Description: In nature, known strains grow in saline–alkaline water in the Brazilian Pantanal wetland. The trichomes are microscopic and, in liquid medium, they grow as olive-green colonies attached to the tube walls. Filaments are entangled and flexuous. The cells are slightly constricted, and the cross wall is quite translucent. The sheath is hyaline, firm, attached to the trichome and always present. Cells are isodiametric or wider than they are long, 1.2–3.1 µm long by 1.5–3.1 µm wide. The apical cell is cylindrical with a rounded apex. Cell content is homogeneous and brownish green or olive green. 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
