Field Notes
We analyzed sample 7a for the dasysiphonia monitoring project on November 2, 2015, and it was collected on 10/19/15. It's location was N 43.0873 W -70.6560, at a depth of 16 feet.
Supporting Evidence
This species is not Dasysiphonia because this sample has thousands of circular cells along its branches and thallus, whereas Dasysiphonia species branches are one-cell thick and in neat rectangular rows.
This sample is not Dasysiphonia because thallus of my species is much bigger than the invasive species. There is also no destinctive break between the main branch and the side branches like there is in Dasysiphonia.

Beautiful photos too! This is
Beautiful photos too! This is why I love microscopy.... :)
Did this one have a almost spongy texture to it? I think this is the same stuff that I've found in the past and it is quite lovely to look at, even without a microscope. I wonder if we'll figure out what it is some day.
Happy observing,

Felt like rubber
No, it actually felt more like rubber and it was thin :)
Oh, neat! I'll keep an eye

No Invasive?
Lovely, possibly native seaweed? I noticed that all of the other RedRiots samples contained Dasysiphonia japonica. Were you surprised NOT to find this species? Any ideas why your area might not have Dj?
We were surprised
When we were looking through our sample we pulled it apart looking for DJ because everyone else in our class found it in there sample. We were positive we did not find it which I guess is a good thing, but was surprising.
Wow, yes, this does look
Wow, yes, this does look completely different from Dasysiphonia japonica. Nice photos RedRiots5!
Thank you :)
We were absolutely positive this wasn't DJ, all of the reds we found in are sample had millions of cells thoughout the branches and body. Glad you like the photos :)
