Description: Cells in 4-8-16- celled colonies within markedly expanded mother cell walls and with hyaline mucilage envelope. Cells fusiform, oval or cylindrical but seldom symmetrically so, mostly slightly reniform, the apices rounded-acuminate to broadly rounded and not thickened, 6-38 x 2-14 &m. Cell wall smooth. Chloroplast single, parietal with one pyrenoid. Asexual reproduction by (2)-4-8 autospores released by mucilaginization and rupture of the expanded mother cell wall. Sexual reproduction and flagellated stages unknown. Nephrocytium, planktonic, probably cosmopolitan in freshwater habitats. Similar to Nephrochlamys but possessing a pyrenoid and to Juranyiella but lacking cell wall granulations

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
