  • Korea has a long history from several thousand years ago. Specially stonecultural properties were used for the long period in Korea. Ancient tombs of prehistoric age, Sukgul-am (stone cave), Chumsung-dae (astronomical observatory)and stone statue of Buddha in the period of three dynasties were made of stone. There after the foundation stone, mortarstone, millstone, and other stone facilities at home have been also used for a long time. For the conservation of the cultural properties, the ecological distribution of lichens was investigated with the stone buildings around tombs and multistory stonepagodas.1. Yoo-nung (The tomb of Emperor Sungjong) : The stone buildings of granitearound tomb about 80 years old are clean and solid in quality, but they were covered in places with three kinds of lichens as the circle forms of pale-green and dark-gray colored thallus in crustose type. They were examined ecological distribution, identification and measurement of lobe size of lichens.2. Yoong-nung (The tomb of son of Emperor Yung-jong) : Granite buildings around tomb about 200 years old are also clean, moreover, they were also covered with the same kinds of crustose lichens in overlap.3. Yung-nung (The tomb of Emperor Sejong) : More than seven species of crustose, foliose and one species of fruticose lichens were growing on thegranite stone buildings built in about 500 years ago.4. Shilluk-sa multistory brick pagoda : It was built at the Koryo dynasty more than about 700 years. More than 5 species of crustose folios and two species of fruticose lichens were growing well on the granite stone at shade area. It was assumed that foliose lichens as dominant species with the respect of ecological aspect.5. Shilluk-sa multistory marble pagoda : This marble pagoda was built at the middle period of the Koryo dynasty as the same age of multistory brick pagoda. It was covered with black colored thallus such as crustose lichens. It is seemed that only crustose lichens on the stone were due to the drymarble stone. From the results described above, distribution of lichens showed that only crustose lichens on the stone from the short history (about 100-200 years) were grown with small size of circle form, stone buildings over 500 years were covered with crustose, folios and fruticose lichens, and the lichens distribution on the stonemore than 500 years appeared more foliose and fruticose than crustose type. Therefore, it is suggested that the succession of lichens on the stone buildings iscrustose$\rightarrow$foliose$\rightarrow$fruticose.Parmelia mexicana, Cladonia floerkeana, Ramalina yasudae identified are described in this paper and other unidentified species of saxicolous lichens will bedescribed later.

  • The genus Candelaria is characterized by a micro-foliose to micro-fruticose thallus and contains eight species, two of which were reported in South Korea. During the excursion of a Korean lichen flora investigation, some suspected Candelaria concolor specimens were collected, and their morphological, chemical, molecular phylogenetic, and geographic analyses were conducted. The samples eventually proved to be a new species, Candelaria asiatica, which can be recognized by a small, yellow lobate thallus with a pulverulent surface, and a fragile lobe margin with blastidia or phyllidia-like lobules.

  • Lithothamnion muelleri is reported for the first time as one of the main components of rhodolith beds along the Eastern Pacific Ocean based on samples from Washington State (USA), Pacific Baja California (M$\acute{e}$xico), southern Nicaragua, and Costa Rica. Individual rhodoliths ranged from fruticose to lumpy in morphology, and bi-sporangial, tetrasporangial, and gametangial plants were similar to those described from Australia and Brazil. Our study revealed a surprisingly wide latitudinal distribution of this species along the American continent. Its documentation in the Eastern Pacific will facilitate a more accurate interpretation of the ecology, biology, and biogeography of rhodolith beds worldwide.

  • The morphology, anatomy and reproduction (tetra/bisporic and male) of Lithothamnion japonicum Foslie was studied, using holotype material and materials collected from Korea. Lithothamnion japonicum is characterized based on the presence of encrusting, warty to fruticose thallus, branched or unbranched short and cylindrical protuberances, conical shaped spermatangial conceptacles, branched (dendroid) spermatangial systems formed on floor, walls, and roof of conceptacle chamber, cylindrical shaped spermatangial conceptacle canal, 9-10 cell layered spermatangial conceptacle roof, raised tetra/bisporangial conceptacles without rims, flattened tetra/bisporangial conceptacle pore plate, 16-50 pores on each pore plate, 6-8 rosette cells surrounded by each pore, pore canal lining filaments composed of tetra/bisporangial conceptacle roof, and buried senescent tetra/bisporangial conceptacles completely infilled with relatively large and irregularly arranged calcified sterile cells. In this study, we report a new record of Lithothamnion japonicum from Korean coasts.

