It is a reddish-orange colored mushroom species which can be identified by its yellow gills, large, white, sacklike volva.[5] The cap of the mushroom is 8–12 centimetres (3–4+1⁄2 inches) wide; oval at first, becoming convex, typically with a central bump; sticky; brilliant red or orange, fading to yellow on the margin; typically without warts or patches; the margin lined for about 40–50% of the cap's radius.Its stipe measures 90–140 by 9–16 millimetres (3+1⁄2 in–5+1⁄2 in × 1⁄4 in–3⁄4 in), is yellow and decorated with orange fibrils and patches that are the remnants of a felted extension of the limbus internus of the otherwise white volva.A. jacksonii looks similar to A. caesarea (Caesar's mushroom), which is found in Europe and North Africa, as well as poisonous species of Amanita.The mushroom is considered a choice edible, although it can be misidentified with toxic species such as A. muscaria and A.
