| Type species: Entophysalis granulosa Kützing 1843 | ||||||||||
| Descriptions: Komárek & Anagnostidis (1998):Colonies gelatinous, irregular, granular, microscopic to macroscopic and covering the substrate, sometimes (especially when young) polarized, attached to the substrate, later composed of subcolonies forming aggregates, which are sometimes radially or serially disposed within the thallus. Cells or their groups disposed in colonies more or less in radial or erect rows, enveloped by their own, usually layered and distinct,. delimited mucilaginous envelopes; cells spherical to irregular, often of variable size in a colony, with pale blue-green, olive-green or yellowish, finely granular content. Komárek (1992): Unicellular - colonial; colonies gelatinous, irregular, granular, microscopic up to macroscopic and covering the substrate, composed from agglomerated subcolonies, which are sometimes radially disposed within the thallus. Cells or their groups disposed in colonies more or less in radial or erected rows, enveloped by their own, usually layered mucilaginous envelopes; cells spherical up to irregular, in one colony often of different size, with pale blue-green, olive-green or yellowish, finely granular content. Geitler (1932): Zellen mit weiten, blasigen, ineinandergeschachtelten Membranhüllen; Zellen bzw. Zellgruppen in aufrechten Reihen angeordnet, weit ausgebreitete, krustige Lager bildend. Dauerzellen. |

| Reproduction strategies, life cycles, cell division: Komárek & Anagnostidis (1998): Cells divide in three or more planes in successive generations and reach approximately the original size before the next division. The rows of cells originate probably by the prevalence of cell division in one plane. Reproduction mainly by small colonies or gelatinous groups of cells. Komárek (1992):Cells divide in three or more planes in successive generations and grow more or less into the original size before the next division. The rows of cells arise probably by the prevailing cell division in one plane. Reproduction mainly by small colonies or groups of cells. |

| Taxonomic position, higher hierarchy: Cyanophyceae, Chroococcales, Entophysalidaceae, Entophysalidoideae Notes to taxonomy, misinterpretations: Described about 20 species, several unclear; probably more species exist. |
||||||||||
| Ecology, ecophysiology, ecological significance: Komárek (1992):Majority of species grows in water level or intertidal zones on rocky shores of seas allover the world and less of inland lakes, one species grows aerophytically on wet serpentine rocks in the central Europe. |
