  • The vascular flora of Dalmasan and its adjacent regions, located in Haenam-gun, Jellanam-do, is surveyed from Mar. to Oct. 2005. The number of the vascular plant taxa based on voucher specimens is 545 total which belongs to 112 families, 322 genera, 473 species, 3 subspecies, 60 varieties and 9 forms respectively. Among them, 12 taxa of Korean endemics and 4 taxa of rare and endangered plants were investigated in addition to 86 taxa of specially designated plants announced by the Ministry of Environment. A unrecorded taxon, Stellaria neglecta Weihe, is also collected in this area.

  • Two unrecorded fungi, Diaporthe perseae and Fusarium falciforme, were isolated from soil sampled from Dokdo in Korea. There have been many reports of Diaporthe sp. and Fusarium sp. in mainland Korea but none of them have reported in Dokdo so far. We used the morphological features and two molecular markers including the internal transcribed spacer and translation elongation factor 1-α region to compare and analyze these species with the closely related taxa. As a result, we confirmed that these fungi were unrecorded soil fungi in Korea. Then, the cultural and morphological characteristics such as the conidia of these two fungal species could be clarified. These results are expected to help us to understand the distribution of fungi in Dokdo and manage the Dokdo Island Natural Reserve.

  • Saussurea nipponica subsp. higomontana was recorded first from Mt. Mudeung-san, Gwangju-si, Korea. We named the plant Mu-deung-chui. It had been considered as an endemic plant to Japan. S. nipponica sensu lato is the one of the most famous polymorphic species which consists of 7 infraspecific taxa (subspecies) isolating geographically. Among them, S. nipponica subsp. higomontana is distributed on high mountain regions of Kyushu and Shikoku.

  • An unrecorded species of Oldenlandia brachypoda DC. is newly reported from Seogwipo-si, Jejudo, This species is distinguished from Oldenlandia diffusa, the related taxa by the surface and length of the pedicel, the number of flowerd, the shape of the calyx and capsule. The new Korean name 'je-ju-baeg-un-pul', was given considering the collect locality. The illustration, description and key of characters are provided.

  • Through ten field surveys in Kanghwa Island from August of 1997 to March of 2002, total 107 specimens of wood-rotting fungi belonging to the Aphyllophorales were collected and identified to the species. They taxonomically amounted to 10 families, 31 genera, and 48 species. Among them, one family, Steccherinaceae, and four genera, Australohydnum, Castanoporus, Dacryobolus and Haplotrichum were confirmed as new to Korea. Five unrecorded species, Australohydnum dregeanum, Castanoporus castaneus, Dacryobolus karstenii, Haplotrichum conspersum and Hyphoderma odontiiforme were registered here with descriptions.

  • Higher Fungi were collected. twice a month from May to September 2004 during field survey trips to Seoraksan and Odaesan National Parks. All the collected specimens were investigated for the morphological characters of carpophores and other features, and deposited in the herbarium of the Entomopathogenic Fungal Culture Collection (EFCC), Kangwon National University, Chuncheon. Among the identified specimens, three genera Rhodotus, Hotermannia and Sebacina and four species Rhodotus palmatus, Gomphus clavatus, Holtermannia corniformis and Sebacina incrustans were confirmed as new to Korea and reported here with descriptions.

  • Freshwater is a diverse and complex environment for fungi and provides several types of habitat including plant litter, sediment, and carcasses. We collected plant litter from the main stream and branch streams of Nakdong River, Sohancheon in Samcheok, and Geumoreum in Jeju. From several samples of plant litter, we isolated 8 fungal strains belonging to 4 Montagnulaceae species unrecorded in Korea: Paraconiothyrium archidendri, Paraphaeosphaeria sporulosa, Paraphaeosphaeria michotii, and Paraphaeosphaeria viridescens. These fungi were identified by phylogenetic analysis using the internal transcribed spacer (ITS) region and examination of morphological characteristics. Montagnulaceae is known as one of the families in Pleosporales and includes coniothyrium-like fungi. In this study, we described phylogenetic analysis and mycological characteristics of these species, and this is the first report of these taxa in Korea.

  • Cynanchum L. in the subfamily Asclepiadoideae (Apocynaceae) includes four recognized species on the Korean peninsula, two of which are native to South Korea. However, the species ranges in South Korea are poorly defined. During a field survey, we discovered C. thesioides, previously unrecorded in South Korea, in Gimpo-si, Gyeonggi-do, and found an additional population of C. chinense, for which only one population has been reported in South Korea. The two taxa are considered rare species with extremely restricted distributions in South Korea, especially C. thesioides. We provide fundamental information, including descriptions, images of the habitats and morphological characters, and a taxonomic key for identification and assessments of the conservation status of Cynanchum species in Korea.

  • This is a report of an unrecorded species of Hedyotis from Korea, Hedyotis chrysotricha (Palib.) Merr., found in Yeongam-gun, Jeollanam-do. The species can be distinguished from other Hedyotis species by trichomes that cover the entire plant, ovate leaves, mauve or white corolla, and the corolla lobe of which the length measures more than twice its width. The species was named after its findspot and is hence called 'Yeongam-pul.' An illustration, description and key to the taxa related to Hedyotis are provided.
