which sigmoid diatom is this?

#1 Post by Free2Fish » Wed Mar 06, 2024 11:01 pm

I've spent quite a bit of time searching the various diatom keys on the internet but haven't been able to come up with an ID for this sigmoid diatom. Any ideas out there?
Thanks, Harry

Hi,

Maybe lookup Nitzschia sigmoidea ?
