Schottera nicaeensis (Phyllophoraceae, Gigartinales), presently known only from the western Mediterranean Sea and the northeastern Atlantic coasts of Europe, is reported for the first time from the Melbourne region of Port Phillip Bay in southeastern Australia. The species is perennial in the Bay, although tetrasporophytes and cystocarpic plants are commonest in late spring and early summer. This seasonal pattern, and the vegetative habits of plants during the whole of the year, show similarities to populations described by other workers for Northern Hemisphere localities where comparable water temperature and daylength regimes obtain. The small Australian S. nicaeensis community is found at 5–9 m depths and is concentrated on lighthouse foundations adjacent to the main Port of Melbourne shipping channel. It is hypothesized that the species has recently been introduced into Port Phillip Bay, and a scenario for its possible means of import on ships is suggested.
