Plasmodial extracts of 45 isolates of Fuligo septica (L.) Wiggers selected from diverse geographical areas were subjected to acrylamide disc electrophoresis. Profiles for ten enzymes and general protein were determined. Profile variability among isolates occurred. Indices of similarity calculated for each isolate indicated that the variations of the yellow and white plasmodial isolates fell within different ranges. Determination of the total range of variation for the species must wait on the analysis of more white isolates. The extreme sensitivity of disc electrophoresis in detecting color forms suggests it can be useful as a tool in myxomycete taxonomy.
