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.

This study was carried out to investigate occurrence and distribution of cellular slime molds by vegetation in Mt. Seorak. Eleven species were isolated from surface soil samples as follows: P. violaceum, P. candidum, P. purpureum, D. brefeldianum, D. minutum, D. delicatm, D. crassicaule, D. macrocephalum, D. firmibasis, D. polycephalum and D. implicatum. The dorminant species was D. brefeldinum. D. delicatum, D. implicatum, D. polycephalum and P. candidum of them were isolated rarely in Korea. It can be thought that these results were caused by characteristics of forest zone and geographical condition which Mt. Seorak is located at east side of central areas of Korea.
