While most biologists are familiar with nuclei that have a single, central, more or
less spherical nucleolus, there are many variations on this theme. Several of these
permutations are found in the various amoebae of eumycetozoans. These differences in
nucleolar morphology may have some phylogenetic significance, but are clearly useful in
helping researchers to identify the taxa in which they occur. Using a combination of
microscopy techniques, we illustrate the typical nucleoli found in myxomycetes, most
protostelids, dictyostelids, and the protostelids Soliformovum spp. and Echinosteliopsis
oligospora. We emphasize the previously unpublished details of E. oligospora.
