General Environment
This is a freshwater species.
Description
Cells gold–colored, spherical, with a distinct wall, assembled in the periphery of macroscopical gelatinous colonies, which start as tubular or sac–like structures, but later become membranous. Cells with 1–2 parietal chloroplasts, without a stigma or pyrenoid, and reproduction occurs by longitudinal cell division.
Key Characteristics
Cells in the colonies also divide by what appears to be smaller autospores with remnant cell walls remaining, the colonial mucilage consists of cylindrical dichotomously branched tubes radiating from the center of the colony to which attach the peripheral cells, and older cells become filled with large oil droplets.
