Colpomenia

Colpomenia is a genus of brown macroalgae (or seaweed) in the family Scytosiphonaceae.

== Taxonomy and Nomenclature == Colpomenia is currently composed of 11 confirmed species with Colpomenia sinuosa as its type species. Earlier taxonomic placements of the members of this genus have been problematic starting from the ambiguous morphological delineation up until the discovery of the polyphyly within the genus using molecular data. Two significant taxonomic revisions have been started to clarify the polyphyly within the genus. First, was the transfer of all previous members of Colpomenia with erect, finger-like thalli into the new genus Dactylosiphon based on morphoanatomical, molecular, and life history observations. Second, was the formal separation of Colpomenia tuberculata (now Encephalophycus tuberculatus) from the rest of the genus due to the stark differences in its morphology molecular phylogeny.
