Abstract
The nucleoli of Oudemansiella mucida and Nolanea cetrata become disassociated from the parent chromatin during both mitosis and meiosis. Disassociation of the nucleoli from the post-meiotic nuclei at the onset of migration is taken, along with other evidence, to indicate that the third nuclear division is initiated in the basidium and completed in the basidiospores. It is postulated that the coincidence of migration and the third nuclear division arises from the inability of nucleoli to pass through the sterigmata. This view is supported by observations made by the authors on other members of the Homobasidiomycetidae.Keywords
