  • 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.

  • Four unrecorded species (Barbella flagellifera, Isothecium hakkodense, Mnium orientale and Fissidens gardneri) and with one unrecorded genus, Barbella, are reported new to the Korean moss flora. B. flagellifera (Meteoriaceae) was found on a tree at alt. 300-350 m of parasitic Seogeomun-oreum Volcano on Jeju Island. The species are mainly distributed in subtropic regions. I. hakkodense (Lembophyllaceae) was found around the top of Seongin-bong on Ulleung Island. This species is similar to I. subdiversiforme, however, it can be distinguished by the morphologies of branch leaves and alar cells. M. orientale (Mniaceae) was collected from Mt. Jiri. This is similar to M. heterophyllum, however, it can be distinguished by plant size, number of teeth in leaf margin and cell size on leaf. F. gardneri (Fissidentaceae) was found along the valley of Mt. Palyeong, Jeollanam Province. This species is similar to F. obscurirete, but distinguished by the size of the plants and their leaves as well as the costal lengths of the leaves.

  • The phylum Bacteroidetes covers phenotypically diverse groups of Gram negative rods that do not form endospores, and currently includes 6 classes, 6 orders, 33 families and 380 genera. Members of Bacteroidetes can be aerobic and anaerobic heterotrophs, hydrogen utilizing chemolithotrophs, or methylotrophs. They can be isolated from diverse habitats including terrestrial and aquatic environments, environments with extreme physicochemical conditions, and animal and plant hosts. During a series of extensive surveys of prokaryotic species diversity in Korea, bacterial strains belonging to Bacteroidetes were isolated from various sources of aquatic and terrestrial environments. A total of 22 isolates were obtained, which represent 22 unrecorded species in Korea belonging to 14 genera of 6 families. Sixteen species among them were assigned to Flavobacteriaceae, two species were to Sphingobacteriaceae, and single species was to each of the families Bacteroidaceae, Balneolaceae, Chitinophagaceae and Cytophagaceae. At genus level, Chryseobacterium (5 species) and Flavobacterium (5 species) were the most abundant genera, and single species were obtained for the genera Bacteroides, Baloneola, Terrimonas, Dyadobacter, Aquimarina, Arenibacter, Gillisia, Gilvibacter, Salinimicrobium, Winogradskyella, Pedobacter and Sphingobacterium. The detailed descriptions of each unrecorded species are provided.

  • 151 strains which belong to the gens Rhizopus were isolated from 750 specimens collected through all over South Korea, and 19 species of the genus, all of which are unrecorded in Korea, were identified according to the modified Takeda-Yamamoto's classification key. The species identified are as follows ; R. nigricans, R.formosaensis, R.achlamydosporus, R.tritici, R.javanicus, R.cuiuniang, R liquefaciens, R.chungruoensis, R.acidus, R.chinensis, R.delemar, R.hangchow, R.japonicus, R.arrhizus, R.bahrnenesis, R.tonrinensis, and R.shanghaiensis.

  • The present genus, once applied as an all-round taxon on resupinate polypores, was considered on account of its common occurrence throughout the world and outstanding wood-rotting nature. In Korea two species, P. vaporaria(but even this seems misjudged) and P. cocos have been known. The authors used to examine tentatively the materials formerly preserved in dried state. Among about 40 collections half of them was recognized as P. cocos and 4 unrecorded species, P. versipora, P. subacida, P. medulla-panis, and P. eupora, which are newly registered to Korea in this article.

  • Dried specimens of the genus Inocybe collected from mountain areas throughout the Korean country from 1982 to 1998 and preserved in NIAST were investigated. Out of them, Inocybe hystrix were confirmed as an unrecorded species in Korea. In 1991 Lee et al., previously recorded Inocybe kasukayamensis only with its scientific name and korean common name. In this study we report it with full descriptions of morphological characteristics and diagnosis of micro-structures of this species.
