Abstract

Non-geniculate coralline red algae are very common along the Brazilian coast occurring in a wide variety of ecosystems. Ecological surveys of Ilha Grande Bay have shown the importance of these algae in structuring benthic rocky reef environments and in their structural processes. The aim of this research was to identify the species of non-geniculate coralline red algae commonly present in the shallow rocky areas of Ilha Grande Bay, Brazil. Based on morphological and anatomical observations, three species of non-geniculate coralline algae are commonly present in the area: Lithophyllum corallinae, L. stictaeforme and Hydrolithon reinboldii. Here we provide descriptions of these species and provide a key to their identification. This study represents the first record of H. reinboldii from Brazil.
