Taxonomic status: currently recognized as a distinct genus.

Most recent taxonomic treatment adopted: Yoon, H.S., Nelson, W., Lindstrom, S.C., Boo, S.M., Pueschel, C., Qiu, H. & Bhattacharya, D. (2016). Rhodophyta. In: Handbook of the Protists.

Taxonomic notes
According to Yoon et al. (2016: [31]) and most previous authors, "The class Bangiophyceae includes one order Bangiales, one family Bangiaceae, and 12 currently recognized genera with ca. 130 species." By contrast, Athansiadis (2016: 38) refers all these genera, except Bangia which remains in the Bangiaceae, Bangiales, to the Porphyraceae, which he refers to the Porphyrales. - (6 Feb 2017) - M.D. Guiry

Description: Gametophytic frond membranous; lanceolate, linear-lanceolate, linear, laciniate, orbiculate, ovate; mainly epilithic, occasionally epizoic, rarely epiphytic; frond color variable (pink, brown, purple, grey, red, olive green and thereof); usually few cm to one meter in length; monostromatic; 21.5–140 µm thick; vegetative cells containing one stellate plastid, rarely two; sexual thalli: (i) dioecious, (ii) monoecious and divided into male and female sectors by a vertical line, (iii) monoecioius with group of cells forming either spermatangia or zygotosporangia in streaks or patches, (iv) rarely monoecious with spermatangia and zygotosporangia intermixed in the fertile region of the thalli; occurring in the upper, mid, lower intertidal, or shallow subtidal in winter, spring, summer, or autumn. Distinguished from other bladed Bangiales by rbcL and 18S gene sequence differences.

Numbers of names and species: There are 80 species names in the database at present, as well as 4 infraspecific names. Of the species names, 41 have been flagged as accepted taxonomically on the basis of the listed literature under the species name. In some instances, opinions on taxonomic validity differ from author to author and users are encouraged to form their own opinion. AlgaeBase is a work in progress and should not be regarded as a definitive source only as a guide to the literature..

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
