I know, it was annoying that none of the web pictures matched rynon's pics or the one in my South Pacific algae book by Littler & Littler. However, the Nitophyllum in their book is a much closer match than Fauchea or anything else I could find, even the reproductive structures matched. It was listed as Nitophyllum sp. which means that it's an undescribed species (or that they couldn't identify it) and therefore not likely to be on any website.
