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.
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]
Kirchneriella reproduces by autospores, which are arranged serially within the mother cell. They are released by rupture of the mother cell wall. [6]
