Amanita pseudovolvata is a species of mushroom that belongs to the genus Amanita. It has a cap that ranges from 3-8 cm in diameter, typically reddish-brown to brown in color, and often features a distinctive umbo. The stem is 4-10 cm long and 0.5-1.5 cm thick, with a volva that is often broken up into small, patchy fragments. In East and Central Texas, Amanita pseudovolvata has been found growing in association with oak and pine trees, typically in well-drained soils and under humid conditions. Fruitings often occur from late summer to early fall, particularly after heavy rainfall events.
