Request PDFDescription: Unicellular-colonial; initial cells spherical, later hemispherical to irregularly rounded-conical, packed into colonies; colonies in a form of 2-16-celled to multicelled packet-like aggregates with tightly, radially and "fan-1ike" oriented cells (with the "conical" part oriented into the center of a colony), enveloped by a thin, colorless, usually firm, tight and sometimes slightly structured (lamellated) gelatinous envelope (the outer layers of which in several species become gelatinous and diffluent). Cells blue-green, pale greyish blue-green or yellowish and olive-green, sometimes with several prominent granules in plasma or with finely granular content. Division of cells in 3 perpendicular planes in successive generations in the beginning, later divide more or less radially in the colony, without the divided cells having grown into the original spherical shape, but growing more or less into the original size. Multiplication by the dissociation of colonies. One of the 4 described species, is known from the subaerophytic localities in calcareous rocks (Europe), one from tropical soils, one from halophilic swamps, and one from the plankton of Caspian sea. Probably more species distributed, but overlooked or misinterpreted with other cyanophytes (Chroococcus, Myxosarcina, Gloeocapsa, etc.).

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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.
