Field Notes
Having trouble making the slides so that they didn’t have air bubbles and so they didn’t have any space in between the slide and the slide cover slip, that was probably the most hardest challenge I encountered.
Supporting Evidence
Photo of my evidence.
I don’t think I found Dasysiphonia because Dasysaphonia has shepherds hooks and this one doesn’t have any shepherds hooks and it seems more blackish than a red and dasysiphonia is red.

I think that I might have found Dasysiphonia because it has the shepherds hooks and because it has the reddish color and Dasysiphonia is red
Photo of my evidence.
I don’t think that this one is it because you can barely see the cells and you can’t see what the tips look like, the tips are not shepherds hooks and to add this looks more blackish or brownish than red.
