  • Ostrea denselamellosa and Eriocheir japonica samples were collected from the Seomjin River in 2019 as part of the "Research of Host-Associated Bacteria" research program. Almost 200 bacterial strains were isolated from the O. denselamellosa and E. japonica samples and subsequently identified by 16S rRNA gene sequencing. Among the bacterial isolates, ten strains possessed greater than 98.7% sequence similarity with published bacterial species that had not previously been recorded in Korea. These species were phylogenetically diverse, belonging to three phyla, four classes, seven orders, and eight genera. At the genus and class level, the previously unrecorded species belonged to Pseudoalteromonas, Aliivibrio, Rheinheimera, Leucothrix, and Shewanella of the class Gamma-proteobacteria, Olleya of the class Flavobacteriia, Algoriphagus of the class Cytophagia, and Lactococcus of the class Bacilli. The previously unrecorded species were further characterized by examining their Gram staining, colony and cell morphology, biochemical properties, and phylogenetic positions.

  • To obtain unrecorded bacterial species from Korean islands, various samples were collected from the islands in 2022. After plating the samples on marine agar or Reasoner's 2A, and incubating aerobically, approximately 1,200 bacterial strains were isolated and identified using 16S rRNA gene sequences. A total of 10 strains showed ≥98.7% 16S rRNA gene sequence similarity with the bacterial species that were validly published but not reported in Korea. The unrecorded bacterial strains belong to three phyla, five classes, 10 orders, 10 families, and 10 genera, which are assigned to Sphingomonas, Falsirhodobacter and Asticcacaulis of the class Alphaproteobacteria; Colwellia and Halomonas of the class Gammaproteobacteria; Chitinophaga of the class Chitinophagia; Chryseobacterium of the class Flavobacteriia; Microlunatus, Zhihengliuella, and Streptomyces of the class Actinomycetia. The details of the unreported species including Gram reaction, colony and cell morphology, biochemical characteristics, and phylogenetic position are also provided in the description of the strains.

  • Five unrecorded species (Oedipodium griffithianum, Myurella tenerrima, Trachypus bicolor, Coscinodon humilis, Meteorium miquelianum subsp. atrovariegatum) with one unrecorded family and two unrecorded genera, were reported as new to the Korean moss flora. The monotypic family Oedipodiaceae consisting of a single genus and single species was distinguished from Splachnaceae by small plants that were 10 mm in length simple or sometimes branched, obovate-spathulate to ${\pm}$ orbicular, costa ending below the apex and entire margins except for the lower long-ciliate portion The species was first found at the top of the Mt. Seorak at an altitude of 1708 m. The two genera, Myurella and Coscinodon were found in the Korean Peninsula. Myurella tenerrima (Theliaceae) was found around the top of Jung-bong on Mt. Jiri. It was mixed with other mosses in the crevices of rocks in the alpine regions. The species is similar to M. sibirica, yet it can be distinguished by the position of papilla in the median laminal cells. Coscinodon humilis (Grimmiaceae) were found on the ridge of Mt. Gaya. C. humilis has a variety of hyaline apex according to leaf position and forms a capsule so it can be distinguished by family. Trachypus bicolor and Meteorium miquelianum subsp. atrovariegatum are unrecorded species. T. bicolor (Trachypodaceae) were found on the ridge of Mt. Gaya. T. bicolor is similar to T. humilis but distinguished by the costal lengths of the leaves. M. miquelianum subsp. atrovariegatum (Meteoriaceae) was found in Gageo-do. This species was distinguished by the plant form and morphology of stem leaves in the same genus.

  • Fungi act as important decomposers in the forest environment. They recycle essential nutrients, promote plant growth through mycorrhizal relationships, and act as food for small animals. Samples of 265 indigenous fungal species were collected from Mudeungsan National Park in 2020. These species were identified based on morphological, molecular, and phylogenetic analyses using the internal transcribed spacer (ITS), nuclear large subunit rRNA (LSU), and RNA polymerase II second largest subunit (rpb2) regions. Subsequently, seven species were identified as unrecorded species in Korea: Cordyceps cicadae, Dentocorticium bicolor, Hymenochaete nanospora, Physisporinus crataegi, Rigidoporus piceicola, Russula raoultii, and Scutellinia crinita. This study reveals their detailed macro- and microscopic morphological characteristics with phylogenetic trees to report them as unrecorded species in Korea.
