Iodophanus carneus requires light for apothecial production. When apothecia were photoinduced by single 24 hour photoperiods, the effect varied according to the stage of development of the mycelium: it was most receptive at the 5th day of growth, but an inhibitory effect on apothecial formation was evident in cultures exposed in the 1st, 2nd or 3rd day of growth. A minimum single exposure of 10 s was required for apothecial development, whereas a single exposure of 4 h was required for asci development. Maximum production of apothecia was found in those cultures exposed to constant light at 100 b/p. The localization of apothecial differentiation was evident in predictable areas. The concentration of glucose affected stimulatory and inhibitory effects of light on fruit-body formation.
