Request PDFFossil: This is a genus of fossil species, or a genus with a fossil type species, or a genus the type species of which was originally described as a fossil.
Description: Thallus club-shaped and worm-like calcified unbranched unicell 1-2.5 cm tall with an apical tuft of hairs. Calcification ring-like, segmented bands. Axis bearing densely packed whorls of 30-40 laterals each branched to the third degree. First degree branches free (N. van Bosseae) or coherent (N. dumetosa). Secondary laterals modified to one uninucleate gametangium and two swollen photosynthetic units that form a faceted surface barely protruding beyond the calcification at the surface. Each gametangium forms a single cyst which after multiple divisions form biflagellate gametes which are liberated after the opening of a structured operculum. Parietal chloroplasts numerous and discoid without pyrenoids; starch grains both inside and outside plastid, the latter not membrane bound. Neomeris cosmopolitan in tropical and subtropical seas. From shallows to 30 m; firmly attached to solid substrate. Often the only macrophyte in a heavy current or eroded area. Known from fossil record to the Cretaceous.

Contributors
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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.
