Staurodesmus Teiling
The species are unicellular, the sides of the semicell are extended
laterally into angles which end in a spine, mucron, wart or papilla.
The cell wall is smooth or punctate but never granular or aculeate.
Many species are planktic. (Croasdale, H., Flint, E. & Racine,

Staurodesmus indentatus (West) Teiling
Dimensions: L. 2044 µm, B. 1828 µm. Processes 1335 µm. Teiling
1967. |

Staurodesmus mamillatus var. maximus (Nordst.) Teiling
Dimensions: L. 1840 µm, B. 1528 µm. Processes 1532 µm. Teiling
1967. Coesel 1994 and Lenzenweger 1997 include Std. mamillatus
in the Std. cuspidatus complex because of unclear separation of
characters. |
