Protist both microbial eukaryotes and macroscopic organisms that do not fit into the other traditional kingdoms. In cladistic systems (classifications based on common ancestry), there are no equivalents to the taxa Protista or Protoctista, both terms referring to a paraphyletic group that spans the entire eukaryotic tree of life. In cladistic classification, the contents of Protista are distributed among various "supergroups" (SAR, such as protozoa and some algae, Archaeplastida, such as land plants and some algae, Excavata, which are a group of unicellular organisms, and Opisthokonta, such as animals and fungi, etc.). "Protista", <nowiki>"Protoctista"</nowiki> and "Protozoa" are considered obsolete. However, the
Fungi of Australia Fungi of Australia The Fungi of Australia form an enormous and phenomenally diverse group, occupying a huge range of freshwater, marine and terrestrial habitats with many ecological roles, for example as saprobes, parasites and mutualistic symbionts of algae, animals and plants, and as agents of biodeterioration. Where plants produce, and animals consume, the fungi recycle, and as such they ensure the sustainability of ecosystems. Knowledge about the fungi of Australia is meagre. Little is known about aboriginal cultural traditions involving fungi, or about aboriginal use of fungi apart from a few species such as Blackfellow's bread ("Laccocephalum mylittae"). Humans who
