Species composition and density of Dictyostelid cellular slime molds in Quercus mongolica var. grosseserrata-Betula platyphylla var. japonica forests around the Kushiro moor, Hokkaido, Japan, were investigated by means of a clonal isolation technique. Seven species of cellular slime molds were isolated from the soil samples of fifteen sites. Absolute densities, relative densities and frequencies of the cellular slime molds at each collecting site and presence values of each species throughout the study area were calculated. Dictyostelium mucoroides, D. minutum, Polysphondylium violaceum, and P. purpureum were common and widespread. D. mucoroides was relatively dominant in absolute density. Most of the cellular slime molds were distributed between leaf litter and surface humus layer within the forest soil. The absolute density of cellular slime molds decreased as the soil depth increased.
