Description: In nature, known strains grow in saline–alkaline lakes in the Brazilian Pantanal wetland. The trichomes are microscopic and, in liquid medium, they grow as free-floating trichomes that are distributed in the culture flask. The trichomes are frequently organised in ornate (interwoven) mats. Macroscopically, the culture has a reddish to brownish colour. Trichomes do not have sheaths but do have a diffluent mucilage and are non-motile. Cells are isodiametric or longer than they are wide, 1.5–4.1 µm long by 1.1–2.2 µm wide, with a narrowed or rounded-conical apical cell. Cell content is homogeneous and reddish to brownish. Hormogonium formation occurs via trichome disintegration.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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