Extract from Wikipedia article: Amanita roseotincta is a species of agaric fungus in the family Amanitaceae found in North America. It was first described by American mycologist William Alphonso Murrill in 1914 as a species of Venenarius before being transferred to Amanita the same year.
Amanita roseotincta is a species of mushroom that belongs to the genus Amanita. It has a cap that ranges from pinkish-buff to pale orange-brown, often with a darker umbo, and can reach up to 6 cm in diameter. The gills are free, crowded, and white. The stem is typically 4-8 cm long and 0.5-1.5 cm thick, with a bulbous base. In East and Central Texas, Amanita roseotincta has been found growing in association with oak trees, particularly in the fall season, from September to November. It tends to prefer well-drained soils and shaded areas, often fruiting singly or in small groups.
