Diagnosis:
Type species:Cyanodermatium gelatinosum Geitler 1933.
Descriptions:
Komárek (1992): Unicellular - colonial; mats on substrate, wide, thin, crustaceous, microscopic or macroscopic, composed from erected, parallel, pseudodichotomously or pseudotetrachotomously divaricated, short pseudofilaments, which are oriented more or less perpendicularly to the substrate; pswdofilaments enveloped by firm sheaths and are joined tightly together or confluent by their sides; from above they look as pseudoparenchymatous layer. Cells irregular, sometimes slightly elongated in the direction of pseudofilaments.
Genotype differences, molecular data:
Reproduction strategies, life cycles, cell division:
Komárek (1992):Cell division (binary fission) irregular, in more planes in successive generations, but in pseudofilaments prevails the crosswise division to the pseudofilaments. Nanocytes not observed. Reproduction probably by the clusters of several cells.
Ultrastructure:
Taxonomic position, higher hierarchy:
Cyanophyceae, Chroococcales, Hydrococcaceae
Notes to taxonomy, misinterpretations:Two species, very little known.
Ecology, ecophysiology, ecological significance:
Komárek (1992):Both species epilithic, described from stones in the littoral zone of lakes in Sumatra (Indonesia).
Physiology and biochemistry:
Distribution, endemism, problematic
