Micrasterias pinnatifida

Post by NikonUser »

EDIT: was "Algae ID request", now identified thanks to Gerd

From a FW lake. Shape is discus-like (biconvex) with surfaces pitted? as in right image.
I've looked through several algae images on the WWW with no success. Scenedesmus seems a possibility
Oly 40x S Plan Apo + 2.5x NFK eyepiece
ZS PMax stacks of 1µ frames.

Hi NikonUser,

a wonderful alga and perfectly presented.
I don't think this is a scenedesmus,
i think it is a Micrasterias, a desmid,
probably Micrasterias pinnatifida.

Thanks for sharing,
Gerd
