Lichens Project Area
Lichens are composite organisms comprising, in most cases, an Ascomycete fungus and a unicellular green alga. More than 3200 species are known to occur in Australia and its territories, representing about 400 genera in about 100 families. Lichens are especially diverse in tropical and temperate regions, that is, near the east coast from north Queensland to Tasmania. While species numbers are far smaller in semi-arid and arid parts of the country, their biomass in those regions is considerable and their biological significance profound. ABRS has published the first four lichen volumes of the Flora of Australia and maintains a comprehensive online checklist of Australian species.
