Pairs of nuclei in apical cells of a common‐ B heterokaryon ( A 41 B 41 + A 2 B 41) of Schizophyllum commune fused prior to the nuclear division. It is assumed that each fusion was followed by a reduction division. Five consecutive fusions and divisions in a single hypha were photographed in situ with a phase microscope. These fusions and reduction divisions are possibly related to the genetically determined phenomenon of somatic recombination as a part of the parasexual cycle in fungi.
