한국산 갯보리속은 개밀속과 혼돈하여 사용하여 온 바, 형태적으로 갯보리속의 범주 및 특성을 재검토하였고, 이때까지 한반도 식물상에 기록된 바 없는 갯보리속의 2개 미기록 분류군, 둔치개밀과 여름개밀을 각각 전라남도와 전라북도에서 채집된 표본을 근거로 보고하였다. 둔치개밀은 강가 주변의 생육지, 항상 곧추서는 꽃차례, 화서에 밀착된 소수, 지상부 아래쪽 마디에서 새로운 개체를 무성적으로 증식하는 점에서 다른 분류군과 구별되고, 여름개밀은 개밀과 비슷하지만 개화시기가 여름철이고, 옆으로 약간 휘는 꽃차례, 포령의 맥수, 화서에 밀착된 소수와 같은 특징에 의해 구별되었다. 한국산 두 미기록 분류군에 대한 기재, 사진 및 근연 분류군간의 검색표를 제시하였다.

As a subset study to discover indigenous prokaryotic species in Korea in 2014, a total of 34 bacterial strains assigned to the phylum Actinobacteria were isolated from various environmental samples collected from activate sludge, biotite, freshwater, gut of marine organisms, mud flat, sediment, soil, spent mushroom compost and sea water. On the basis of high 16S rRNA gene sequence similarity and a tight phylogenetic association with the closest species, it was revealed that each strain was assigned to independent and previously described bacterial species, with the exception of one isolate. There is no official report that these 34 species included in the phylum Actinobacteria have been described in Korea: 6 species of 5 genera in the order Corynebacteriales, 1 species of 1 genus in the order Frankiales, 2 species of 2 genera in the Micromonosporales, 14 species of 10 genera in Micrococcales, 2 species of 2 genera in the Propionibacteriales, 1 species of 1 genus in the Pseudonocardiales, 4 species of 2 genera in the Streptomycetales, 2 species of 2 genera in the Streptosporangiales and 1 species of 1 genus in the Solirubrobacterales. Gram reaction, cell and colony morphology, pigmentation, physiological characteristics, isolation sources and strain IDs are described in the section of species description.

한국의 조개나물속은 주로 해발 50-1000 m의 낮은 산지 또는 저지대에 분포하며 5분류군이 알려져 있다. 한국산 조개나물속의 미기록 식물로 Ajuga nipponensis Makino를 보고한다. 본 분류군은 충청남도 보령시 녹도의 마을 주변 길가에서 확인하였다. A. nipponensis는 직립하거나 기며, 줄기는 뿌리부터 여러 갈래로 나뉘며, 화통은 길이 10-12 mm, 연한 흰분홍색으로 한국산 조개나물속 다른 분류군들과 구분이 된다. 국명은 화통의 색깔을 고려하여, '분홍꽃조개나물'로 신칭하였다. 한국산 조개나물속 분류군에 대한 검색표를 제시하였다.

The goal of this study was to isolate and identify wild yeasts from soil samples. The 15 wild yeast strains were isolated from the soil samples collected in Pocheon city, Gyeonggi Province, Korea. Among them, four yeast stains were unrecorded, and 11 yeast stains were previously recorded in Korea. To identify wild yeasts, microbiological characteristics were observed by API 20C AUX kit. Pairwise sequence comparisons of the D1/D2 domain of the 26S rRNA were performed using Basic Local Alignment Search Tool(BLAST). Cell morphology of yeast strains was examined by phase contrast microscope. All strains were oval-shaped and polar budding and positive for assimilation of glucose, 2-keto-ᴅ-gluconate, N-acetyl-ᴅ-glucosamine, ᴅ-maltose and ᴅ-saccharose (sucrose). There is no official report that describes these four yeast species: one strain of the genus Kodamaea in the family Metschnikowiaceae and three strains of the Hannaella in the family Bulleribasidiaceae. Kodamaea ohmeri YI7, Hannaella kunmingensis YP355, Hannaella luteola YP230 and Hannaella oryzae YP366 were recorded in Korea, for the first time.

