Diagnosis:
Type species: Stanieria cyanosphaera (Komárek et Hindák) Komárek et Anagnostidis 1986
Descriptions:
Komárek & Anagnostidis (1998): Cells solitary or in groups, more or less spherical, usually attached to the substrate by any side (cells are not polarized), secondarily (and in cultures) in free or attached irregular, usually microscopic aggregates. Cells in a colony of variable size, with homogeneous, pale blue-grey, blue-green, yellowish, olive-green, reddish to dark red or violet content. Sheaths (vaginae) thin, firm, mucilaginous, colourless, forming a narrow hyaline layer («wall») around solitary cells.
Komárek (1992): Solitary cells (up to 40 um in diam.) or irregular groups of cells, joined to the substrate and one to another. Cells spherical or slightly widely oval, attached to the substrate by any part of a cell wall. Around the cells firm, thin, colourless sheaths, opened in any place of the surface during reproduction. Cell content greyish blue-green or reddish, thylakoids in parallel fascicles in the peripheral layer or irregularly through the whole cell volume; always without aerotopes.
Genotype differences, molecular data:
Reproduction strategies, life cycles, cell division:
Komárek & Anagnostidis (1998): Cell division only by multiple fission, more or less simultaneously or in rapid sequence in various directions, resulting in numerous spherical, motile baeocytes (planocytes), which liberate from the split or gelatinized sheaths. Small baeocytes reach the original size (several times larger than baeocytes) before the next multiple fission. Reproduction only by baeocytes.
Komárek (1992): Reproduction by the almost spontaneous total cell division (multiple fission) into many small daughter cells (nanocytes); nanocytes are motile (planocytes), and escape from the firm, layered sheath through an irregular opening. All cells divide obligatory only once into nanocytes, which grow into the +/- original size and shape before the next division.
