Lemmermanniella L.Geitler, 1942

Holotype species: Lemmermanniella pallida (Lemmermann) Geitler

Original publication and holotype designation: Geitler, L. (1942). Schizophyta: Klasse Schizophyceae. In: Die natürlichen Pflanzenfamilien, Sweite Auflage. (Engler, A. & Prantl, K. Eds) Vol.1b, pp. 1-232. Leipzig: Wilhelm Engelmann.

Description: Unicellular-colonial; colonies microscopic, spherical, irregularly spherical to irregular, mucilaginous, free-living (mainly floating) in freshwater reservoirs, with cells situated more or less in the peripheral layer, without any mucilaginous stalks. Cells are oval to rod-like, without aerotopes, placed in the surface layer tangentially and irregularly or in small groups, sometimes more or less parallel. Mucilage is colorless, fine, limited or diffluent, sometimes slightly concentrically lamellated. Cell division always perpendicular to the lengthwise axis of elongated cells, in one and the same plane in successive generations; however, the daughter cells soon shift from the original direction and form groups with parallel situated cells. Colonies reproduce by the "budding" of small daughter colonies, or by dissociation of colonies into small groups of cells or to solitary cells enveloped by slime, up into solitary cells. The type species occurs rarely planktonic in slightly eutrophic lakes in western Baltic region (southern Norway and Sweden, Denmark, northern Germany); two other species were described from small reservoirs with water plants in eastern Slovakia (Czechoslovakia), however, their generic position remains questionable.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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