Corisphaera Kamptner, 1936
Holotype species: Corisphaera gracilis Kamptner
Currently accepted name for the type species: Helladosphaera gracilis (Kamptner) Norris
Taxonomic status: currently recognized as a distinct genus.
Most recent taxonomic treatment adopted: Jordan, R.W., Cros, L. & Young, J.R. (2004). A revised classification scheme for living haptophytes. Micropaleontology 50(Suppl. 1): 55-79.
Comments: Following the recent observations that many holococcolithophores are phases in the life cycles of heterococcolithophores, the family Calyptrosphaeraceae is now known to be polyphyletic, so Jordan et al. (2005) recommend abandoning its use. However, until all or most holococcolith-bearing taxa can be transferred into other existing families, ithey consider it wise to keep them together. Heimdal (1997: 752) records this genus as a member of the Order Coccosphaerales, Family Calyptrosphaeraceae.
Numbers of names and species: There are 21 species names in the database at present, as well as 1 infraspecific names. Of the species names, 5 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.
