An action spectrum for carotenogenesis in V. agaricinum has maxima at 395, 433, 660 and 737 nm. In a previous study it had been shown that a light‐minus‐dark difference spectrum of a crude extract from V. agaricinum had maxima at 390 and 420 nm, and furthermore a red, far‐red interaction suggesting phytochrome involvement has been proposed. All these data suggest that there may be at least two photoreceptor systems operating in the photoinduction process here; one for the near‐ultraviolet (UV‐A)‐mediated carotenogenesis, presumably a novel pigment, and the other for the red, far‐red region, most likely phytochrome.
