It was found that light is required for the initiation and development of fruit-bodies in Favolus arcularius. The effect of light lasted for about one day after transfer to darkness. The mycelium became sensitive to light about 2.5 days after inoculation; i.e., at the beginning of the rapid growth phase. The site of fruiting was 2-5mm inside the edge of colony (actively dividing zone) at the start of illumination. When one half of the plate culture was illuminated, fruiting was restricted to the illuminated half of the colony; i,e., the effect of light was localized. These results suggest that the cells sensitive to light are the actively dividing cells. Under a fixed light intensity, the total irradiation time required for the initiation of fruiting was nearly constant, irrespective of the durations of pre-incubation in darkness and the daily illumination period. With in creasing light intensities, up to about 500 lux, fruiting was promoted, however, a further increase in light intensity was inhibitory.
