  • 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.

  • $Lobaria$ (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.

  • 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.

  • 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.

  • After an overview on the temporary situation of the lichenology in South Korea, localities of 95 mac-rolichen taxa are reported for South Korea. In this revised lichen flora of South Korea, 16 species are apparently new to the territory. Voucher specimens have been deposited in the Korean Lichen Research Institute (KoLRI) at Sunchon National University in Korea, and duplicates have also been donated to the National History Museum and Institute, in Chiba, (CBM) Japan.

  • Cladonia peziziformis (With.) J.R. Laundon was collected from Baega mountain, Jeonnam Province, Korea in 2008. It is characterized by short and slender podetia with verruculose surface, split along the sides. Apothecia large, pale brown, always growing on the top of the podetia. Primary squamules shell-like, thick, and convex. Fumarprotocetraric acid contained in thallus. This is the first record of this species in Korea.

  • Heterodermia squamulosa (Degel.) W.L. Culb. was found in the mountain of Gariwang, Gangwon province, in 2008. It is characterized by numerous squamules along the margin, decorticate and white lower surface, rhizines along the margin, black and densely squarrosely branched, usually forming a dense mat under the thallus. Apothecia margins densely squamulose, ascospores $12\sim15\times25\sim30{\mu}m$. Atranorin and zeorin contained in thallus. This is the first record of this species in South Korea.

  • 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 (M$\ddot{u}$ll. 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 M$\ddot{u}$ll. 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.

  • 지의류는 효모를 포함하는 곰팡이와 조류의 공생체로 복합미생물이다. 지의류의 다양한 종들은 문화재에서 흔히 발견되며 풍화작용과도 관련되어 있는 것으로 보고되어 유럽에서는 많은 연구가 이루어져 왔다. 그러나 우리나라의 문화재에서 지의류에 관한 연구 보고는 거의 이루어지고 있지 않다. 본 연구는 국립수목원에서 진행하는 생활권 및 특수지역에 서식하는 버섯·지의류 탐색 및 분류 연구 조사의 일환으로 수행되었으며 성주 세종대왕자 태실의 지의류상 조사에서 밝혀진 내용을 보고한다. 총 19기의 태실로부터 총 65점의 지의류를 채집하였으며, 채집된 지의류를 형태학 및 분자생물학적으로 동정한 결과 3강 10목 17과 23속 40종이 밝혀졌다. 형태학적 분류 결과 잎의 형태를 띠는 엽상지의류(24점, 36.9%)와 딱지 형태를 띠는 가상지의류(24점, 36.9%)가 나뭇가지 형태를 띠는 수지상지의류(17점, 26.2%)에 비해 높은 비율로 분포하였다. 이들 중 엽상지의류에 속하는 Xanthoparmelia coreana가 가장 많이 채집되었으며, 가상지의류인 Lepraria sp.가 19기 태실 모두에 분포하였다. 또한 수지상 지의류인 Cladonia속이 8종으로 종 다양성이 가장 높았다. 계양군 태실에서 16종의 지의류가 채집되어 가장 높은 종 다양성을 보인 반면, 금성대군 태실의 경우 5종의 지의류가 채집되어 가장 낮은 종 다양성을 보였다. 본 연구는 우리나라 문화재에 분포하는 지의류 종 다양성 연구에 기초자료로 활용될 것이다.

  • Lichen communities at the Duckyoo National Park were studied by the analysis of concentration. Thirty three species of lichen identified were divided into three vegetational groups and fourty two stands into three environmental groups by sum of square algorithm. The sharpness of the nine blocks table is low, that is C=0.05, which means the divergency of lichen communities to be high. The result reveals that canonical first variate is 0.313 (91%) and second variate 0.100 (9%), and calculates the expected deviation from the first variate. The intermediate zone of environmental group is more important area to distribute lichen species than other zone. The computer program for this study was made by APPLE SOFT BASIC (DOS 3.3).
