Abstract: | Summary An action spectrum of light induced coremia-zonation was obtained for the fungus Penicillium claviforme mut. olivicolor Abe et Ura. Zonation is induced only by light of wavelengths shorter than 510 nm. The action spectrum has maxima at 370 nm and at 450–460 nm and a definite shoulder at 470–480 nm. Penicillium claviforme mut. album is somewhat less sensitive to light but possesses the same spectral sensitivity.Measurable amounts of carotenoids are not found in the mycelium. The presence of diphenylamine in the nutrition medium has no effect on the fungal sensitivity to light. It is therefore assumed that the photoreceptor pigment involved is a flavoprotein.
