Description: In nature, growing on the bark of trees, wood, or concrete. Thallus microscopic in nature and in culture. In culture primarily growing attached to the glass walls of the test tubes in liquid media, and released as tufts which detach and settle to the bottom of the test tube as they grow, on agar growing radially from the center via hormogonia release, forming a dense creeping mat. Colonies spherical when developing from akinetes, elongate when developing from hormogonia, eventually aggregated loosely into macroscopic thalli through release of diffluent mucilage. Akinetes apoheterocytic, spherical or subspherical, granulated, developing from vegetative cells in trichomes, germinating into two equal vegetative cells or alternatively into a large vegetative cell and a smaller heterocyte, either of which develops into spherical colonies with a firm mucilage layer, which eventually become larger colonies enclosed within a diffluent mucilage. Hormogonia developing from older more diffuse colonies; when first formed motile, short, lacking firm mucilage, later immotile with heterocytes and akinetes, developing into multiseriate filaments, which eventually become elongate colonies enclosed in a firm mucilage. Cells quadratic in young hormogonia, becoming spherical or subspherical as filament matures, dividing perpendicular or longitudinal to the main axis of filament. Heterocytes spherical, compressed subspherical or oval.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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