Goniodoma F.Stein, 1883, nom. rejic.
Holotype species: Goniodoma acuminatum (Ehrenberg) F.Stein
Currently accepted name for the type species: Scrippsiella acuminata (Ehrenberg) Kretschmann, Elbrächter, Zinssmeister, S.Soehner, Kirsch, Kusber & Gottschling
Original publication and holotype designation: Stein, F. (1883). Die naturgeschichte der arthrodelen Flagellaten. In: Der Organismus der Infusionstiere. III. Pt. 2. ( Eds), pp. 1-30. Leipzig:
Taxonomic status: currently regarded as a synonym of Scrippsiella.
Gender: This genus name is currently treated as neuter.
Most recent taxonomic treatment adopted: Steidinger, K.A. & Tangen, K. (1996). Dinoflagellates. In: Identifying Marine Phytoplankton. (Tomas, C.R. Eds), pp. 387-584. San Diego: Academic Press.
Description: Medium-size (30-95 µm) biflagellated cell, polyhedric to subspherical shaped, with a more or less median but slightly displaced cingulum; sulcus restricted to the hypocone. Cell wall of cellulosic plates, the plate borderlines as well as the cingulum sometimes crested. Plates may bear a heavy reticulation and have pores. Plate formula: Po, 3',7", 6c, 7s, 6'",2"", but this has been interpreted differently by various authors. The apical pore platelet has a typical hook- shaped pore, the first apical plate does not reach the cingulum. These characters are shared with species in the genera Pyrodinium and Alexandrium; therefore, several species of Alexandrium have been described as or transferred to Goniodoma. Cells with numerous chloroplasts, nucleus horseshoe-shaped. Reproduces by binary fission during motility; both daughter cells share the thecal plates of the mother cell, and the theca is split along a special fission line. The overlap pattern of the plates reflect this fission line. Sexual reproductiohn no reported. Bioluminescence has been reported, but there is no indication that species of this genus are toxic in contrast to those of the genera Alexandrium or Pyrodinium. Marine plankton, restricted to warm waters.

Numbers of names and species: There are 18 species names in the database at present, as well as 1 infraspecific names. Of the species names, 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.
