Non-Geniculate Coralline Algae (Corallinales, Rhodophyta) on Heron Reef, Great Barrier Reef (Australia)

From the journal


This is the first modern, comprehensive account of non-geniculate coralline algae (Corallinales, Rhodophyta) occurring on the Great Barrier Reef (Heron Reef). Species were identified in a modern context, using reproductive and vegetative anatomy as diagnostic features. In a collection of 300 specimens, 11 different species were identified. Eight of the species were found exclusively on calcareous substrata, one was exclusively epiphytic, while the remaining two were both epiphytic and found growing on calcareous substrata. Although none of the species are new to science, one is newly recorded for Australia (Hydrolithon reinboldii) and 5 are newly recorded for the Great Barrier Reef region (Spongites fruticulosus, Lithophyllum frondosum, L. pustulatum, Mastophora pacifica and Mesophyllum erubescens). Collections made by A. B. Cribb in the 1960s on Heron Reef were also studied, once again using reproductive and vegetative anatomy as diagnostic features. Illustrations of each species and a tabular key are provided to facilitate non-geniculate coralline algal identification on Heron Reef. Information on their distribution and growth-forms are provided along with references to more detailed morphological accounts and published illustrations. The reported species are compared to findings from other tropical reef systems.
