Tetramyxa is a cercozoan protist, member of the plasmodiophores, parasite of several flowering plants.^[2] It was first described by Karl von Goebel in 1884, in his work Flora.^[1] The genus is characterized by the appearance of resting spores (or cysts) in groups of four.^[3]

Taxonomy

There are two accepted species:^[2][4]

• Tetramyxa parasitica K. Goebel, 1884 (=Thecaphora ruppiae W. A. Setchell, 1924) – parasite of Zannichellia, Potamogeton and Ruppia roots.
• Tetramyxa marina 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:^[2]

• Tetramyxa rhizophaga D. Lihnell, 1942 – parasite of Juniperus communis roots.
• Tetramyxa triglochinis M. Molliard, 1909 (=Molliardia triglochinis (M. Molliard) R. Maire & A. Tison, 1911) – parasite of Triglochin maritimum stems, ovaries and stamens.
• Tetramyxa elaeagni Y. Yendo & K. Takase, 1932 – parasite of Elaeagnus multiflora roots.
