Taxonomic status: currently recognized as a distinct genus.
Description: Cells solitary or in 4-celled colonies within the mother cell wall. Mucilage envelope lacking. Cells lunate, slightly twisted with broadly rounded to slightly acuminate apices, 3.5-10-(12) x 1-4 µm; colonies 11-20 µm in length. Cells uninucleate; chloroplast single and parietal, without a pyrenoid. Asexual reproduction by (2)-4-(8) autospores which may be retained within the mother cell wall, the latter becoming expanded but retaining the shape of the vegetative cell. Sexual reproduction and flagellated stages unknown. Chiefly distinguished from the closely related Nephrocytium by the absence of a pyrenoid and from Juranyiella by the absence of granulations on the cell wall. Nephrochlamys, planktonic, widely distributed in freshwater in Europe, Japan, North and Central America.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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