Field Notes
When doing this cell project I had some troubling encounters like taking pictures and getting it focused. Some of the exciting things that I found was this algae that looked really cool and it had many spikes. Also there was no big cell walls it was just has mini cells all clumped up in a bunch. The reason why we did this research is to see if we could find Daisysiphonia in areas up north near Canada. Also we did it because Daisysiphonia is a bad thing in environments and we wanted to know where it is.
Supporting Evidence

When examining this piece of algae I noticed that it has multiple cells and clumps up. Also the algae does not have axial growth. 400x magnification

When studying this piece of algae I noticed it doesn't have a cell wall or cell membrane it just has tons of tiny cells. Also it only splits off of the main branch of the algae. 400x magnification

When studying this piece of algae I was surprised how it had many spikes that split off of the main branch. I also noticed that you could barely see the cells when it was fully zoomed in. 400x magnification

The closest possibility is the top image, but it shows multiaxial cell arrangements to the branch tips, so is probably Polysiphonia. See this site for good images of Dasysiphonia:
