Genus novum et species nova ex ordine Protococcales. Novitates Systematicae Plantarum Non Vascularium 3: 60-62, 1 pl., 17 figs.

Description: Solitary or more commonly colonial groups up to 16 cells without conspicuous mucilaginous envelope. Cells distincly flattened, 13-16.5 x 9.5-13 x 3-3.3 µm. In face view cells oval to ellipsoidal, in side view fusiform with rounded ends. Cells uninucleate; single chloroplast parietal and band shaped with conspicuous central pyrenoid. Asexual reproduction by autospore formation and colony fragmentation; 4 (-8) spores per sporangium. Spores released by dissolution of sporangial wall. Flagellated stages and sexual reproduction unknown. Coenolamellus planktonic in brackish water; found only in Caspian Sea in salinity of 3.6 0/00. Coenolamellus similar to Chlorolobion, Choricystis and Selenoderma from which it differs based on cell shape, number of autospores, absence of mucilage and presence of a pyrenoid. Genus poorly known and requires further study. Key ref: *Proskina-Lavrenko (1966), Proskina-Lavrenko and Makarova (1968), *Komárek and Fott (1983), Marvan and others (1984).

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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