Description: Thallus unicellular (Oltmannsiellopsis unicellularis) or colonial (O. geminata and O. viridis); colonies composed of two or four cells; cells ovoid or ellipsoid, without a cell wall, quadriflagellate with flagella emerging from an anterior depression. Cells in colonies arranged in linear series with lateral margins closely appressed. Cells with a single cup-shaped chloroplast containing a distinct pyrenoid. Pyrenoid traversed by thylakoids and surrounded by several starch bodies. Cells with a large stigma, anterior or posterior. Nucleus associated with several light refractive granules, which are also present elsewhere in the cell. Asexual reproduction through longitudinal cell division. Sexual reproduction is unknown.

Numbers of names and species: There are 3 species names in the database at present, of which 3 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.

Verification of data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
