Light emission from the luminous fungus Collybia velutipes has been studied under various nutritional conditions and in no instance has growth been obtained with the complete absence of light emission. The effect of varying pH, various nitrogen and carbon sources and the response to different vitamins has been considered. Ammonium‐nitrogen or aspartic acid, glucose and pH 6.0 were shown to be most effective for optimal light emission. This isolate requires the thiazole moiety of the thiamine molecule for light emission; the effects of the thiamine antagonists pyrithiamine and oxythiamine were also studied.
