| Species | |
Kirchneriella is a genus of green algae in the family Selenastraceae.[2] It is found in freshwater habitats, as phytoplankton or metaphyton.[3]
The genus name of Kirchneriella is in honour of Emil Otto Oskar von Kirchner (1851–1925), who was a German botanist and agronomist.[4]
The genus was circumscribed by Wilhelm Schmidle in Ber. Naturf. Ges. Freiburg vol.7 on page 82 in 189.
Description
[edit]Kirchneriella usually consists of colonies of cells within a thin layer of mucilage. Usually four to 16 are present within a colony, but sometimes they are solitary. Cells are crescent-shaped, containing a single chloroplast with one pyrenoid. They are irregularly distributed within the mucilage.[3]
Species are distinguished from each other based on cell size and shape.[5] The similar genus Pseudokirchneriella was split off from Kirchneriella; it differs from this genus in that its cells lack a pyrenoid.[3] Some authors do not recognize the two genera as being distinct.[6]
Reproduction
[edit]Kirchneriella reproduces by autospores, which are arranged serially within the mother cell. They are released by rupture of the mother cell wall.[6]
