Diagnosis:
Type species: Gloeocapsopsis crepidinum (Thuret) Geitler 1925. - Seven species.
Descriptions:
Komárek & Anagnostidis (1998): Rarely solitary cells, mostly micro- or macroscopic, irregular, formless or granular colonies, composed of densely, irregularly aggregated cells or their small goups, surrounded by mucilaginous envelopes. Cells subspherical, more or less irregular-rounded in outline, sometimes slightly elongate (never spherical), enveloped by thin, narrow, clearly delimited, rarely slightly diffluent, sometimes feebly lamellate, often coloured sheaths (yellow, red, rusty red, etc.), usually following the cell outline.
Komárek (1992): Unicellular- colonial; colonies microscopic, later agglomerated into macroscopic, disintegrating granular, irregular strata, subaerophytic or submerse, mainly on stony substrates. Cells more or less spherical, later irregular, rounded polyedrical, agglomerated into irregular packets, differently large, with own mucilaginous, limited, firm, lamellated or not lamellated and colou- red, usually not very wide envelopes which sometimes more or less copy the cell shape; groups of cells unified together by the common mucilaginous sheath. Cells with blue-green, usually homogeneous content. Sheaths coloured, yellow- brown or orange-reddish up to violet.
Genotype differences, molecular data:
Reproduction strategies, life cycles, cell division:
Komárek & Anagnostidis (1998): Cell division irregularly in various planes in successive generations. Reproduction by liberation of divided and ensheathed cells from ruptured mother sheaths. Nanocyte production rarely observed in several species (?). Occasional presence of enlarged resting cells with thick, firm and usually intensely coloured envelopes.
Komárek (1992): Cell division in different directions in succeeding generations, the cells do not grow into the oriminal form before the next fission. Occasiollally division into spherical nanocytes ("Aphanocapsa" or "Gloeocapsa" - status). Reproduction by the disintegration of colonies.

Ecology, ecophysiology, ecological significance:
Komárek (1992): The type species is marine (stony littoral in the surf zone), and-probab1y with world-wide distribution, other species grow subaerophytically on wet or periodically moistened rocks, walls and wooden substrates (known mostly from the temperate zone and high mountains of Eurasia), but probably more distributed. The subaerophytic mode of life causes the formation of different, morphologically variable modifications. Probably more species exist.
