Summary

In an electron microscopic study on the dikaryotic hyphae ofSchizophyllum commune, microtubules were observed during the nuclear division, and close to the non-dividing nuclei of apical cells and older cells. Microtubules of the spindle were connected with semicircular bodies at nuclear poles. Microfilaments were detected in the distal part of the apical cells. Vesicles similar to those in the tips of the hyphae occured also at the sites of septa formation. The occurrence of microtubules and the structure of semicircular bodies are compared with those in other basidiomycetes. It is suggested that vesicles are involved in the primary growth of the septal cross wall.
