Pediastrum - a tiny Alga

Post by NikonUser »

EDIT: title changed from Desmid
Another incredible (Desmid) Alga from a local pond.
I'm fascinated by the diverse shapes of these organisms.

Hello NU,

I like very much your pictures. Congratulations!
(If I remember well Pediastrum is not a Desmid, but an alga from the Clorophyllaceae).

Thanks Franz.
You are correct, from Wikipedia
"Pediastrum is a genus of algae, in the family Hydrodictyaceae. It is a nonmotile coenobial (fixed number of cells) green alga that inhabits freshwater environments."

Nice find. I can't wait to see one of these. Is each one of those X shaped things a single cell?
