Taxonomic notes
Wynne & Heine (1992: 70) cite an abstract by G. Hansen proposing that Euthora be reinstated as a genus distinct from Callophyllis on ther basis of the uniaxial organisation and monoecious conditon of Euthora in contrast to the multiaxial organisation and dioecious condition of Callophyllis. See Hooper & South (1974).

General environment
This is a marine species.
