Description: Cells generally ovoid, firmly attached on the substrate by their narrow ends. Cell wall thin, smooth, covered by a mucilaginous layer. Cells solitary or grouped into dense colonies covering the major part of the substrate. The cells often form hemispherical or clumpy accumulations composed of two or four cells. Cell apex is usually rounded, but can be clearly pointed. In that case, the pointed end faces inwards the colonies. Chloroplast cup-shaped, placed at distal part of the cell, containing a distinct pyrenoid. Nucleus located in the cell centre. Asexual reproduction by production 2–4(–8) zoospores or 2–4 autospores per cell. Zoospores quadriflagellate, ovoid to pyriform, with a cup-shaped chloroplast, contractile vacuoles, and stigma. A genus of two described species from freshwater habitats.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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