Effect of light on the development of Saccobolus platensis

The ascomycetous fungi Saccobolus platensis requires light for apothecial production. Photoinduction could be accomplished by continuous light and also by minor light periods. When apothecia were photoinduced by single 24 hour photoperiods, the effect varied according to the stage of development of...
