Original descriptions of taxa. For coccolithophores, and many calcispheres, these are pages from the Farinacci & Howe Catalog of Calcareous Nannofossils. In other cases (e.g. non-calcifying haptophytes) the data is directly compiled on this site. The "Catalogue of Calcareous Nannofossils" was originally compiled by Prof A. Farinacci 1969-1989, since 2000 it has been updated and extended by Richard Howe - see The Farinacci and Howe Catalog - an Introduction.
Taxa are sorted alphabetically for simple browsing, or you can use search boxes at the top & bottom of the page

Original Description Cells solitary, motile, 3-7.5 µm in diameter, metabolic, covered by several layers of scales with superficial pattern of around 40 radial ridges. Flagella two, equal (around 7 µm) inserted apically with abbreviated haptonema (100 nm) between with three to four microtubules in emergent part and bearing small oval scales with central swelling and around 12 radial ridges. Plastid single, parietal, yellow-brown with immersed pyrenoid. Asexual reproduction by division in motile and non-motile stages. Non-motile cells embedded in thin layer of mucilage Size: Cells 3-7.5 µm in diameter Etymology: lutea refers to the orange colour of cells, particularly noticeable in old cultures of the species Extra details from original publication Strain isolated by Haines in 1977 from Tahiti (tropical Pacific Ocean). Codes applied to the type strain iniclude: AC102, T.ISO, HAP34T, CCAP927/14, CCMP1324, NEPCC 601, CS-177 Editors' Notes Was informally refered to as T-Iso
