Diatoms are mostly unicellular, golden brown, green or dark brown algae 2 to 200 microns in size (occasionally several millimetres long), their cell walls composed of silica with an organic coating. Found in all aquatic environments, they can be planktonic, or they can attach to substrata such as rock, sand, mud, plants and animals. At sea, diatoms contribute enormously to the microbial component of a food web that supports most other marine organisms. They also play a role in influencing climate through the exchange of carbon dioxide with the atmosphere (Scott & Marchant, 2005).

An inventory of Australian non-marine diatoms has been provided by Day et al. (1995). The current list includes 938 species and infraspecific taxa known from inshore and offshore waters around Australia and/or from estuarine and other brackish-water habitats.

Click on the links (below) to view species fact-sheets. These contain original publication details, basionyms, other synonyms relevant to Australia, broad type localities, Australian and global distributions, and literature references for Australian records. The fact-sheets have been compiled mainly from comparatively recent sources, including overviews of the diatoms of temperate Australian waters (Jameson & Hallegraeff, 2010; Saunders et al., 2010), eastern Australia (Foged, 1978), the Swan River estuary in Western Australia (John, 1983), a series of substantial papers by E.J.F. Wood and L.H. Crosby (1958–61), and the results of other taxonomic and floristic research.

For publication details, typification and extra-Australian distribution, I have relied heavily on three monumental resources, Catalogue of Diatom Names  , Index Nominum Algarum   and AlgaeBase  , as well as numerous papers, reports and abstracts.

While this aims to be a reasonably comprehensive preliminary list, accepted names, their systematic placement and synonymy and the geographical distribution of taxa are based solely on the literature and the taxonomic judgements therein.

Notification of errors, omissions and updates will be gratefully received and acknowledged.
