Is there anyone that can tell me the genera and/or species of of this algae?
They are from mid-Permian of South China, which was located around the equator.
It looks like Dasycladus.
Yes, it is. Could you identify them on genus level? For example, Eogoniolina or Mizzia.
Do you record their color and whether its branched or not. also, it might be useful to classified their cross section. then you can decide if it's Dasycladus or not.
Perhaps Salpingoporella
May the attached file help you.
