Description: Small unicellular (10-15 µm) dinophyte with longitudinal and transverse flagella, the latter lying in the sulcus, which separates the small epicone from the much larger hypocone. From the hypocone below the cingulum, pseudopods emerge, enabling Filopodium to creep on its host, Appendicularia, thus being epiphytic (phoretic). Cytoplasm filled with numerous chloroplasts. Spherical nucleus shows ca. 20 permanently condensed chromosomes. Reproduction by multiple division. So far only reported by the authors from Appendicularia, Oikopleura dioica, from the Mediterranean Sea, classified as phoretic, but resembles somewhat some parasitic species of the Blastodiniales.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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