At home, I moistened the coating and carefully scraped some off to mount on a microscope slide. Even under low power, I could see what looked like dark awl shaped hairs sticking up from the surface of mass of algal cells. At first I wondered whether the hairs could have come from the leaf itself, even though I wasn't aware that Cherry Laurel leaves had any. A quick check of a portion of the leaf without the alga revealed absolutely no hairs, so I am left with the conclusion that the apparent hairs are in some way connected with the alga.
I doubt whether I will ever find out what the alga is, assuming it is and alga, and I am not fishing for an identification, but does anyone know what the 'hairs' are and what is their function?
