Amanita ochrophylloides is a large mushroom of the genus Amanita native to southeastern Australia. Amanita ochrophylloides was first described by Derek Reid, head mycologist of Kew Gardens, in 1978. He noted that this mushroom differed from the related Amanita ochrophylla in the shape of its spores, as well as the remnants of the membrane across the cap. The initial collection was of mushrooms growing on rocky black soil under peppermint gums and bracken at an altitude of 850 m (2800 ft) southeast of the town of Matlock in Gippsland, Victoria.
