Supporting Evidence
Photo of my evidence.
It is known that Dasysiphonia Japonica has a multicellular main branch, with single-celled branches coming off of it, which can be seen in this picture. Also seen is green growth on the branches of the Dasysiphonia.

In this picture, the growth earlier mentioned can be seen in larger numbers on these branches. Additionally, the branches exhibit axial growth which is another indicator that the sample could be Dasysiphonia Japonica.

This is another image we took in order to see the structure of the branches as well as the growth coming off of them.

We did not take a very good picture of the observation site but found one online for the area. (

Hi cgiorda2018,

Another stellar observation! Your sketches are always wonderful - thanks for sharing! While that's a good site photo, we're going to put the special data set image in, just like your other observation.

Thanks for posting your data and helping us monitor Dasysiphonia!
