The calcareous brown alga Newhousia imbricata (Dictyotales, Phaeophyceae) was found from postglacial reef deposits collected during Integrated Ocean Drilling Program Expedition 310 from Tahiti. The alga is composed of successive tiers of bilayered laminae, each consisting of a basal cuboid hypodermal cell bearing smaller epidermal cells (one or two in cross-sectional profiles and three or four in long-sectional profiles). The laminae are separated by extracellular cement. Modern N. imbricata is known only from the Hawaiian Islands; this is the first reported occurrence of fossil N. imbricata.
