Amanita jacksonii   (Jackson's slender amanita)
North America
Cap 8–12 cm wide, stem 9-14 cm tall * 0.9-1.6 cm diameter

Amanita jacksonii, also known as Jackson's slender amanita is a medium to large mushroom with a brilliant red or orange cap. It grows solitary or in small clumps on soil in hardwood forests.

Cap conical to convex at first but becoming flat and lighter in colour as it matures. The surface is sticky, lacking scales, smooth with long streaks extending inward from the lighter coloured margin. Gills moderately crowded to crowded, orange-yellow to yellow-orange to yellow. They are free from the stem or slightly attached to it; yellow to orange-yellow. Stem typically slender, slightly tapering upward. The interior is hollow and has a yellow membranous ring near the apex.

Similar species include other Amanita species such as the poisonous Amanita muscaria. The white spots on Amanita muscaria sometimes wash away during heavy rain and the mushroom then may appear to be this species.

Warning Despite the mushroom is considered edible, it should like the other species in the Amanita genus, not be consumed because of the danger of being confused with poisonous species. Only very experienced fungi foragers should consider gathering this species.
