S. chordalis and G. gracilis seem macroscopically very similar. Does somebody know how to differentiate these two species? What are the main differences for a rapid identification?
(excluding the identification based on agar or carrageenan in the cell wall)
Daniel,
thank you very much for the information that, I think, will be very helpful.
We will check it soon. Hoping that what we'll observe, will confirm our identification of the seaweed species. Could I send you a photography of the cross section if I'm not sure and need a confirmation? Thank you again for your help.
Regards,
Kevin
I observed a few sections of our seaweed. With the information you have provided, I think it is indeed Solieria chordalis. Please see the picture below.
We could eventually be interested in molecular analyses. I'll let my supervisors (N. Bourgougnon and G. Bedoux, I think you met them at XXIst ISS and ISAP) contacting you.
Thank you again for your help.
Regards,
Kevin
