Amanita australis is a species of fungus in the family Amanitaceae. It produces small- to medium-sized fruit bodies, with brown caps up to 9 centimetres (3+1⁄2 inches) in diameter covered with pyramidal warts. The gills on the underside of the cap are white, closely crowded together, and free from attachment to the stem. The stem, up to 9 cm (3+1⁄2 in) long, has a ring and a bulbous base. The mushroom may be confused with another endemic New Zealand species, A. nothofagi, but can be distinguished by differences in microscopic characteristics.
The species was first described by New Zealand mycologist Greta Stevenson in 1962, along with a purported unique species which 30 years later was reduced to synonymy with A. australis. The species is found only in New Zealand, where it occurs in Leptospermum and Nothofagus forests.
