Supporting Evidence
Photo of my evidence.
Though the stems may not be as clear, this picture shows the axial growth of our sample, which is one of the defining aspects of Dasysiphonia Japonica.
Photo of my evidence.
This photo also shows the axial growth, but more clearly presents the image of the unicellular branches coming off the multicellular main stem, which is another characteristic of the Dasysiphonia that was found in our sample.
Photo of my evidence.
The unicellular stems and the multicellular main branch are shown clearest in this picture. We also did not find any shepherds hooks, which are found on similar looking species.

You have done a great job of capturing good diagnostic features.

Hi cgiorda2018,

I am once again impressed by your scientific sketches! You do a really great job capturing the little details of how D. japonica looks under the microscope.

Thanks for sharing,
-MB

Really nice photos and descriptions here. Sometimes it can be hard to see the multicellular main branch but you captured it well here.
