  • Many fungal fungi were collected at Mt. Nam areas during 3 days in August 1997 and 1 day in September 1998. They were identified. According to the resulting, they were composed of 2 divisions, 3 subdivisions, 5 classes, 4 subclasses, 15 oders, 30 families, 58 genera and 95 species. Dominant species was Fomiltella fraxinea and dominant family was Tricholomataceae. Among them genera of henningsomyces, Roseoformes and Physarum were newly to Korea.

  • This study deals with the method of constructing and repairing column, important element of traditional wooden building. Column should have long-lasting strength and resistance to decay and vermin because it is more important in role of structure than in that of ornament. And the rotten or the split part of wooden column should be repaired regularly or irregularly. First of all, this study treats of general character related to the life length and strength of wood. Then it describes the technical method of choosing proper wood for column and that of carpentering, painting, and mending wooden column.

  • Hundred pieces of peat woods(ca. 2500 years old) were excavated in 1995 at Hyunwhari, Pyungtaek in the west-central coast of the Korea Peninsula. Among them, 63 samples representing 21 trenches were selected for the species identification. Because most peat woods were rotten by fungi for long period, only 27 samples could be identified. Due to the deteriorated structure of peat woods, all samples were embedded in PEG(polyethylene glycol 2000) and then sectioned using a rotary microtome. Major species were Alnus spp.(55.6%), Fraxinus spp.(33.3%) and Quercus (Lepidobalanus)(11.1%). No conifers were found. The species composition indicates that the sample region was a swamp or lakeside, which appeared to be formed because of the sea-level rise after last-glacial period.

  • Many myxomycetes were collected at Mt. Moak, Mt. Jiri, Mt. Manduck, Mt. Pangtae from June, 1996 to August, 1997. They were identified. According to the results Badhamia macrocrapa, Craterium leucocephalum, Cribraria splenden, Didymium melanospermum, D. minus, Perichaena chrysosperma, Physarum melleum, P. viride and Perichaena chrysosperma were unrecorded species in Korea. They were designed Korean common name by author. Also they will be added to list of Korean myxomycetes. Characterisctics of them were habitated on rotten wood and fallen leaves.

  • Trichoderma inhamatum KSJ1, a filamentous fungus, isolated from rotten wood showed high ability to hydrolysis of cellulosic materials. Enzyme productivity by strain KSJ1 was high in the cultivation using carbon sources such as cellulosic materials and lignocellulosic wastes as rice straw and paper waste. In previous study peptone was one of optimum organic nitrogen sources in producing cellulases for saccharification of food wastes. However, it was too expensive using peptone as organic nitrogen source, so, in this study, soybean and yeast were applicated to substitute peptone. Yeast showed producing high enzyme activity, so it was estimated that yeast is available in producing cellulase using Trichoderma inhamatum KSJ1 at industrial Production.

  • A fungus that can capture nematodes by means of sessile adhesive knobs was isolated from rotten wood in Uiseong, Korea. It was found to produce single, spindle-shaped, 3-4 septate (commonly 4-septate) conidia, $44.8\;{\mu}m$ (range, $41.6-50.1\;{\mu}m$) long and $13.3\;{\mu}m$ (range, $10.7-15.4\;{\mu}m$) wide. Conidiophores were found to be hyaline, erect, straight, and $202.7-245.7\;{\mu}m$ high. On the basis of these morphological features, the fungus was identified as Monacrosporium phymatopagum. This is the first report of M. phymatopagum in Korea which can be a potential biological control resource of plant parasitic nematode.

  • Many myxomycetes were collected at Pyunsan penisula national park, Mt.Moak, Mt.Minjuji, Mt.Manrae, Wanju, Mt.Unjang from July, 1996 to August, 2000. They were identified. According to the results, Amaurochaete tubulina, Cribraria microcarpa, Cribraria splendens, Diachea leucopodia, Entreridium lycoperdon, Stemonitis flavogenita and Stemonitis fusca were unrecorded species in Korea. Characterisctics of them were habitated on rotten wood and fallen leaves. They were designed Korean common names by author.

  • Subsocial woodroaches of Cryptocercus occur in high mountainous forests in temperate regions and they live in a family in complicated galleries of rotten logs. A prominent feature of the geographical distribution of Cryptocercus is the wide disjunction between the eastern and western species in North America, and between West China and Northeast Asia. Recently, five species of the genus were added from Asian areas and two of them are distributed in Northeast Asian areas. We examined morpho-anatomical structures of male genitalia in Manchurian and Korean Cryptocercus, focusing on male genital hooks and subgenital plates.
