Non-marine algae of Australia : 4. Floristic survey of some colonial green macroalgae (Chlorophyta)

Abstract

Four genera in the Tetrasporales (Chlorophyta) are documented from Australia: Tetrasporidium javanicum Möbius is newly recorded, Tetraspora gelatinosa (Vaucher) Desvaux is confirmed for this country, and the distribution of Palmellopsis gelatinosa Korshikov and Parallela novae-zealandiae E.A.Flint are extended. A further gel-forming damp terrestrial taxon, Gloeocystis polydermatica (Kützing) Hindák (Radiococcaceae, Chlorococcales) is newly reported from Australia, and the conspicuous, gel-coated, Coleochaete areolata (Coleochaetaceae, Coleochaetales) is described as new to science. These six taxa are among the most commonly encountered colonial green macroalgae in Australian inland areas.
