Diagnosis:
Type species:Crinalium endophyticum Crow 1927
Descriptions:
Komárek (1992): Filamentous; filaments unbranched, irregularly waved or coiled, solitary or in microscopic clusters; trichomes without or with fine, diffluent and facultative sheaths, isopolar, more or less equally wide along the whole length or slightly narrowed to the ends, clearly and obligatory flattened from sides, on the cross section oval, uniserial, slightly constricted or unconstricted at the cross walls, immotile. Cells more or less isodiametrical or slightly shorter or longer than wide, without aerotopes, with slightly granular and blue-green content. End cells widely rounded. Heterocytes and akinetes are missing.
Genotype differences, molecular data:
Reproduction strategies, life cycles, cell division:
Komárek (1992):Cell division cross the daughter cells grow more or less into the original size before the next division. Reproduction by hormogonia, which separate from the mother trichome without help of necridic cells, but sometimes with special separating discs.
Ultrastructure:
Taxonomic position, higher hierarchy:
Cyanophyceae, Oscillatoriales, Gomontiellaceae, Gomontielloideae
Notes to taxonomy, misinterpretations:
Ecology, ecophysiology, ecological significance:
Komárek (1992):The type species grows endogloeic in the mucilage of subaerophytic Aphanocapsa (on wet rocks in England), one species known from pools in Antarctica, another from soil biotopes in the Netherlands. One species from India is unclear.
