Gloeocapsopsis Geitler ex Komárek, 1993

Classification:
Empire Prokaryota
Kingdom Eubacteria
Subkingdom Negibacteria
Phylum Cyanobacteria
Class Cyanophyceae
Subclass Oscillatoriophycidae

Holotype species: Gloeocapsopsis crepidinum (Thuret) Geitler ex Komárek

Original publication and holotype designation: Komárek, J. (1993). Validation of the genera Gloeocapsopsis and Asterocapsa (Cyanoprokaryota) with regard to species from Japan, Mexico and Himalayas. Bulletin of the National Science Museum, Tokyo, Series B (Botany) 19(1): 19-37.

Taxonomic status: currently recognized as a distinct genus.

Most recent taxonomic treatment adopted: Komárek, J., Kastovsky, J., Mares, J. & Johansen, J.R. (2014). Taxonomic classification of cyanoprokaryotes (cyanobacterial genera) 2014, using a polyphasic approach. Preslia 86: 295-335.

Description: Unicellular - colonial; colonies microscopic, later agglomerated into macroscopic, disintegrating granular, irregular strata, subaerophytic or submersed, mainly on stony substrates. Cells more or less spherical, later irregular, rounded polyhedral, agglomerated into irregular packets, differently large, with own mucilaginous, limited, firm, lamellated or not lamellated and colored, 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 colored, yellow-brown or orange-reddish to violet. Cell division in different directions in succeeding generations, the cells do not grow into the original form before the next fission. Occasionally division into spherical nanocytes ("Aphanocapsa" or ""). Reproduction by the dissociation of colonies. The type species is marine (stony littoral in the surf zone), and probably with worldwide 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.

Comments: Komárek & Anagnostidis (1999: 274) record a homonym of this genus as Gloeocapsopsis Geitler sine diagn.

Numbers of names and species: There are 9 species names in the database at present, of which 9 have been flagged as accepted taxonomically on the basis of the listed literature under the species name. In some instances, opinions on taxonomic validity differ from author to author and users are encouraged to form their own opinion. AlgaeBase is a work in progress and should not be regarded as a definitive source only as a guide to the literature..

Names: ('C' indicates a name that is accepted taxonomically; 'S' a homotypic or heterotypic synonym; 'U' indicates a name of uncertain taxonomic status, but which has been subjected to some verification nomenclaturally; 'P' indicates a preliminary AlgaeBase entry that has not been subjected to any kind of verification.

Contributors
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in CD format. These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above. The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.

Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
