Taxonomic status: currently recognized as a distinct genus.

Gender: This genus name is currently treated as feminine.

Most recent taxonomic treatment adopted: Yang, L.-E., Deng, Y.-Y., Xu, G.-P., Russel, S., Lu, Q.-Q. & Brodie, J. (2020). Redefining Pyropia (Bangiales, Rhodophyta): four new genera, resurrection of Porphyrella and description of Calidia pseudolobata sp. nov. from China. Journal of Phycology 56(4): [1-18] 862-879, 4 figs.

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, with one to several lanceolate or orbicular blades growing from a discoid or a conical holdfast, epiphytic; frond deep red or purplish in color; typically 2-7 cm long and 1-3 cm wide but can be up to 13 cm long and 6 cm wide; monostromatic, 25-35 ┬Ám thick; each vegetative cell containing a single stellate plastid; monoecious, spermatangia grouped in small scattered irregular patches near the thallus margin. Distinguished from other genera by rbcL and 18S gene sequence differences.

Numbers of names and species: There are 2 species names in the database at present, of which 2 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
