Spirogyra

Hi all,

At my garden house there is a ditch that is blooming with algae right now, a green slime is covering the surface. I've taken a sample from it:

A beautyful photo! It's Sprogyra sp., that's right but I can't say more.

Hallo Angie,

Thank you for your compliments! As far as I can see there are 4 or 5 different Spirogyra species visible in the picture. But I'm certainly not sure about that,  I'm not an Algenexpert. Viele Grusse,

Rolf

Good morning Rolf

Spirogyra can only be identified when conjugating, they build characteristic zygotes respectivly. What you see here are various stadiums of decay of the chloroplasts, I'm sorry to say.

Hallo Bernhard,

Thank you for your insight. That's one of the nice things of doing microscopy, that you constantly learn new facts. Fascinating. How about the desintegrating chloroplasts, it seems that the spiral shape is still intact in most filaments. Best regards,

Rolf
