Summary

A parasexual cycle analogous to that of Aspergillus nidulans takes place in the Basidiomycete Coprinus radiatus. Methods which allow the isolation of diploid strains are described. The stability of these strains has been studied. The diploid return to an haploid state through successive and random loss of one chromosome of each pair of homologues; however, the frequency of haploid and aneuploid nuclei does not increase with the age of some diploid strains. This means that, in a diploid context, the diploid state is under some control.

Evidence is presented for the existence of recombination between compatible nuclei which involves only one chromosome, and the mecanism for this is dicussed.
