  • A single postlarva (9.72 mm in standard length) specimen of Crossorhombus azureus (Alcock, 1889) belonging to the family Bothidae, was collected using a bongo net from the southern sea of Korea on December 10, 2019. This species is characterized by having spines on post basipterygial processes. It has two eyes located at the opposite side in head, which accordingly belongs to pre-metamorphosis stage. Melanophores are distributed on the dorsal and anal fin base on the right side (blind side), which is regarded as a useful identification key distinguishing C. azureus from congeneric species in their postlarval stage. A molecular analysis based on mitochondrial DNA COI sequences showed that our specimen was closely matched to adult C. azureus (K2P distance = 0.017). As there is no Korean name for the genus Crossorhombus in spite of presence of Crossorhombus kobensis and its Korean name "Go-be-dung-geul-neob-chi" in Korea, we proposed a new Korean name "Dung-geul-neob-chi-sog" for the genus Crossorhombus and "Pa-lang-dung-geul-neob-chi" for the species C. azureus.

  • Eighteen specimens of juvenile Mugilidae were collected in October 2012 from the southern coastal waters of Jeju Island, and identified based on analysis of their mitochondrial DNA16S rRNA sequences. Seventeen specimens of Oedalechilus labiosus and a single specimen of Ellochelon vaigiensis were found, constituting a new record for these species among Korean ichthyofauna. O. labiosus is identified by the angle at the posterior end of its mouth, which contains a round notch, a darkish dorsal margin of the pectoral fin, the presence of 33-36 lateral line scales, and 23-24 vertebrae. E. vaigiensis is identified by dark dorsal and pectoral fins, the presence of 26 lateral line scales, and 25 vertebrae. The proposed Korean name for Oedalechilus is 'Sol-ip-sung-eo-sok' and that for Ellochelon is 'Nup-jeok-ggo-ri-sung-eo-sok'. The proposed Korean names for the species are 'Sol-ip-sung-eo' and 'Nup-jeok-ggo-ri-sung-eo' for O. labiosus and E. vaigiensis, respectively. We present a key for identification of the Mugilidae family of species from Korea, and include these two newly recorded species.

  • 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.

  • A newly recorded species, Fimbristylis hookeriana Boeckeler, was found in Gyema-ri, Hongnongeup, Yeonggwang-gun, Jeollanam-do and Munyeo-do Is., Gunsan-si, Jeollabuk-do, Korea. Fimbristylis hookeriana is closely related to F. dichotoma, which has ovoid spikelets, deciduous scales, pubescent culms, and short style. However, this species is distinguished by very narrowly ovoid spikelets, persistent scales, glabrous culms, and long style. We propose a new Korean name, 'Ba-Wi-Ha-Neul-Ji-Gi', meaning that this inhabits on dried rocks near seashore. Redescription, illustrations, photographs, table, and a key to species of the Fimbristylis Vahl in Korea are provided.

  • A fungal isolate belonging to the phylum Ascomycota was isolated and identified as Talaromyces veerkampii in 2017 during a survey of fungal diversity in field soils in Korea. This fungal isolate was identified and described based on macro- and micromorphological and molecular characterization. The identification was also based on partial 18S-ITS1-5.8S-ITS2-28S rDNA and calmodulin (CaM)-encoding gene sequencing data. Talaromyces veerkampii has not been previously reported in Korea. Thus, we report here a newly discovered species from soil in Korea along with its morphological and molecular characteristics.

  • This study aimed to elucidate the distribution of vascular plants on the Deok mountain in Ganghwa-gun, Korea. The results of 10 field surveys from March to October of 2019 identified 532 taxa in total, representing 482 species, 9 subspecies, 39 varieties, 1 form, and 1 hybrid in 318 genera and 105 families. The plant formation of Deok mountain is the deciduous broad-leaved and conifer mixed forest, which is the common one in the middle region of the Korean Peninsula. Among them, 301 taxa were newly recorded in this study, 7 taxa were endemic plants to Korea, 3 taxa were red list plants. The floristic target plants amounted to 41 taxa, specifically 1 taxon of grade V, 2 taxa of grade IV, 7 taxa of grade III, 9 taxa of grade II, and 22 taxa of grade I. Alien plants were recorded a total of 73 taxa with a naturalized index of 13.7%, the urbanization index was calculated to be 11.8% and 4 taxa were ecosystem disturbance plants.

  • Oak tree death caused by symbiosis of an ambrosia beetle, Platypus koryoensis, and an ophiostomatoid filamentous fungus, Raffaelea quercus-mongolicae, has been a nationwide problem in Korea since 2004. In this study, we surveyed the yeast species associated with P. koryoensis to better understand the diversity of fungal associates of the beetle pest. In 2009, a total of 195 yeast isolates were sampled from larvae and adult beetles (female and male) of P. koryoensis in Cheonan, Goyang, and Paju; 8 species were identified by based on their morphological, biochemical and molecular analyses. Meyerozyma guilliermondii and Candida kashinagacola were found to be the two dominant species. Among the 8 species, Candida homilentoma was a newly recorded yeast species in Korea, and thus, its mycological characteristics were described. The P. koryoensis symbiont R. quercusmongolicae did not show extracelluar CM-cellulase, xylanase and avicelase activity that are responsible for degradation of wood structure; however, C. kashinagacola and M. guilliermondii did show the three extracellular enzymatic activities. Extracelluar CM-cellulase activity was also found in Ambrosiozyma sp., C. homilentoma, C. kashinagacola, and Candida sp. Extracelluar pectinase activity was detected in Ambrosiozyma sp., C. homilentoma, Candida sp., and M. guilliermondii. All the 8 yeast species displayed compatible relationships with R. quercus-mongolicae when they were co-cultivated on yeast extract-malt extract plates. Overall, our results demonstrated that P. koryoensis carries the yeast species as a symbiotic fungal associate. This is first report of yeast diversity associated with P. koryoensis.

  • The hypotrichous ciliates (Protozoa , Ciliophora, Hypotrichida) inhabiting the Han River in Seoul were systematically investigated. Several Collections were made from 6 November 1986 to 8 November 1987 at 9 sites located in the Han River. Collected protozoans were cultured and characterized cyto-morphologically under the living and/or stained conditions, As a result, 7 species of hypotrichs in 4 families were identified of which 3 species are newly recorded from Korea ; Paraurostyla weissei (Stein, 1859_, Aspidisca cicada(O.F. Mller, 1786) and Euplotes patella (O.f.Mller, 1773). The identified species were redescribed with illustrations and photographs. The morphological similarities among them were numerically analyzed by UPGMA method, and its result of clustering concurs in general with the orthodox classification scheme.
