Nomenclatural notes
Silva & Nelson (2008) concluded that "Silva's choice of Conferva fuscopurpurea Dillwyn as generitype must be rejected in favor of Pfeiffer's previous choice of C. atropurpurea Mert. ex Roth. Bangiadulcis W.A. Nelson, based on C. atropurpurea, is thus rendered a superfluous name for Bangia Lyngb. The latter name when properly typified applies to a genus that currently comprises a single freshwater species. Generic limits remain to be established among the phylogenetically diverse marine populations currently assigned to Bangia." See also Sutherland et al. (2011: 1138). - (7 Feb 2012) - M.D. Guiry

Description: Filamentous, unbranched, attached by rhizoidal outgrowths from cells at base of filament; n = 3 with one chromosome shorter than other 2 (ca. 0.5 ┬Ám found in freshwater; forming band at or above the waterline; only asexual populations known, producing archeospores.

Information kindly contributed by M.D. Guiry from original description but may now be outdated.

Comments: GenBank Accession number nSSU rDNA= AF169341; rbcL = AF169330. Freshwater populations generally form a discrete band 5-15 cm wide, at or above the waterline in alkaline waters (pH 7.8-8.5 and specific conductance 170-320 &S cm-1). Populations in Lake Michigan (USA) have high internal concentrations of bromine and zinc. Freshwater grazing is minimal. Bangia is opportunistic, having small thalli with rapid growth and high reproductive output (r-selection).

Numbers of names and species: There is only one species or infraspecific name in the database at present.

Names: ('C' indicates a name that is accepted taxonomically; 'S' a homotypic or heterotypic synonym; 'U' indicates a name of uncertain taxonomic status, but which has been subjected to some verification nomenclaturally; 'P' indicates a preliminary AlgaeBase entry that has not been subjected to any kind of verification.

Contributors
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in CD format. These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above. The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.

Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
