Field Notes
It was hard finding Dasysiphonia in are Ragged island sample site because I just kept finding the same algae and other stuff that I didn't know what was. We used microscopes to find our samples and made our own wet mounts. We only got to work from a little sample cup.
Supporting Evidence

Not found. I didn't find Dasysiphonia because there's way too many cells, does not have axial growth, and doesn't have a shepards hook. 400x

The top image is probably Polysiphonia. The middle image is probably a hydroid such as Dynamena. I'm not sure about the bottom ID, but it is definitely not Dasysiphonia.

Thanks for your work on this project!
