Evidence is presented showing that intensity of light emission in dikaryotic cultures of Panus stipticus, Armillaria mellea, and Mycena polygramma follows a diurnal pattern. The lowest values appear between 6 and 9 A.M. and the peak intensities occur between 6 and 9 P.M. This pattern is consistent regardless of whether the cultures are grown in total darkness, under constant illumination, or exposed to a normal day-night cycle.
