Geitleribactron Komárek, 1975

Holotype species: Geitleribactron periphyticum Komárek

Original publication and holotype designation: Komárek, J. (1975). Geitleribactron eine neue, Chamaesiphon-ähnliche Blaualgengattung. Plant Systematics and Evolution 123(4): 263-281.

Description: Solitary cells or groups of cells, joined by one end to the substrate. Cell polarized, differentiated in the rounded and sometimes narrowed basal end, attached by the help of a small mucilaginous pad to the substrate (staining !), and in the apical rounded end; they are cylindrical, straight or slightly curved, slightly club-shaped or oval when young, without any sheath. Cell content greyish or pale blue-green, more or less homogeneous or slightly granular. Thylakoids situated peripherally along the cell walls as a visible chromatoplasm. Filamentous involution cells. Cell division perpendicularly to the longer axis of cells, usually asymmetrically in their upper part, rarely in the middle. The upper daughter cells (exocytes) liberate from the sessile part and attach by one end again to the substrate; very rarely separate two exocytes almost simultaneously. Both species grow attached to aquatic plants, filamentous algae, detritus particles and solid substrates in the littoral of clear or slightly eutrophic lakes, ponds and similar aquatic bodies. Known from the temperate zone of Europe (Austria, Czechoslovakia, Finland, Germany).

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