  • Background: In this article, it was analyzed how snow melting affects the assembly of lichen and moss communities in a small area of the coastal region of Barton Peninsula, which is in maritime Antarctic. In the small area, even though there is a huge gap of difference of the environment between the snow-filled area and snow-melt one, the latter did not have distinctive environmental gradients. Results: Depending on the snow melting time, coverage and species diversity of lichens and mosses tend to increase remarkably. For species with significant changes depending on the snow-covered period, there are Andreaea regularis, crustose lichens, Placopsis contortuplicata, Usnea aurantiaco-atra, and snow algae. In this area, the process of vegetation assembly process has shown the directional development in the order of snow algae${\rightarrow}$crustose, lichen sub-formation${\rightarrow}$fruticose lichen, moss cushion sub-formation (Andreaea sociation)${\rightarrow}$fruticose lichen, and moss cushion sub-formation (Usnea sociation), according to the order of snow melting. These directional development stages are shown in gradual change in small area with the snow melting phenomena. However, in the snow-free area, where water is sufficiently supplied, it is expected that moss carpet sub-formation (Sanionia sociation) will be developed. Vegetation development in the small area with the snow melting phenomena, depending on differences of resistance on snow kill and moisture settled by species in according to the time of snow melting, tolerance model to form community is followed. Conclusions: The research results explain the development of vegetation in the Antarctic tundra and its spatial distribution according to the period for growth of lichens and mosses in the summer time by differences of snow melting in the small area. In the future, if research for the community development process in a large scale will be done, it will be helpful to figure out temporal and spatial dynamic of vegetation in the Antarctic tundra where snow and glaciers melt rapidly due to climatic warming.

  • A lichen is a complex microorganism comprising fungi and algae. Various lichens are commonly found in cultural heritage and are reportedly related to weathering. Lichens are commonly studied in Europe; however, few reports exist on lichens in Korean cultural heritage. The present study was conducted as part of the Korean National Arboretum's "A study on the Fungus and Lichen." We report the lichen diversity found at the Placenta Chambers of King Sejong's Sons, Seongju. A total of 65 lichens were collected from 19 placenta chambers and one memorial stone. We identified 40 species belonging to 10 genera, 17 families, and 23 orders. Morphological identification revealed that foliose lichens in the form of leaves(24, 36.9%) and crustose lichens in the form of crust(24, 36.9%) were distributed at a higher percentage than that of fruticose lichen in the form of branches(17, 26.2%). Xanthoparmelia coreana(foliose lichen) and Lepraria sp.(crustose lichen) were the most collected lichens and were distributed on 19 chambers. In addition, Clodonia, a fruticose lichen, had the highest species diversity with eight species. The highest species diversity of lichens was identified on the chamber of Prince Kyeyang(16 lichens), whereas the chamber of Prince Geumsung had the lowest species diversity(five lichens). This study will be used as primary data for the study of distribution of lichen diversity in Korean cultural heritage.

  • This study was initially performed to obtain fundamental data on lichen distribution depending on environmental condiLichens distributed on coastal rocks atleast 20 m far away from the coast were also investigated. Analyof morphological characteristics and rDNA ITS clones revealed that lichens containing 9 families and 15 genera were distributed in coastal rocks of V-do, while lichens containing 10 families and 14 genera were in field rocks, demonstrating little difference of diversity between both sites. Foliose lichens such as PhaeophysPhyscia, Pyxine belonging to the family Physciaceae were representatives distributed in coastal rocks of V-do, along with Xanthoparmelia belonging to Parmeliaceae, fruticose lichens such as Ramalina to Ramaliand crustose lichen Lecanora to Lecanoraceae. In contrast, foliose lichen Cladonia belonging to the family Cladoniaceae, fruitcose lichen Stereocaulon to Streocaulaceae, and crustose lichen Porpidia to Porpidwere found only on the surface of field rocks. Crustose lichens containing genera Caloplaca, CanDirinaria, Graphis, Rhizocarpon, and Pertusaria were rarely distributed in coastal rocks, and most of them were also found in field rocks.

  • 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.
