Roridomyces austrororidus, commonly known as the austro dripping bonnet, is a species of agaric fungus in the family Mycenaceae. Described as new to science in 1962 by American mycologist Rolf Singer, it is found in South America, New Zealand, and Australia, where it grows on rotting wood.
The fruit bodies (mushrooms) have several distinguishing characteristics that facilitate identification, including thick, white, mucilaginous stipes, and white to pale cream, convex caps that measure 1–2 cm (0.4–0.8 in). The gills are white, widely spaced, and have a fused or decurrent attachment to the stipe. Spores are smooth, ellipsoid, and measure about 9–15 by 6–9 micrometres. The smooth and white stipes are 4–6 cm (1.6–2.4 in) long and 0.1–0.2 cm (0.04–0.08 in) thick, and covered with a thick coating of gluten.
The species was first described as Mycena austrororida by mycologist Rolf Singer in 1962, based on specimens he collected from Masatierra, in the Juan Fernandez Islands, Chile. Karl-Heinz Rexer transferred it to the newly circumscribed genus Roridomyces in his 1994 doctoral thesis. The name Mycena veronicae, published by New Zealand mycologist Greta Stevenson in 1964, is a synonym of M. austrororida.
