It is not Trachelophyllum, and, despite its rather hairy appearance, it is not a ciliate. :) It appears to be a rigid alga of some kind. Are there clavate diatoms? Photosynthetic critters are outside my wheelhouse. ;)

Thanks for the ideas. It sure looks hairy. I can't find anything like it in all my books or online references for marine plankton.
