In May 2020, a single larval specimen (5.14 mm in total length) was collected from the southeastern sea of Jeju Island of Korea using bongo net. The specimen was identified as Lepidotrigla longifaciata based on mitochondrial DNA cytochrome c oxidase subunit I sequences. The morphological traits of the L. longifaciata larva are as follows: a long snout, a large mouth, large fan-shaped pectoral fins, and black melanophores scattered on the abdominal cavity and nape. We propose the new Korean name 'Gin-meo-ri-dal-jae' for this species, which was first discovered in Korea.

During an investigation of fungi of the order Mucorales from freshwater and sediment samples in Korea, we isolated six strains, NNIBRFG6649, NNIBRFG6255, NNIBRFG1498, CNUFC-YJ13, CNUFC-YR7, and NNIBRFG2739. The morphology and phylogeny of these strains were analyzed. Based on the morphological characteristics and molecular data from internal transcribed spacer (ITS) region, the isolates NNIBRFG6649 and NNIBRFG6255 were identified as Mucor abundans, and M. aligarensis, respectively. The isolates NNIBRFG1498 and CNUFC-YJ13 were identified as M. moelleri, whereas the isolates CNUFC-YR7 and NNIBRFG2739 were identified as M. heterogamus. To the best of our knowledge, M. abundans, M. aligarensis, M. moelleri, and M. heterogamus have not yet been reported in Korea.

Macrofungi play important roles in forest ecology as wood decayers, symbionts, and pathogens of living trees. For the effective forest management, it is imperative to have a comprehensive overview of macrofungi diversity in specific areas. As a part of the National Institute of Biological Resources projects for discovering indigenous fungi in Korea, we collected macrofungi in Gayasan National Park from 2017 to 2018. These specimens were identified based on morphological characteristics and sequence analysis of internal transcribed spacer (ITS) or the nuclear large subunit rRNA (LSU) region. We discovered 17 macrofungi new to Korea: Butyrea japonica, Ceriporia nanlingensis, Coltricia weii, Coltriciella subglobosa, Crepidotus crocophyllus, Cylindrobasidium laeve, Fulvoderma scaurum, Laetiporus cremeiporus, Lentinellus castoreus, Leucogyrophana mollusca, Marasmius insolitus, Nidularia deformis, Phaeophlebiopsis peniophoroides, Phanerochaete angustocystidiata, Phlebiopsis pilatii, Postia coeruleivirens, and Tengioboletus fujianensis. We described their detailed morphological characteristics.

Plagiothecium platyphyllum Mönk (Plagiotheciaceae), a species unrecorded previously in the moss flora of the Republic of Korea (South Korea), was collected in the Surak stream of Mt. Daedun in Jeollabuk-do Wanju-gun Sanbuk-ri. This species was known to be distributed around China, Japan, North Korea, and Europe. The morphological characters of P. platyphyllum's leaf are ovate-lanceolate, and mostly asymmetric, 2.0~2.5 × 1.0~1.4 mm. The margin of the leaf is entirely below and weakly serrulated near the apex. The costae parts are double, unequal, with one branch reaching to the mid-leaf. Median leaf cells are linear-rhomboidal, 80~127 × 10~16 ㎛ and alar cells are rectangular. Central strand is developed in the core of the stem.

Since a new (unrecorded) species was reported in 2016, a total of four sea snake species are currently listed in Korean waters. Although the possibility of year-round inhabitation of sea snakes in Korean waters has increased due to climate change, the related studies are scarce because of the lack of human resources and available equipment. We placed posters and banners requesting voluntary information on sea snakes in coastal regions and Jeju Island to obtain information on sea snake distributions in the coasts of South Korea and possible specimens through volunteer activities. As a result, we received total 45 reliable reports, including photographs or video, between March 2013 and December 2016. Eighteen reports on three sea snake species and thirteen capture cases of two species were submitted from Jeju Island and southern coastal regions of Korea mostly between August and November. There were twenty-seven false reports including seven cases of terrestrial snakes, eighteen fishes, and one each of invertebrate and inanimate material. Based on the results, we proposed the effective way of sea snake surveys using volunteers.

