Holotype species: Phyllocardium complanatum Korshikov

Taxonomic status: currently recognized as a distinct genus.

Description: Unicellular,biflagellate and uninucleate alga without cellulosic cell walls. In broadfront view, cells 9-12 um wide and 11-19 um long, broadly pyriform; anteriorend broadly rounded with a distinct conical papilla from which flagella arise.Lateral margins broadly convex, narrowing posteriorly to an extended hyalinecaudus. Cells rather strongly compressed such that in narrow side view,cells elliptic to swollen-fusiform. Flagella about twice as long as cell.Chloroplast parietal and principally cup-shaped, but may not completelyencircle cell lumen; in latter case free margins of chloroplast may be slightlyemarginate. Stigma large and usually median, pyrenoids absent.Nucleus in lumen of chloroplast, approximately median in position. Asexualreproduction by longitudinal binary division. Sexual reproductionanisogamous, gametes similar to vegetative cells except that they are notcompressed. Details of post-zygotic development unknown.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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