Occurrence and Distribution of Cellular Slime Molds in South Korea

An investigation of occurrence and distribution of dictyostelid cellular slime molds in South Korea were carried out. Thirty-one dictyostelid cellular slime molds were isolated from soils of 256 sample sites of 41 area within mountain forests, riversides, streamsides and coastal area in South Korea. The average number of species isolated at a given study area was 6.85. Based on the distribution value calculated from average frequency and site presence, four dictyostelid species distributed widely in South Korea; Polyspondylium pallidum, P violaceum, Dictyostellium mucoroides and D. minutum. Especially, P pallidum. were found in 30 area and the highest site presence. Eight dictyostelid species was described firstly in this study: D areum var. luteolum, D. delicatum, D. deminutivum, D. implicatum, D. microsporum, D. mucoroides var. stoloniferum, D septentrionalis, and P. candidum.
