Field Notes
I felt very excited every time I made a new wet mount, because everytime I didn't know if it was or wasn’t Dasysiphonia, which I don’t believe I actually did find any but it was still fun. We used compound microscopes to try to find the Dasysiphonia and we used IPads to take the photos.
Supporting Evidence
Photo of my evidence.
This is a 40x photo and as you can see the tips have multi cells so it isn't Dasysiphonia.

This is a 100x photo that also leads me to believe that I didn't find Dasysiphonia because it’s multi celled.
Photo of my evidence.
This photo is 400x and you can't really tell but it’s the same plant just zoomed in so I wanted to show a closer image to it and it looks nothing like Dasysiphonia because there is multi cells so I know now I didn’t find Dasysiphonia.

I put in the wrong coordanites they are actually lattitude 43.0389 longitude 68.8959

We've put in the updated coordinates, but they still look off. Can you please double check and let us know. Thank you!
