Abstract
IT has been observed1 in the homothallic fungus Rhizopus sexualis (Smith) Callen that the initiation and early stages of maturation of zygospores, which at 20–25° C. occur within a few days of inoculation, are completely inhibited at temperatures below 10° C. Later stages in the maturation of zygospores initiated at room temperature and afterwards transferred to low temperature are not inhibited; this suggests that a possible cause of the inhibition is a block in the synthesis of some compound or compounds essential for the early stages of zygospore production.
