SUMMARY
Disc electrophoresis was run on proteins from 14 myxomycete isolates in the order Physarales. The combination of profiles produced to general protein, esterase, phosphatase, amino peptidase and peroxidase stains is distinct for each species. Similarities in profiles to some stains cross generic and specific lines. Possibly the pigmentation system contributes to these similarities. The disc electrophoretic technique appears useful in delineating myxomycete species.
