Coccidinium Chatton & Biecheler, 1934
Lectotype species: Coccidinium duboscqui Chatton & Biecheler
Taxonomic status: currently recognized as a distinct genus.
Description: Parasites of the nucleus or cytoplasm of dinoflagellates. First stages of trophonts uninucleate, with large nucleus, about 4-5 chromosomes. Cell covering without typical dinoflagellate amphiesma. Apparently without mitochondria. Trophont enlarges by feeding - depending on the species - on chromosomes or cytoplasm of the host. Parasite becomes polyenergid by nuclear division not followed by cytoplasmic division. Nuclei are located at the periphery of the parasite. Finally macro- and microspores form corresponding to gametes which fuse. Zygotes form a hyaline cyst. Currently classified in the Coccidiniales but according to Cachon and Cachon (1987), may be closer to Syndiniales than to Duscquella Chatton.

Numbers of names and species: There are 4 species names in the database at present, of which 4 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
