✦ Synopsis

Measurements of nuclear positions in apical cells of homokaryotie mycelia and dikaryotie mycelium of Schizophyllum commune showed that nuclei occupied a near central position in most cases. Forward nuclear movements observed in living hyphal apices occurred at rates within the range of hyphal growth and could account for the maintenance of centrally located nuclei. Opposed nuclear movements followed mitosis and greatly exceeded the rate of hyphal growth. Scptum disruption and rapid nuclear movements characterized an A~B,,~t homokaryon. Neither cytoplasmic streaming nor actively participating granules or filaments could account for any of these nuclear movements.
