Field Notes
When doing Shabbit I only had one class to make slides and get pictures so the challenges was getting pictures and making the slides. When I made the slides I got excited about the first one because I thought it was Dasysiphonia but it wasn´t. Why I studied this site was because it is near Canada.
Supporting Evidence
Photo of my evidence.
When examining this algae I noticed that it looked like Dasysiphonia until I saw the main branch and that's when I knew it wasn't Dasysiphonia. 400x magnification

Its definitely not Dasysiphonia because it doesn´t have single celled areas and it does not branch off like Dasysiphonia. 400x magnification

The first image is lovely, but it doesn't show the correct pattern of cellular construction. The last image is probably a hydroid (animal).

Thanks for your work on this!
