Abstract
Macrofungi are visible to the naked eye and play important ecological roles in nutrient cycles as decomposers and symbionts in forest ecosystems. Collectively, macrofungi have great potential as valuable resources for food, cosmetics, and medicinal uses. We surveyed the Royal Tombs (Donggureung and Seooreung) of the Joseon Dynasty and Jongmyo Shrine, where the surrounding vegetation is well-preserved, to investigate indigenous macrofungi. During surveys in 2015-2016, we discovered six macrofungi that were previously not recorded to Korea. They were identified to the species level using morphological features and phylogenetic analysis based on the internal transcribed spacer region: Cruentomycena kedrovaya, Dacrymyces aureosporus, Laetiporus versisporus, Parasola setulosa, Piptoporellus soloniensis, and Pluteus longistriatus. The detailed morphological descriptions and molecular analysis are provided in this study.

Abstract
In 2016, as part of a larger effort to discover indigenous prokaryotic species in Korea, we isolated the family Deinococcaceae and Planctomycetaceae as unrecorded bacterial species. From the high 16S rRNA gene sequence similarity (>98.5%) and formation of a robust phylogenetic clade with known species, it was determined that each strain was a distinct bacterial species. There are no official reports that these two species have been described in Korea; therefore, the bacterial strains of Deinococcus and Blastopirellula are described for the first time in Korea. Gram reaction, colony and cell morphology, basic biochemical characteristics, and isolation sources are also described in the species description section.

Abstract
In 2016, as a part of the research program ‘Survey of Korean Indigenous Species’, diverse environmental samples were collected from various sources of freshwater, seawater, soil, wetland, reclaimed land, sand, pine forest, plant root, ginseng field, solar saltern, and caves. Thousands of bacterial strains were isolated from the diverse samples and identified based on 16S rRNA gene sequence analyses. The present study, as a phylogenetic subset of the primary research program, reports 24 unrecorded bacterial species in Korea that belong to the orders Rhizobiales and Sphingomonadales in the class Alphaproteobacteria. Based on the high 16S rRNA gene sequence similarities (>98.8%) and formation of a robust phylogenetic clade with the closest type species, it was determined that each strain belonged to each independent and predefined bacterial species. There is no official report that these 24 bacterial species have been described in Korea; therefore, 10 species of nine genera in the order Rhizobiales and 14 species of seven genera in the order Sphingomonadales are described for unreported alphaproteobacterial species in Korea. Gram reaction, colony and cell morphology, biochemical properties, and isolation sources are also provided in the species description section.

Abstract
During a series of extensive surveys of prokaryotic species diversity in Korea, bacterial strains belonging to Gammaproteobacteria were isolated from various sources of aquatic and terrestrial environments. A total of 39 isolates were obtained, which represented 39 unrecorded species in Korea belonging to 20 genera in 12 families. Enterobacteriaceae was the largest family, as eight species were assigned, which was followed by Moraxellaceae (6 species) and Pseudomonadaceae (5 species). At the genus level, Marinobacter (6 species), and Pseudomonas (5 species) were the main genera, and at least two species were obtained for Acinetobacter (3 species), Psychrobacter (3 species), Shewanella (2 species), Dickeya (2 species), Salinivibrio (2 species), Vibrio (2 species) and Rhodanobacter (2 species). The detailed description of each unrecorded species is provided.

Abstract
During a study to discover indigenous prokaryotic species in Korea in 2016, a total of 42 actinobacterial isolates were recovered from various environmental samples collected from natural cave, squid, sewage, sea water, trees, droppings of birds, freshwater, eelgrass, mud flat, sediment and soil. On the basis of a tight phylogenetic clade with the closest species and high level of 16S rRNA gene sequence similarity, it was shown that each isolate was assigned to independent and previously described bacterial species which were assigned to the phylum Actinobacteria. The following 42 species have not been reported in Korea: eight species in two genera n the order Corynebacteriales, 26 species of 16 genera in the Micrococcales, one species of one genus in the Micromonosporales, one species of one genus in the Propionibacteriales, four species of two genera in the Streptomycetales and two species of two genera in the Streptosporangiale. Cell morphology, Gram staining reaction, colony colors and features, the edia and conditions of incubation, physiological and biochemical characteristics, origins of isolation and strain IDs of 42 unrecorded actinobacterial species are presented in the species description.

Abstract
During the course of investigation of indigenous prokaryotic species in Korea, a total of 30 bacterial strains belonging to the phylum Firmicutes were isolated from diverse environmental sites such as soil, avian feces, wastewater treatment plants, fermented vegetables, seawater, algae, sea cucumber, octopus and tidal flat sediment. Phylogenetic analysis based on 16S rRNA gene sequences revealed that each strain showed high sequence similarity (≥98.7%) to the closest type strain and formed a robust phylogenetic clade with the most closely related species in the phylum Firmicutes. To date, there is no official record of these 30 species in Korea. Therefore, we report 26 species of 12 genera in the order Bacillales and 4 species of 4 genera in the order Lactobacillales which have not been reported in Korea. Morphological and biochemical characteristics, isolation sources and NIBR deposit numbers are described in the species descriptions.

Abstract
Our study aimed to discover indigenous prokaryotic species in Korea. A total of 29 bacterial species in the phylum Proteobacteria were isolated from freshwater and sediment of rivers and brackish zones in Korea. From the high 16S rRNA gene sequence similarity (≥98.8%) and formation of a robust phylogenetic clade with the closest species, it was determined that each strain belonged to an independent and predefined bacterial species. To our knowledge, there is no official report or publication that has previously described these 29 species in Korea. Specifically, we identified 10, 12, and seven species of eight, 12, and seven genera that belong to classes Alphaproteobacteria, Betaproteobacteria, and Gammaproteobacteria, respectively; all are reported as previously unrecorded bacterial species in Korea. The Gram reaction, colony and cell morphology, basic biochemical characteristics, isolation source, and strain IDs for each are also described.

Species were found in soil and litter layers of sites investigated in 2007, 2008 and 2014. Diagnoses or descriptions for these species are provided here with new micrographs or drawings.

Abstract
In 2017, during a survey of the anthozoan fauna in the Hallyeohaesang National Park in the South Sea, several Acanthogorgia specimens were collected from the subtidal zone. Through taxonomic analysis, one species, Acanthogorgia densiflora Kükenthal & Gorzawsky, 1908, was found to be previously unreported from Korea, and was, therefore, newly added to the list of Korean anthozoan fauna. This species is distributed on the slopes of the rocky substratum between depths of 14 and 24 m. Including the findings from this study, ten species of the genus Acanthogorgia have thus been reported from the Korean waters until now.
