The seven unrecorded ciliates were collected from soil samples in Korea. The morphological study of these ciliates was performed based on observation of both living and stained cells: Rigidocortex quadrinucleatus Bharti, Kumar and La Terza, 2017, Rigidohymena tetracirrata (Gellért, 1942) Berger, 2011, Urosoma salmastra (Dragesco and Dragesco-Kernéis, 1986) Berger, 1999, Urosomoida agilis (Engelmann, 1862) Foissner, 1982, Rigidosticha italiensis Bharti, Kumar and La Terza, 2016, Eschaneustyla terricola Foissner, 1982 and Pseudokeronopsis similis (Stokes, 1886) Borror and Wicklow, 1983. Among the seven genera in this study, the genus Rigidosticha Bharti, Kumar and La Terza, 2016 is firstly reported in Korea. In this study, we provide brief descriptions and remarks for the ciliates with photographs.

Leuzea chinensis (S. Moore) Susanna (Asteraceae), a previously unrecorded species in Korea, was found in Yeongdeok-gun, Gyeongsangbuk-do. Symplocos nakaharae (Hayata) Masam. (Symplocaceae), which had been recorded in the literature but whose native habitat was yet to be identified, was found in Geojedo Island, Gyeongsangnam-do. It was confirmed that Epilobium parviflorum Schreb. (Onagraceae) grew naturally on the islands of Jeollanam-do. Detailed morphological descriptions and geographical distribution of the three taxa are provided.

Thirty three entomopathogenic species belonging to twelve genus were collected throughout 16 collecting sites from 1990 to 1996. Among those collected species, 14 unrecorded species such as Cordyceps bifusispora, C. martialis, C. oxycephala, C. paludosa, C. pentatomi, C. rosea, C. ryogamiensis, Shimizuomyces paradoxa, Akanthomyces aculeatus, Polycephalomyces ramosus, Tilachlidiopsis nigra were added to Korean entomopathogenic species through this study. In nature, occurrence of Cordyceps nutans, C. sphecocephala and Paecilomyces tenuipes were from early June to late September. On the other hand, C. militaris, C. kyushuensis and C. pruinosa were mainly found from mid July to mid August when relative humidity are increased. Nine species of the genus Cordyceps including C. bifusispora and four deuteromycetous species were isolated. As a result of cultural test using six Cordyceps species, anamorph of C. militaris, C. kyushuensis were proved as Verticillium sp. C. pruinosa as Acremonium sp., C. sphecocephala as Hymenostilbe sp. and C. scarabaeicola as Beauveria sp., respectively.

Fresh fungi were collected during field trips to mountain areas throughout the country from May to October of 1994. Through the observation and identification of specimens belonging to the Aphyllophorales, two genera, Botryohypochnus and Vesiculomyces, and seven species, Botryohypochnus isabellinus, Phanerochaete laevis, Vesiculomyces citrinus, Gloeoporus pannocinctus, Junghuhnia luteoalba, Inonotus andersonii, and Inonotus hispidus, were confirmed new to Korea and are registered here with descriptions.

Flesh fungi were collected during field trips to mountain areas throughout the country from May to October of 1994. Through the observation and identification of specimens belonging to the Aphyllophorales, one genus, Tylospora, and six species, Athelia fibulata, Hypochnicium punctulatum, Tylospora fibrillosa, Stereum ochraceo-flavum, Steccherinum litschaueri, and Oligoporus undosus were confirmed new to Korea and are registered here with descriptions.

The goal of this study was to elucidate wild yeast diversity of the midstream region of the Geumgang river, Gongju, Chungnam province, Korea. Fifty strains of 24 species of wild yeasts were isolated from 45 water and soil samples among which Cryptococcus spp. (11 strains), Cryptococcus magnus (7 strains), Rhodotorula spp. (9 strains), and Hanseniaspora spp. (6 strains) were dominant. Four species, Candida chauliodes WJSF 0201, Candida oleophila WJSF 0202, Candida catenulata WJSF 0203, and Candida jaroonii WJSF 0204, represented newly recorded yeasts in Korea. All of these unrecorded yeasts were oval in shape, formed ascospores and pseudomycelium, and grew in vitamin-free medium. Candida oleophila WJSF 0202 was thermophilic which can grow at $37^{\circ}C$.

We investigated about change of dinoflagellate composition during October 2006 to November 2007 at the Chagwi-Do, west-part of Jeju Island. There were 32 dinoflagellate species in collected samples and 19 species Amphisolenia bidentata, Ceratium gravidum, C. hexacanthum, C. platycorne, C. praelongum, C. ranipes, C. reflexum, C. geniculatum, Dissodinium elegans, D. bicorne, Ornithocercus heteroporus, O. magnificus, O. quadratus, O. splendidus, O. steinii, Protoperidinium excentricum, Pseliodinium vaubanii, Ptychodiscus noctiluca, Pyrocystis hamulus of collected dinoflagellate species were rare and unrecorded species from around the Korean Peninsula. The quantities by month of these tropical oceanic species, Ornithocercus were 28, 22, 0, 3 and $502\;cells/m^3$ in October 2006, February, April, September and November 2007 respectively. The abundance of genus Ornithocercus for whole dinoflagellate species were 8, 3.9, 0, 0.2 and 97.9% respectively. These results suggest that the coast of Korean Peninsula is getting warm by global warming.

Four fungal species, during indoor air monitoring for fungi that possibly affect the field testing of a newly bred shiitake cultivar in cultivation houses located in Cheongyang, Chungnam Province and Jangheung, Jeonnam Province. Of these species, two are known to be plant pathogens and the other two are saprobes but potent contaminators in the mushroom cultivation environment. This study reports the morphological characteristics and phylogenetic relationships of these four species based on nucleotide sequences of the internal transcribed spacer (ITS) and 18S rDNA region, including their known information.

During a survey of the activities of fungi in steamed sweet potato, stored garlic, agricultural by-products for mushroom cultivation media, and pinewood chips from a pinewood nematode-infected tree, numerous fungal samples were isolated and identified. This study identified five species that have not been previously reported in Korea, namely Geomyces pannorum, Neopestalotiopsis javaensis, Penicillium allii, Penicillium chermesinum, and Ophiognomonia setacea. For all identified species, the cultural features of colonies formed on growth media, their morphological characteristics observed by a light microscope, and their molecular phylogenetic relationships based on nucleotide sequences of the internal transcribed spacer rDNA region or calmodulin gene were described.

Wood-rotting fungi were collected in Suweon campus of Seoul National University from September 1981 to October 1982. These fungi were classified into 2 orders, 8 families, 22 genera and 34 species. Of these, Gloeoporus adustus (Willd. ex Fr.) $Pil\acute{a}t$ and G. dichrous (Fr.) Bres. were found to be new species that belong to unrecorded genus in Korea. Korean common names of these two new species were designated by the authors. List of the wood-rotting fungi was given with the generic name of host trees on which the fungus was collected.
