'''''Tetramyxa''''' is a cercozoan protist, member of the plasmodiophores, parasite of several flowering plants.<ref name="StraminipilousFungi"/> It was first described by Karl von Goebel in 1884, in his work ''Flora''.<ref name="Tetramyxaparasitica"/> The genus is characterized by the appearance of resting spores (or cysts) in groups of four.<ref name="Tetramyxaparasiticaultra"/>
==Taxonomy== There are two accepted species:<ref name="StraminipilousFungi"/><ref name="WoRMS172135"/> *''Tetramyxa parasitica'' {{au|K. Goebel, 1884}} (=''Thecaphora ruppiae'' {{au|W. A. Setchell, 1924}}) – parasite of ''Zannichellia'', ''Potamogeton'' and ''Ruppia'' roots. *''Tetramyxa marina'' {{au|Y. Lipkin & A. Avidor, 1974}} – parasite of ''Halophila stipulacea'' petioles. The following additional species, though recognized as ''Tetramyxa'', are listed as doubtful in some sources:<ref name="StraminipilousFungi"/> *''Tetramyxa rhizophaga'' {{au|D. Lihnell, 1942}} – parasite of ''Juniperus communis'' roots. *''Tetramyxa triglochinis'' {{au|M. Molliard, 1909}} (=''Molliardia triglochinis'' {{au|(M. Molliard) R. Maire & A.
