''Linea'' is a genus of foraminifera belonging to the subfamily Rhabdammininae. It is a monotypic genus containing the sole species ''Linea simplex''. Morphology ''Linea simplex'' has an overall string-like appearance, with a thin unbranching test in the shape of a flexible tube with a consistent diameter of around 80 μm. The tube is several centimeters long, irregularly filled by dark material, presumably stercomata. It is morphologically similar to '' Dendrophrya'' except it is unbranched. It also has similarities with '' Bathysiphon'' but is smaller in diameter and has a much thinner wall section. Taxonomy The genus and species were described in 1989 by C. J. Schröder, F. S.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
