Nomenclatural notes
Silva & Lipkin (2003: 380) note that "'Algues', pl. 2, fig. 3 (Fig. 7) was considered by Audouin (1826b, p. 249: 1828b, p. 86) to be a previously undescribed species of Digenea, which he named D. dichotoma, In fact, the illustrations in Savigny's Ag. 3 look exactly like thoroughly washed Galaxaura mgosa (Ellis et Solander) Lamouroux, a species that almost always is heavily silted in the field and thus does not resemble Savigny's figure. The illustrated details of the thin lateral branches also agree with those of G. rugosa." - (3 Jul 2017) - M.D. Guiry
