Phalansterium is a genus of single-celled flagellated organisms comprising several species, which form colonies.[1] Phalansterium produces tetraspores.[2]

Phalansterium is hard to classify; it has a distinctive ultrastructure of its pericentriolar material. Molecular evidence places it in the Amoebozoa.[3][4]

It has been suggested that it is similar to the ancestral eukaryote.[5]
