Holotype species: Collodictyon triciliatum H.J.Carter
Original publication and holotype designation:Carter, H.J. (1865). On the fresh- and salt-water Rhizopoda of England and India. Annals and Magazine of Natural History ser. 3, 15: 277-293.
Taxonomic status: currently recognized as a distinct genus.
Description: Unicellular,uninucleate and quadriflagellate algae devoid of cellulosic cell walls.Cell shape variable but mostly obovoid to ellipsoid. Lateral marginssomewhat angular with a broad, truncately-rounded apex, narrowing to the posteriorwhich may bear 1-3 lobes or be simply broadly rounded. Cell posterioroften pseudopodial. Nucleus typically posterior. Cells withoutchloroplasts and stigmata. Cytoplasm heavily vacuolate with two toseveral contractile vacuoles.Asexualreproduction by cell division; sexual reproduction unknown.Unicellular,uninucleate and quadriflagellate algae devoid of cellulosic cell walls.Cell shape variable but mostly obovoid to ellipsoid.

Comments: Collodictyon> has two well described species, C. tricellatumCarter and C. sparsevacuolatum Skuja reported from freshwatewr in Europeand the United States. C. hongkongense Skvortzow is inadequatelydescribed. The assignment of the marine C. sphaericum Norris to Collodictyonwas questioned by Ettl

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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.
