  • 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.

  • In this study, we examined myxomycetes that developed in moist chamber cultures of substrata material collected from $K{\ddot{u}}tahya$ and Konya provinces in Turkey. We collected bark samples from living trees, plant litter from the ground, standing dead wood or stumps, and downed and decayed wood or bark and placed them in the moist chamber cultures. We identified 36 species belonging to 12 genera of myxomycetes. The species determined are listed, and four new records, Didymium balearicum Ing, Macbrideola oblonga Pando & Lado, Paradiacheopsis erythropodia (Ing) Nann-Bremek. and Perichaena pedata (Lister & G. Lister) G. Lister, are added to the mycoflora of Turkey.

  • 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.

  • Recently, a severe slime mold infestation affected oriental melon plants in fields in Chilgok county, Gyeongbuk province, Korea. Specimens were collected from the fields and examined for identification. A species of Myxomycetes, Fuligo gyrosa, was identified based on its morphological characteristics. This is the first report that F. gyrosa causes slime mold of oriental melon.

  • Attempts were made to investigate the conditions of mycelia of one low-temperature type strain and one high-temperature type strain of shiitake showing poor fruit-body formation in bed-log, and to survey harmful microorganisms formed on the log surface in Gapyung County, Korea. When tested the growing ability of mycelia, the low-temperature type strain showed ca. 1.1% decrease compared with preserved original strain. And, the high-temperature type one showed ca. 8.0% decrease. The growth of isolated mycelia was tested in sawdust medium. The high-temperature type strain showed ca. 10.8% decrease compared with original strain, and the low-temperature type one showed ca. 25.1% decrease. Weight reduction rate was investigated. The high-temperature strain showed ca. 20.1% decrease and the low-temperature one ca. 19.0%. When compared with non-treatment, original high-temperature type strain showed 107.0% decrease, the isolated high-temperature type strain 49.5%, original low-temperature type one 85.4%, isolated low-temperature type one 50.0%. As the results of confrontation culture, the high-temperature type strain and the low-temperature type one were same as the original ones, respectively. And, in the bed-logs, Hypoxylon truncatum, Coriolus versicolor, Inonotus xeranticus, Daedaleopsis tricolor, Graphostroma platystoma, two species of Myxomycetes, Trichoderma sp. Hypoxylon fragiforme, H. howeianum, and Nitschkia confertula were observed as harmful microorganisms, and the bed-logs were not in good condition.

  • Studies were conducted to investigate the changes of teleomorph of Diatrype stigma on bed-log of shiitake (Lentinula edodes) and appearance of secondary harmful fungi from December 1999 to August 2001. The color of stroma was changed from red brown to dark brown after 12 months. The size of ostioles became smaller and the number of ostioles decreased as time passed. Most of the ostioles disappeared after 20 months from toleomorph formation. Perithecia and ascospores were gradually disappeared, and perithecia containing ascospores were observed at 10% of bed-logs tested after 20 months. Concerning the secondary harmful fungi infecting the bedlog of shiitake after teleomorph of D. stigma, Hypoxylon truncatum (Anamorph : Nodulisporium sp.), Schizophyllum commune and Trichoderma spp. were observed on stroma of D. stigma. Penicillium sp. occurred on spore-horn of Libertella sp. (Anamorph of D. stigma). Besides, Hypoxylon howeianum and some species of Myxomycetes were observed. Also, Libertella sp. appeared again at some bed-logs.
