The caps of the fruit bodies are golden orange, with a yellow pore surface on the underside, and a reticulated (network-like) stem.

The species was first described scientifically by English mycologist Miles Joseph Berkeley in 1872, based on specimens collected in North Carolina and sent to him by Moses Ashley Curtis.

[4] Because the fruit bodies stain the collector's hands yellow, Rolf Singer in 1947 placed the species in Pulveroboletus, despite the lack of a partial veil characteristic of that genus.

The stem surface is usually reticulate at least on the upper portion of mature specimens, although this characteristic is less pronounced or absent in young individuals.

The cheilocystidia (cystidia on the tube edge) are abundant, thin-walled, broadly club-shaped to sphaeropedunculate (rounded and with a short stalk).

The pleurocystidia (cystidia on the tube face) are abundant, think-walled, broadly ventricose (swollen in the middle) or sometimes club-shaped.

The cap cuticle is made of hyphae with bright yellow encrusted crystals in water that dissolve in potassium hydroxide to produce a diffuse lemon-yellow pigment.

[8] The fruit bodies of Aureoboletus auriflammeus grow singly, scattered, or in groups on the ground in woods in a mycorrhizal association with oaks.
