SUMMARY Sclerotium production by Sclerotinia sclerotiorum (Lib.) de Bary, Sclerotium rolfsii Sacc. and S. delphinii Welch was enhanced by white light, the most effective wavelengths being in the blue and near‐ultraviolet regions of the spectrum. Sensitivity of dark‐grown cultures to light decreased with age. The effect of light appeared to be through the direct induction of sclerotium initials on undifferentiated hyphae. The relevance of these observations to the general study of sclerotium morphogenesis is discussed.
