Nomenclatural notes
Two species were included in the protologue: N. bacillaris Naumann and N. coccoides Naumann, and a type has not been selected. - (14 Nov 2006) - Wendy Guiry

ING says that this genus name was published on 14 Feb 1921, but the Nauman paper in which the Latin description appears says "Tryckt den 2 maj 1919 [Printed May 2, 1919]" at the end of the article. - (16 Mar 2016) - M.D. Guiry

Taxonomic notes
Trebouxiophyceae (Somogyi et al. 2011: fig.11). Darienko et al (2010: fig. 1) include Nannochloris coccoides and Marvania geminata in the Marvannia-clade of the Trebouxiophyceae. Neustupa et al. (2011: fig. 22 place N. bacillaris in the Chlorellales. - (15 Feb 2011) - Wendy Guiry

Description: Cellulce singulares. Chlorophorum unum, parietale. Membrana hyalina. Structura nulla. Area mucosa deest. Propagatio hoc tantum modo prosequitur, ut cellula pariete transversa in duas partes cequales dividitur.

Numbers of names and species: There are 7 species names in the database at present, as well as 1 infraspecific names. Of the species names, 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
