In Physarum gyrosum (white) a single pigment is identified and characterized as a flavone. Physarum polycephalum (yellow) and Didymium iridis (brown) contain four and six components, respectively, in their plasmodial pigments which test negatively for flavones but show the presence of some type of phenolic compound. No detectable component is identified in the white plasmodium of Didymium squamulosum which proved to be independent of light for fruiting. The absorption spectra of all species that were light sensitive for fruiting showed common peaks in the 300–400-mμ region, among others. Pigment changes associated with light absorption are reported for some white, yellow and brown plasmodial types. In Physarum gyrosum a yellow pigment forms in light which did not show the characteristic flavones present in the white plasmodial stage. Changes in absorption spectra are reported for Physarum polycephalum, Didymium iridis and Didymium squamulosum as the plasmodial pigments change prior to fruiting. Results show a close relationship between the physiology of plasmodial pigmentation and sporulation in the Myxomycete species studied.
