Five dictyostelid cellualr slime molds were found in forests of Pinus densiflora and Quercus mongolica in Mt. Surak, uijeongbu, Kyunggi-do, South Korea. isolates were Polysphondylium pallidum, Dictystelium firibasis, D. crassicaule, P. tennuissimum and D. valenstemmum. Dominant soecies was P. pallidum. This species had occurred widely in South Korea as well as in the world. Especially, new dictyostelid, D. valenstemmum shim et Chang, was found in the fermentation layer of P. densiflora and Q. mongolica mixed-forest soils. D. firmibasis had not been described until now and found in the mountain forests.

thirteen dictyostelid cellular slime molds were isolated from forest soils, cattle dung and manure inisland Ulneungdo, South Korea. They were ten species including Dictyostelium aureo-stipes var. aureo-stipes, D. brefeldianum, D. macrocephalum, D. caudabasis, D. sphaerocephalum, D. giganteum, D. crassicaule, Polysphondylium pallidum, P. violaceum and P. tenuissimum as well as three species unidentified. D. aureo-stipes var. aureo-species of genus Polysphondylium distributed widely. It was thought that species diversi쇼 was considerabley higher.

The occurrence and distribution of dictyostelid cellualr slime molds were investigated in forests of Mt. Paektu. Fourteen species were isolated from forest soils of thirteen sites as follows Dictyostelium minutum, D. brefeldianum, D. crassicaule, D. capitatum, D. mucoroides var. stoloniferum, D. macrocephalum, D. mucoroides, D. septentrionalis, D. purpureum, D. aureo-stipes, P. violaceum, P. pallidum and two unidentified speceis. Mean total clones and species found were 4,415.69 No./g and 2.92, respectively. Dominant species were D. minutum, D. brefeldianum and D. crassicaule in this study area, and first widespread species was D. minutum. All sepecies that found in Mt. Paektu were isolated from forests of South Korea. But dominant species was different from those of South Korea. Total clones and species were more in subalpine Eurya japonica than in low elevated abies nephrolepis. It was thought that distribution of dictyostelids was related to soil microenvironments by vegetation, not or not more elevation.
