'''''Protostelium''''' is a genus of protosteloid amoebozoans, i.e., amoebae capable of forming simple fruiting bodies composed of a stalk and a ball of spores.<ref name="Olive-1975">{{cite book|first1=Lindsay S.|last1=Olive|title=The Mycetozoans|isbn=978-0-12-526250-7|doi=10.1016/B978-0-12-526250-7.X5001-7|date=1975|publisher=Academic Press}}</ref> It contains numerous species, including ''P. aurantium'', which was initially classified in a different genus '''''Planoprotostelium'''''. Phylogenetic analyses revealed that ''Planoprotostelium'' branches from within the genus ''Protostelium'', making them synonyms.<ref name="Shadwick-2017">{{cite journal|last1=Shadwick|first1=John D.
