Holotype species: Rhodella maculata L.V.Evans

Original publication and holotype designation: Evans, L.V. (1970). Electron microscopical observations on a new red algal unicell, Rhodella maculata gen. nov., sp. nov. British Phycological Journal 5: 1-13.

Taxonomic status: currently recognized as a distinct genus.

Most recent taxonomic treatment adopted: Athanasiadis, A. (2016). Phycologia Europaea Rhodophyta Vol. I. pp. [i]-xxxxviii, 1-762. Thessaloniki: Published and distributed by the author.

Description: Unicellular, planktonic, typically spherical, lacking a cell wall, but surrounded by a thick mucilage layer. Has a single, large, lobed, parietal chloroplast with central pyrenoid. Thylakoids do not penetrate the pyrenoid. Contains B-Type II phycoerythrin. Nucleus in close contact with the pyrenoid through protrusions which penetrate into membrane-lined channels in the pyrenoid. Asexual reproduction by binary fission. Sexual reproduction unknown.

Numbers of names and species: There are 6 species names in the database at present, of which 1 has 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
