The first monographic account of the south-eastern Australian representatives of the Corallinaceae, subfamily Mastophoroideae (Corallinales, Rhodophyta) is presented. The Mastophoroideae contains eight extant genera, four of which [Hydrolithon, Mastophora, Neogoniolithon, Pneophyllum] were confirmed to occur in south-eastern Australia. Hydrolithon is represented by six species (H. farinosum, H. improcerum, H. munitum, H. onkodes, H. rupestre and H. samoënse). Pneophyllum is represented by three species (P. coronatum, P. fragile and P. submersiporum) while Mastophora and Neogoniolithon are represented by a single species each (Mastophora pacifica and Neogoniolithon brassica-florida). Morphological and anatomical accounts are provided, including keys to genera and species, comparisons with related south-eastern Australian mastophoroid species, information on distribution, seasonality, habitat and nomenclature. Brief biogeographical comparisons between south-eastern Australia and other Australasian regions are also made.
Sincere thanks are due Chris O’Brien, David Hardin and Nick Yee who assisted in collecting specimens from NSW; Sascha Brand, Petra Ringeltaube, Robert Harvey and Andrea Schmitt for help in field collecting in Queensland. Trevor Phillips (Department of Botany, La Trobe University) assisted with photographing specimens. Financial support provided by the Australian Research Council to the third author and an Australian Postgraduate Award Scholarship to the first author, are also gratefully acknowledged.

1 Current definitions of the term ‘palisade’ refer to the ratio of cell height to length (height at least 2–4 times cell length) (Woelkerling 1988, fig. 20). (Palisade cells only occur in the basal filaments of certain genera and primary pits are only visible in longitudinal section.)
2 Gametangial conceptacles of Neogoniolithon have not been found in south-eastern Australia but are known from southern Australia. For detailed data and illustrations of gametangial conceptacles in Neogoniolithon brassica-florida see Penrose (1992a, as N. fosliei).
