Holotype species: Ettliella tetraspora F.Hindák
Taxonomic status: currently recognized as a distinct genus.
Description: Thalli oval to spherical colonies, 20-30 µm diameter, comprised on 2-4-8-16 cells in structureless mucilaginous envelope. Cells oval, 6.5-10 x 1-6 µm, generally arranged in tetrads with cells in parallel and empty space in center in polar view. Cell walls smooth. Cells uninucleate; chloroplast single and parietal with one pyrenoid. Asexual reproduction by autospores, 2 or mostly 4 per sporangium; released by gelatinization of expanded mother cell walls. Flagellated cells and sexual reproduction unknown. Ettliella planktonic in freshwater, known only from fishpond and lake in Moravia and Finland. Genus distinguished by cell shape and arrangement, and mechanism of spore release.

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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