Adrianema

Generic name: ADRIANEMA De Toni, 1936. Noter. Nomencl. Algol. 8: 2.,Cyanophyceae, Stigonematales, Mastigocladaceae, Brachytrichioideae

Synonyms: LITHONEMA Ercegović, 1929. Ann. Protist. 2: 136.

Diagnosis:

Type species: Adrianema adriaticum ( Ercegović) De Toni 1936

Descriptions:
Komárek (1992):Thallic, branched filaments; thallus irregular, flattened, endolithic, composed from free, irregularly disposed, tangled, branched filaments. Filaments unsheathed, but with wide, fine, colourless, difluent, sametime slightly visible, rarely brownish and limited mucilaginous envelopes. Trichomes uniserial, irregularly waved , more o less cylindrical or with slightly irregularly swollen cells, at the ends sametimes slightly widened, not constricted or constricted at cross walls; types of the true branching: T- type, pseudodichotomous V- type, reverse Y- type; trichomes sometimes irregularly barrelshaped, isodiametric or longer than wide, end cell rounded; cell content blue- green, homogeneous. Heterocytes and akinetes not known.

Genotype differences, molecular data:

Reproduction strategies, life cycles, cell division:
Komárek (1992): Cell division cross- wise, perpendiculary to the trichome axis. Reproduction propably by the fragmentation of trichomes, but the propagation is not know.

Ultrastructure:

Taxonomic position, higher hierarchy: Nostocophycideae, Nostocales, Symphyonemataceae
Notes to taxonomy, misinterpretations:

Ecology, ecophysiology, ecological significance:

Komárek (1992):The single species is know from calcareous rocks of the tide zone of the Adriatic Sea coast (Dalmatia). A little know genus.
