Field Notes
It was a little hard to find the algae because it was so small and growing on other algae. It didn’t float because it was so small it was held down be the other, bigger algae. I moved all the algae around in the container and shook the bigger algae so the smaller stuff fell off. I saw a piece of brown algae with a little piece of red algae hanging off. I broke off the little piece of the algae and made a slide to find out that the red algae was in fact Dasysiphonia. If my hypothesis is correct then this is the farthest down east we have found Dasysiphonia.
Supporting Evidence
Photo of my evidence.
I think I found Dasysiphonia because the main branch is multi celled and branches off into single cell. The algae also has a shepherds hook. This algae shows all the characteristics of Dasysiphonia.

As you can see, the algae in the photo at 100x magnification is double cell at the main branch and branches off into single cell much like Dasysiphonia. This algae also has shepherds hooks at the tips of some of the branches. All of these qualities are qualities of Dasysiphonia which leads me to believe that that the algae in this photo is Dasysiphonia.

I also think this algae is Dasysiphonia because in this photo it also has a multi celled branch and branches off into single celled branches. It also has shepherds hooks at the tips of the branches. All this information leads me to believe that the algae in this photo is Dasysiphonia.

Thanks for all of the sorting you did to find this sample. How abundant is this seaweed in the area?

Best,
