Diagnosis:
Type species: Chroococcidium gelatinosum Geitler 1933.
Descriptions:
Komárek (1992): Unicellular - colonial; small agglomerations of cells, irregularly localized in fine, diffluent, colourless, sometimes slightly lamellated mucilaginous envelopes; colonies microscopic, but sometimes form macroscopically visible gelatinous masses. Cells spherical, hemispherical, irregular spherical, oval, more or less rounded, usually of different size in one colony, rarely irregular, blue-green; usually without own mucilaginous envelopes.
Genotype differences, molecular data:
Reproduction strategies, life cycles, cell division:
Komárek (1992): Cell division irregularly in more pmnes in successive generations, sometimes without growing into the original size and shape. Daughter cells within one group (from one mother cell) are often of different size. Another type of cell division: from large cells arise sometimes 8-16(32) nanocytes.

Taxonomic position, higher hierarchy:
Cyanophyceae, Chroococcales, Xenococcaceae
Notes to taxonomy, misinterpretations:
Ecology, ecophysiology, ecological significance:
Komárek (1992):The type species was described from periphyton on water plants in one lake in Indonesia (Sumatra); not revised, no other known species.
