Some effects of light and temperature on fruiting of Coprinus lagopus in pure culture are described. Fruiting, which in darkness did not commence until about the 15th day, was accelerated by continuous light or by brief exposures to light between the 7th and 13th days of incubation. Very small exposures sufficed, provided they were of a wavelength no longer than that of green light, the response being restricted to the area of mycelium actually exposed. In both light and dark a temperature near 25° C. was optimal for growth and fruiting.
