Nicola Cantasano

Dear Vijayan,

the only image that I could identify is the image 81. It could be a Chrysophycea belonging to the order of Silicoflaggelatae. Probably it is the species Dictyocha fibula.

Best regards.

Maria Van Herk

Image 31 could be Eunotia, 25 and 64 look like Desmodesmus and 39 could be a centric diatom.
