  • Soil is a rich source of saprobic and pathogenic fungi in crop cultivation areas. Compared with that of the fruit trees, scarce information is available regarding the fungi present in orchard soils in Korea. We sampled rhizosphere soils of apple and pear trees from several orchards in Cheongju, Anseong, and Cheonan, Korea. During the processing of soil fungi, seven unrecorded species of the phylum Ascomycota were isolated. These included Acrocalymma walkeri, Clonostachys krabiensis, Coniella vitis, Cosmospora diminuta, Lasiobolidium spirale, Penicillium vallebormidaense, and Pseudothielavia arxii. All the species were identified and described based on morphological characteristics and molecular analysis of the ITS1-5.8S-ITS2 region and the large subunit of nuclear ribosomal RNA gene and partial β-tubulin gene (BenA) sequences. Descriptions and illustrations of the morphological characteristics are provided.

  • Fire blight, a plant disease caused by Erwinia amylovora, continues to cause considerable damage to fruit-bearing trees belonging to the Rosaceae family, such as apples and pears. In Korea, to hinder its rapid spread diseased apple and pear trees have been buried since its first occurrence. To determine the safety of this control method, the buried plant materials and adjacent soil have been investigated. In the process of investigating the microbiota of the buried soil, Bisifusarium allantoides, Botryotrichum domesticum, Microascus verrucosus, Paraphoma pye, Phaeosphaeria culmorum, Ramophialophora globispora, Sordaria tomentoalba, and Striaticonidium brachysporum were identified as unrecorded species in Korea. To report the above eight species as Korean unrecorded species, we report their morphological and molecular features in this study.

  • As a subset study for the collection of Korean indigenous prokaryotic species, 62 bacterial strains belonging to the phylum Actinobacteria were isolated from various sources. Each strain showed higher 16S rRNA gene sequence similarity (>98.75%) and formed a robust phylogenetic clade with closest species of the phylum Actinobacteria which were defined with valid names, already. There is no official description on these 62 actinobacterial species in Korea. Consequently, unrecorded 62 species of 25 genera in the 14 families belonging to the order Actinomycetales of the phylum Actinobacteria were found in Korea. Morphological properties, basic biochemical characteristics, isolation source and strain IDs are described in the species descriptions.

  • Culturable bacterial diversity was investigated using freshwater and sediment samples collected from the North Han River basin in 2017, as a part of the research program 'Survey of freshwater organisms and specimen collection'. Over a thousand bacterial strains were isolated from the samples and identified based on 16S rRNA gene sequences. Among the bacterial isolates, 22 strains showing higher than 98.7% sequence similarity with validly published bacterial species, but not reported in Korea, were classified as unrecorded species in Korea. The 22 bacterial strains were phylogenetically diverse and assigned to 6 classes, 11 orders, 15 families, and 21 different genera. At the generic level, the unreported species were affiliated with Flavobacterium of the class Flavobacteria, Flexibacter of the class Cytophagia, Blastomonas, Brevundimonas, Elstera, Rhizobium, Roseomonas, Sphingomonas, and Xanthobacter of the class Alphaproteobacteria, Albidiferax, Cupriavidus, Curvibacter, Ferribacterium, Hydrogenophaga, Iodobacter, Limnohabitans, Polaromonas, Undibacterium, and Variovorax of the class Betaproteobacteria, Pseudomonas of the class Gammaproteobacteria, and Arcobacter of the class Epsilonproteobacteria. The unreported bacterial species were further characterized by examining Gram reaction, colonial and cellular morphology, and biochemical properties. The detailed descriptions of 22 strains of the unreported bacterial species are also provided.

  • In 2019, 43 bacterial strains were isolated from food, soil, marine environments, human, and animals related sources from the Republic of Korea. Based on the analysis of 16S rRNA gene sequence, these isolates were allocated to the phyla Bacteroidetes and Firmicutes as unrecorded species in Korea. The 10 Bacteroidetes strains were classified into the families Bacteroidaceae, Chitinophagaceae, Cytophagaceae, Flavobacteriaceae, and Prolixibacteraceae (of the orders Bacteroidales, Chitinophagales, Cytophagales, Flavobacteriales, and Marinilabiliales, respectively). The 33 Firmicutes strains belonged to the families Bacillaceae, Paenibacillaceae, Planococcaceae, Staphylococcaceae, Clostridiaceae, Lachnospiraceae, Peptostreptococcaceae, Enterococcaceae, Lactobacillaceae, Leuconostocaceae, and Streptococcaceae (of the orders Bacillales, Clostridiales, and Lactobacillales). These unrecorded bacteria were determined based on taxonomic criterion (>98.7%; 16S rRNA gene sequence similarity). In addition, their phylogenetic affiliation, as well as cell and colony morphologies, staining reactions, and physiological and biochemical properties were investigated. Therefore, we report 43 isolates as unrecorded species, and described basic features, isolation source, and locations of these strains.

  • Prunus speciosa (Koidz.) Nakai belonging to Prunoideae of Rosaceae, a species previously unrecorded in Korean flora, is described. Prunus speciosa (Koidz.) Nakai is similar to Prunus sargentii Rehder and Prunus jamasakura Siebold ex Koidz., but different because it has toothed lobes of calyx tubes with the apex of leaf serrations aristate. This species is naturalized widely in the eastern parts of Jeju Island but is endemic to Japan.

  • During a week from 6th August in 1976 to survey the fungal flora on higher fleshy fungi around Mt. Jogye 193 specimens were collected and then examined tentatively. As a result fo identification except several troublesome ones it was known that they lie within 66 genera, 110 species, 3 varieties, and 2 forms. Out of them five genera, Eutypa, Sarcosoma in Ascomycetes, and Corticium, Heimiella, Clitopilus in Basidiomycetes were confirmed as unrecorded genera to Korea. And therefrom 26 species and 1 form corresponding almost to the fourth of sum were identified as unrecorded species to Korea, among which Basidiomycetes are provided with descriptions and figures in this survey report.
