthoparmelia, species boundaries are based on morphological and chemical features such as the presence and/or absence of secondary metabolites, diagnostic reproductive structures, isidia morphology, and color of lower surface. Two new species of Xanthoparmelia are described from South Korea, X. kolriana with cylindrical isidia containing atranorin and salazinic acid as major components in the medulla together with cortical usnic acid, while X. volcanicola is characterised by a red coloured medulla, and subglobose isidia. The characteristics of Xanthoparmelia species and their distribution in South Korea are outlined and an identification key given. Additionally, we used ITS ribosomal DNA sequences to assess the monophyly of Xanthoparmelia species from South Korea. Our results reveal that traditionally circumscribed species were not recovered as monophyletic clades. Further, we here show that ITS is insufficient to estimate a well-supported phylogenetic hypothesis, but suggests that traditional taxonomy may not reflect natural groups. This communication provides an important framework for future studies assessing species boundaries in Xanthoparmelia species in South Korea.</P>
Notes on the Lichen Genus Leptogium (Collemataceae, Ascomycota) in South Korea
Jayalal, Udeni,Jang, Seol Hwa,Yu, Nan Hee,Oh, Soon Ok,Hur, Jae-Seoun The Korean Society of Mycology 2014 Mycobiology Vol.42 No.2
Leptogium (Ach.) Gray is distributed throughout South Korea; however, for nearly two decades no detailed taxonomic or revisionary research on this lichen genus has been conducted. This study examined the specimens deposited in the lichen herbarium at the Korean Lichen Research Institute, and samples were identified using descriptions recently published in the scientific literature. In this revisionary study, a total of fourteen species of Leptogium were documented, including new records of Leptogium delavayi Hue, Leptogium denticulatum Nyl., and Leptogium trichophoroides P. M. J${\o}$rg. & A. K. Wallace. Detailed descriptions of each species are given, including their morphological, anatomical, and chemical characteristics. A key to all Leptogium species known to occur in South Korea is also presented.
Notes on the Lichen Genus Hypotrachyna (Parmeliaceae) from South Korea
( Udeni Jayalal ),( Santosh Joshi ),( Soon Ok Oh ),( Jung Shin Park ),( Young Jin Koh ),( Jae Seoun Hur ) 한국균학회 2013 Mycobiology Vol.41 No.1
Hypotrachyna (Vainio) Hale is a somewhat rare lichen genus found on the Korean Peninsula. Since it was first recorded more than two decades ago, no detailed taxonomic or revisionary study of the genus has been conducted. Thus, the present study was conducted to carry out a detailed taxonomic and revisionary study of Hypotrachyna in South Korea. This study was based on specimens deposited in the Korean Lichen Research Institute (KoLRI). Detailed taxonomic studies and a literature review confirmed the presence of seven species of Hypotrachyna from South Korea, including one new record, Hypotrachyna nodakensis (Asahina) Hale. Descriptions of each species with their morphological, anatomical and chemical characters together with a key to all known Hypotrachyna species are presented.
Lichen Mycota in South Korea: The Genus Usnea
( Udeni Jayalal ),( Santosh Joshi ),( Soon Ok Oh ),( Young Jin Koh ),( Florin Crisan ),( Jae Seoun Hur ) 한국균학회 2013 Mycobiology Vol.41 No.3
Usnea Adans. is a somewhat rare lichen in South Korea, and. in nearly two decades, no detailed taxonomic or revisionary study has been conducted. This study was based on the specimens deposited in the lichen herbarium at the Korean Lichen Research Institute, and the samples were identified using information obtained from recent literature. In this study, a total or eight species of Usnea, including one new record, Usnea hakonensis Asahina, are documented. Derailed descriptions of each species with their morphological, anatomical, and chemical characteristics are provided. A key to all known Usnea species in South Korea is also presented.
The Lichen Genus Sticta in South Korea
( Udeni Jayalal ),( Santosh Joshi ),( Soon Ok Oh ),( Jung A Kim ),( Young Jin Koh ),( Florin Crisan ),( Jae Seoun Hur ) 한국균학회 2014 Mycobiology Vol.42 No.1
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 recordedone are documented. These species include Sticta fuliginosa (Dicks.) Ach., Sticta gracilis (Mull. 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 Mull. Arg. Detailed descriptions of S. nylanderiana, S. sublimbata, S. weigelii, and S. yatabeana with theirmorphological, anatomical, and chemical characteristics are provided. A key description of all known Sticta species of the Korean Peninsula is also presented.
