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.

본 연구는 환경조건에 따른 지의류분포에 대한 기초 자료를 얻고자 수시로 해수와 접하는 지역의 해안가 암석과 해안에서 약 20 m 이상 떨어진 곳에 위치한 노지암석에서 살아가는 지의류를 대상으로 처음 수행되었다. rDNA ITS clone 유전자의 염기서열 및 형태학적 분석을 기초로 하여 비교 분석한 결과 해수와 직법 접하는 곳에 위치한 암석에서는 9과(family) 15 속(genus)에 속하는 지의류가 분포되어 있었고, 노지암석에서는 10과 14 속에 속하는 지의류가 분포되어 그 다양성에 있어 큰 차이가 없었다. Parmeliaceae 과에 포함된 것 중 엽상형(foliose)인 Phaeophyscia, physcia, Pyxine와 Parmeliaceae과에 속하는 Xanthoparmelia가 해안가 암석에 분포하는 대표적인 지의류로 나타났고, 수지상(fruticose) 지의류로는 Ramalinaceae과에 속하는 Ramalina 속 2종이 유일하게 분포하고 있음이 밝혀졌다. 가상형 (crustose) 지의류는 Lecanora속이 대표적인 해안가 암석에 분포하는 지의류로 나타났다. 반면, 노지암석위의 흙이나 이끼 낀 곳에서 발견되었으나 해안가 암석에서 발견되지 않은 지의류로는 엽상형인 Cladonia, 수지상 지의류인 Sterocaulon, 가상형 지의류인 Porpidia로 조사되었다. 가상형(crustose) 지의류인 Caloplaca, Candelaria, Dirinaria, Graphis, Rhizocarpon, Pertusaria 등이 해안가 암석에 분포하고 있음이 확인되었으나 매우 드물게 나타났으며 이들 지의류 모두는 해안가에서 비교적 멀리 떨어진 노지암석에서 대부분 분포하고 있음이 밝혀졌다.

We performed a taxonomic study on two species of the genus Bryoria from the Sino-Himalayas, SW-China. B, nadvornikiana is new to China and B. furcellata is new to Yunnan and Sichuan provinces in the Sino-Himalayas. Morphology, habitat, distributions and chemistry of the two species are discussed.

Myelochroa (Asahina) Elix & Hale is a common foliose lichen genus found on the Korean Peninsula. Since it was first recorded nearly two decades ago, no detailed taxonomic or revisionary study of the genus has been conducted. Thus, the current study was conducted to carry out a detailed taxonomic and revisionary study of Myelochroa 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 twelve species of Myelochroa from S. Korea, including one new record, Myelochroa xantholepis (Mont. & Bosch) Elix & Hale. Descriptions of each species with their morphological, anatomical and chemical characters together with a key to all known Myelochroa species are presented.

Detailed descriptions of five species of the lichen genus Canoparmelia Elix & Hale. are presented. Until now, three species of the genus Canoparmelia, including C. apata (Krempelh.) Elix & Hale, C. owariensis (Asah.) Elix, and C. texana (Tuck.) Elix & Hale have been reported in South Korea. Canoparmelia carneopruinata (Zahlbr.) Elix & Hale, C. crozalsiana (de Lesd.) Elix & Hale, and C. ecaperata (M$\ddot{u}$ll. Arg.) Elix & Hale are new to the South Korean lichen flora. An artificial key is provided for all species of Canoparmelia, including the three new records.

In previous studies investigating the genus Xanthoparmelia, thirteen different species have been reported from South Korea alone. However, there currently has been no revisional study performed until now. To explore the genus Xanthoparmelia, a phenotypic analysis was performed based on morphological, anatomical and chemical characters, while an investigation of Xanthoparmelia phylogeny was based on nuclear ribosomal (nr) DNA ITS sequences. A thorough examination of the specimens deposited in the Korean Lichen Research Institute (KoLRI) confirmed that eight species of Xanthoparmelia occur inside South Korea. Our analysis further confirmed the colors of the lower surface and medullar chemistry are important taxonomic characters in Xanthoparmelia. This study also presents a detailed description of each species and a key to the genus.

Korean species of the genus Myelochroa are revised taxonomically and the following eight species are recognized: M. aurulenta (Tuck.) Elix & Hale, M. entotheiochroa (Hue) Elix & Hale, M. galbina (Ach.) Elix & Hale, M. hayachinensis (Kurok.) Elix & Hale, M. irrugans (Nyl.) Elix & Hale, M. leucotyliza (Nyl.) Elix & Hale, M. metarevoluta (Asahina) Elix & Hale and M. perisidians (Nyl.) Elix & Hale. Myelochroa ibukiensis K.H. Moon et al. is reduced to a synonym for M. aurulenta. Myelochroa denegans (Nyl.) Elix & Hale, M. indica (Hale) Elix & Hale and M. xantholepis (Mont. & Bosch) Elix & Hale are excluded from the lichen of Korea. In addition, a key for the species of the Korean Myelochroa is provided.

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 of eight species of Usnea, including one new record, Usnea hakonensis Asahina, are documented. Detailed 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.

Parmotrema clavuliferum ($R{\ddot{a}}s{\ddot{a}}nen$) Streimann and P. reticulatum (Taylor) M. Choisy (Parmeliaceae, lichenized Ascomycotina) have similar morphological characters such as wide lobes with soralia, reticulate-maculate on upper surface of lobes, and marginal cilia. In addition, they both produce salazinic acid and atranorin as major chemical substances. These similar properties found in both species have led to confusion in recognizing them as distinct species; however, P. clavuliferum is distinguished from the latter by capitate soralia on short laciniae which are always mottled white and by the production of fatty acid and gyrophoric acid together with salazinic acid. In addition, the most likely phylogenetic tree of these species shows that they are nested in well-supported monophyletic groups. Therefore, it is reasonable to recognize them as two separate species, P. clavuliferum and P. reticulatum.

This study reports, for the first time, the ivestigation of the distribution of Korean saxicolous lichens in the coastal rocks of U-do islet, which is known as an unpolluted zone in Jeju. More than thirty lichens were obtained and investigated from the coastal rocks frequently contacted by seawater. A molecular analysis using PCR amplification of the rRNA ITS regions revealed the coastal rock lichens could be placed into 8 families and 14 genera, Ramalinaceae (Bacidia, Ramalina), Physciaceae (Buellia, Dirinaria, Phaeophyscia, Physcia, Pyxine), Lecanoraceae (Candelaria, Lecanora), Parmeliaceae (Xan­thopannelia), Graphidaceae (Graphis), Pertusariaceae (Pertusaria), Rhizocarpaceae (Rhizocarpon), and Teloschistaceae (Caloplaca), showing a diversity of lichens, with foliose (flat leaf-like), crustose (crust­like), and fruticose (miniature shrub-like) life forms might be distributed in the coastal rocks. These findings suggested the possibility that the lichens identified in the present work might be resistant to a salty environment.
