Gerd says:
‘This is a Micrasterias radiosa, a microalga belonging to the huge group of desmids.

These microalgae are also called ornamental algae, because all forms have at least one axis of symmetry. These algae are much sought after by microscopists because of their outstanding beauty.

The Desmids prefer boggy biotopes with low pH values and are sometimes very rare. The form shown here comes from the algae collection of the University of Cologne, with which I have been working with for many years.’