Since the establishment of the Korean Society of Plant Taxonomists (KSPT) on Dec. 13, 1968, the professional manpower training and research activities have been analyzed. The survey method was based on the homepage of the KSPT and the Korean J. Pl. Taxon, and on data provided by each university about professional manpower. Over the past 50 years, a total of 680 specialists in plant taxonomy have been trained, consisting of 537 master's degree holders (274 males, 263 females) from 30 universities and 143 PhDs (97 males, 46 females) from 26 universities, and the number has increased significantly since 1998. With regard to changes in the field of research over the last ten years, revision papers were the most common in the period of 1988-1997 (72%), but this rate has decreased to 51% over the last ten years, while the number of unrecorded papers has increased to 28%. In the 629 revision papers on taxa, 49% of the taxa belong to Asteraceae, Ranunculaceae, Cyperaceae, Liliaceae, Rosaceae, Fabaceae, Apiaceae, Lamiaceae, Orchidaceae, Oleaceae, Euphorbiaceae, Polygonaceae, and Amaryllidaceae. With regard to changes in research methods, the number of morphological papers increased from 6% to 51%, while pollen papers have decreased from a rate of 20% to only 2%. Chromosome studies account for 3-4%, chemotaxonomic studies 2%, and DNA studies remain low at 3-16%. The percentage of papers in English now stands at 43%, mainly due to the increased number of papers on unrecorded species.

Two unrecorded naturalized species, Stachys agraria Schltdl. & Cham. and Dracocephalum moldavica L (Lamiaceae), are newly reported in Korea. Stachys agraria and D. moldavica were found at Seogwipo-si on Jeju-do and at ChunChen-si in Gangwondo in Korea, respectively. Stachys agraria is distinguished from other related Korean taxa by corolla of 2.4-5.2 mm long with six to twelve flowers in the node. Its local name is "Ae-gi-seok-jam-pul" based on shorter than longer corollar. Dracocephalum moldavica was distinguishable from other Dracocephalum in Korea by the following combination of characters, oblong to ovate-triangular ($1.7-2.4cm{\times}0.8-1.2cm$) leaves and rough crenate at the margin. This taxon is referred to as 'Hyang-yong-meo-ri' in Korean based on its fragrance. We provide a description, illustrations, photographs, and a key of related taxa in Korea.

Larvae of fishes were collected at 26 stations in the Korea Strait, by horizontal towings using the fish larval net (Norpac) in the surface layer and by oblique towings using Isaac-Kid mid-water trawl in the mid-water layer in summer (July) and in autumn (November), in 1983. The towing speed was 1.5 knots. Of the larval fish examined, 3,529 individuals were identified to generic and specific levels. They belong to 27 families, consisting of 38 species in 37 genera. Unidentified were 114 specimens. The most abundant species was Engraulis japonica which occupied $88.5\%$ of the whole 3,645 individuals. Diaphus sp. took the second place with 50 individuals ($l.3\%$). Seasonally abundant species were in the order of Engraulis japonica, a Gobid, Trichiurus lepturus, and Diaphus sp. in summer, and in the order of Diaphus sp., Engraxlis japonica, Bothus sp., and a Ophichthid in autumn. Of these larvae, Engraulis japonica and Diaphus sp. continuously appeared from summer to Autumn. Champsodon sp., Diaphus sp. and Synagrops philippinensis were unrecorded species in Korea.

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. Furthermore, The habitat of 5 taxa such as Asplenium trichomanes L., Asplenium wilfordii Mett. ex Kuhn, Miscanthus sinensis var. chejuensis Y.N.Lee, Impatiens kojeensisi Y.N.Lee and Digitaria violascens var. intersita Ohwi were newly added to the flora of korea, and 29 taxa of induced and naturalized plants were observed in this area.
