Occurrence and distribution of the celluar slime molds in relation to the coastal plant communities of svven islands near inch'on wereinvestigated. as a results, total seven species were isolated from the soils of the coastal plant communities. These are dictyostelium mucoroides, polysphodylium pallidum, dictystelium polycephalum. d. mucoroides was the most commonly found in the coastal plant communities investigated, and was dominant pecularly in the coastal mixed forests, the coastal broad-leaved forests and salt marshes. In the coastal coniferous forest and the coastal dune sand plants, hoeever, p. violaceum was the dominant species. species diversity was relatively was relatively high in the coastal coniferous ferests and the coastal mixed forests. However, agerage number of species isolated from all plant communities was very low,2.8.

In this study, the occurrence and distribution of dictyostelid cellular slime molds was investigted from soils of typical forests in Mt. Nam and the effect of soil environmental factor on cellular slime molds was investigated. The fourteen species including two undescribed species were isolated as follows: Dictyostelium brefeldianum, Polysphondylium pallidum, P. violaceum, P. pseudo-candidum in Quercus mongolica-Sorbus alnifolia forests, D. purpureum, D. mucoroides var. stoloniferum, D. dimigraformum, D. brefeldiamum, P. pallidum, P. tenuissimum, P. violoceum, P. candidum, P. pseudo-candidum in Pinus densiflora forests, D. polycephahum, D. capitatum, d. brefeldianun, P. candidum in Robinia pseudo-acacia forests, D. purpureum, D. aureostipes var, aureostipes, D. polycephalum in Quercus acutissima forests, D. minutum, D. implicatum. in the site disturbed by human. The dominant species were P. pallidum, D. brefeldiamum, P. pseudo-candidum and D. dimigraformum were the undescribed species in Korea. Environmental factors such as soil pH, water content, organic content, total nitrogen and total phosphorus made a little effect on total species number, the number of clones.

Dictyostelid cellular slime molds isolated quantitatibly from the oils of evergreen broad-leaved forest and moist grassland of mt. halla in korea. nineteen species were found, including four undescribed species. species underscribed in korea are dictyostelium aureum var. aureum, d. crassicaule, d. monochasioides, and polysphondylium tenuissimum. Among these isolates, d. crassicaule and d. monochasioides were found only in evergreen broad-leaved forest, and p.tenuissimum was commonly found in moist grassland and meadow. in warn temperate regions investigated, d. mucoroides occurred rarely. It was noticeadle that d. sphaerocephalum, d. aureum var. aureum and d. purpureum were much more commonly found in warm temperate region. Species diversity in evergreen broad-leaved forest was the highest among the forests investigated until now in korea. Many isolates in mt. halla distributed differently in relation to the vegetations and altitudes. distritution patterns of isolates from mt. halla were discussed.

Dictyostelid cellular slime molds were quantitatibly isolated from the soils of mt.halla (above 900m in altitude), korea, according to the 'clonal isolation technique(cavender and raper, 1965a)'. Total fifteen species were found, including 1 new and 6 undescribed species.these are dictyostelium mucorodes, dictostelium minutem,polysphondylium pallidum fasciculatum, polysphondylium violaceum, dictyostelium flavidum,dictyostelium fasciculatum, polysphondylium violaceum, dictyostelium flavidum sp. n.(HL-1),dictyostelium aureo-stipes var. aureo-stipes, dictyostelium capitatum, dictyostelium giganteum,dictyostelium polycephalum,dictyostelium brefeldianum,dictyostelium macrocephalum, and dictyostelium sphaerocephalum, dictyostelium sp. (HL-2), dictyostelium sp. (CJ-9). D. mucoroides was the dominant species, and D. minutam,p.pallidum, d. fasciculatum, and p. violaceum were relatively common. d. polycephalum, d. brefeldianum, d. macrocephalum, dictyostelium sp. (HL-3), and d. sphaerocephalum were very rare. Species diversity appeared to be the highest in the deciduous broad-leaved forest from the soils of which 14 species were isolated. eight species were, including five undescribed species, isolated only from this forest soils. Number of isolates severely decrease at the forests above 1,500m in altitude.
