Umbilicosphaera sp.


Classification: ntax_cenozoic -> Coccolithales -> Calcidiscaceae -> Umbilicosphaera -> Umbilicosphaera sp.
Sister taxa: U. anulus, U. foliosa, U. hulburtiana, U. sibogae ⟩⟨ U. jafari, U. rotula ⟩⟨ U. bramlettei, U. jordanii, U. protoannulus ⟩⟨ U. detecta, U. edgariae, U. henrikseniae, U. sp.

Taxonomy:

Citation: Umbilicosphaera sp.
taxonomic rank: generic level id
Synonyms: Cycloplacolithella simplex Haq (1968) = Calcidiscus simplex (Haq 1968) - this comibnation was used by Perch-Nielsen 10985 but without an indication of who proposed it. The type of C . simplex is very poor but if it is intereted as a Cacidiscaceae then it would fall in Umbilicosphaera as used here.

Distinguishing features:
Parent taxon (Umbilicosphaera): Central area open
This taxon: Specimens which cannot be assigned to established species

Farinacci & Howe catalog pages: C. simplex *


Cultures: Strains of this species are maintained in culture, for details see Roscoff Culture Collection.
