Holotype species: Catenococcus tortuosus Hindák
Original publication:Hindák, F. (1977). Studies on the chlorococcal algae (Chlorophyceae). I. Biologicke Práce 23: 1-192.
Taxonomic status: currently recognized as a distinct genus.
Description: Colonial thalli with irregular outlines to 100 &m diameter, with 4-24 cells embedded in large mucilage sheath. Cells arranged in uniseriate, unbranched chains; in larger thalli chains s-shaped or spirally twisted. Cells spherical, 1.2-2.8 &m or 3-8 &m diameter, closely adjoining in structureless mucilage; cell walls without obvious ornamentation. Cells uninucleate with single, cup-shaped, parietal chloroplast; pyrenoid present or absent. Asexual reproduction by autospores, 3-4 &m diameter (in large celled species), with 2-8 (usually 4) spores per sporangium; spores released by dissolution of cell wall. Flagellated stages absent. Sexual reproduction unknown. Catenococcus planktonic, known only from Czecholovakia in eutrophic lakes and rivers. Species distinguished on cell size, and presence/absence of pyrenoid. Genus originally assigned to Hormotilaceae, currently in subfamily Palmodictyoideae of Radiococcaceae with Dactylothece and Palmodictyon.

Numbers of names and species: There are 2 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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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