Under conditions of growth limitation the germ tubes of Neurospora crassa macroconidia may convert to functional conidiophores with developing chains of viable, new conidia. The induction of this paedogenetic conidiation in liquid culture does not require exposure to high temperature, as reported for conidia of some other ascomycetous fungi, but it is induced at normal growth temperatures within 12-15 h by germination of the conidia in a dilute, nutrient-poor incubation medium. The inoculum density, temperature of incubation, presence or absence of white light, and genetic strain of N. crassa also influence the kinetics of conidium formation.
