. Electron microscope observations of the trophic and cyst stages of the protostelid Protostelium pyriformis Olive & Stoianovitch, 1969 indicate a perinuclear golgi‐vesicular region in the amoeboid cell. Within this region is a microtubule organizing center (MTOC) and associated microtubules which radiate into the cytoplasm. The cyst wall is revealed as having three distinct regions, certain areas of the wall possibly corresponding to exit pores. Protostelium pyriformis shares many similarities in trophic cell structure with other eumycetozoans and members of the non‐mycetozoan family Acanthamoebidae.
