Field Notes
During this study we were looking for Dasysiphonia in the samples that our seventh grade class received from Little Bay. We were interested in finding where Dasysiphonia is, and how far east it goes and if it's up by Canada. We took great care of the samples to make sure there was no cross contamination.
Supporting Evidence
Photo of my evidence.
There are two types of algae in this picture. In the corner you can see a multi cell algae. In the middle there is single celled algae. Both of these algae's are not Dasysiphonia because they do not have axial growth. Also the algae that is single cell doesn't have three cells at the base of the branches.
Photo of my evidence.
This photo is not Dasysiphonia because it doesn't have the three cells at the main branch. It mainly doesn't have axial growth. You could tell that there was also no shepherds hook, supporting the evidence for this not being Dasysiphonia.
Photo of my evidence.
This photo is not Dasysiphonia because it is multi-celled. Although the algae does have axial growth it is still not Dasysiphonia.

You are correct, none of these has the right morphology to be Dasysiphonia.

Keep up the great work!
