The Dictyostelium phylogeny tree has undergone multiple changes in the past decades. The first dictyostelid to be described was Dictyostelium mucoroides in 1869 by Osker Brefeld, but the original discovery of Dictyostelium Discoideum occurred in 1935. Dictyostelium Discoideum was initially classified under ‘lower fungi,’ but the classification has since shifted the classification to under the Amoebozoa phylum where it is currently. Webmyxamoebae and the life cycle begins anew. In those species with spores characterized by polar granules (PG+), myxamoebae can quickly halt development and form resistant microcysts. Even more resistant macrocysts are produced as a result of sexuality in many dictyostelids, both PG+ and PG- (spores without polar granules) species.
