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. [6] 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. [4]
The genus is placed in the family Protosteliidae within the monotypic order Protosteliida, which is part of a larger group of amoebozoans known as Variosea. [1] [7]
Many species from the genus Protostelium have been transferred over time to other protosteloid genera. The following species remain: [4]