제주도의 서귀포시 상효동과 제주시 오등동의 계곡 주변에서 발견한 쐐기풀과의 몽울풀속에 속하는 미기록 식물, 푸른몽울풀(Elatostema laetevirens Makino)을 채집하여 기재하였다. 푸른몽울풀은 다년초이고 줄기에 개출모가 없는 점과 화서의 자루가 발달하지 않는 특징으로 국내 몽울풀속의 다른 종들과 쉽게 구분이 된다. 잎 표면에 광택이 없으며, 표면의 색이 청록색인 특징을 고려하여 '푸른몽울풀'로 명명하였다.

In 2022, during a survey of intertidal fauna around Jindo located in the Dadohaehaesang National Park in the South Sea, epizoic hydroids attaching onto seagrass (Zostera sp.) growing on soft sediments were collected. Through taxonomic examination, an unrecorded species, Ectopleura radiata, is newly added to the hydrozoan fauna of Korea. In addition, DNA barcoding for species from Ectopleura and Tubularia clarified the distinction among morphologically indistinguishable species without gonophores. Up to now, only one species, E. crocea, has been reported in Korea. Through this study, a total of two species belonging to genus Ectopleura have been reported in Korean waters so far.

Larvae of shoot flies are known to live on decaying plants or to infest the stems of wild and crop plants. Among them, some species are economically very important pests that damage fruits or cereal crops in Old world tropics and subtropics. In Korea, three species, Atherigona orientalis, A. oryzae, and A. soccata, are managed as quarantine pests. To date, a total of five species, A. (Acritochaeta) orientalis Schiner, A. (Atherigona) bifurca Suh and Kwon, A. (A.) biseta Karl, A. (A.) falcata (Thomson) and A. (A.) oryzae Malloch, including two quarantine pests, have been recorded in Korean fauna. During the survey of Korean houseflies, the authors discovered two new unrecorded species, A. (A.) miliaceae Malloch and A. (A.) reversura Villeneuve. The diagnoses and illustrations of these species are provided in addition to the key to the Korean Atherigona species.

Diatoms are unicellular eukaryotic microalgae, and they are highly diversified in aquatic environments. We describe an unrecorded diatom species Fragilaria saxoplanctonica Lange-Bertalot & Ulrich (Bacillariophyceae) collected from Paldang Reservoir, Korea, on 4 April 2022. The valve was needle shaped and narrowly rectangular, its ends were rounded, and no spines were found on the outline of their valves. The valve was 67.2-70.2㎛ in length and 1.4-2.9㎛ in width. The ratio of width-to-length was 1 : 23.2-50.1. The pattern of striation was alternate or opposite, and the number of striae in 10㎛ was 24-26. Molecular comparisons of the 18S rDNA and rbcL sequences showed that it belonged to the genus Fragilaria. These morphological and phylogenetic results confirmed that our species was F. saxoplanctonica, and it was the first record in Korea.

Sordariomycetes is the second largest class of Ascomycota, distributed throughout various habitat including terrestrial and aquatic environments and also existing as endophytes. We isolated endophytic fungal strains in Korea, identifying them based on their morphological characteristics and molecular analyses, using eight specific DNA regions for accurate genus identification. We identified five previously unrecorded endophytic fungal species in Korea: Chaetomium subaffine, Colletotrichum jiangxiense, Colletotrichum sydowii, Diaporthe vacuae and Neurospora tetraspora. In this study, we describe the morphological characteristics and present our phylogenetic analyses of these five fungal species.

Bamboo is host to diverse range of fungi, however, research on bambusicolous fungi remains insignificant in Korea. The genus Apiospora is prevalent in various environments, particularly as endophytic fungi in Poaceae, to which bamboo belongs. In this study, endophytic fungi were isolated from stems of Pseudosasa japonica collected from Gongjusi, Korea. To identify these endophytic fungi, we observed morphological characteristics and conducted phylogenetic analysis using internal transcribed spacer (ITS), large subunit ribosomal DNA (LSU), and β-tubulin (TUB2) DNA, identifying and describing an unrecorded fungus, Apiospora pseudosinensis.
