Description
The yellowish cap is up to 12 cm (4.7 in) in diameter and marked with orange spots. Hemispherical when young, it extends and flattens into a convex shape. The surface texture starts slightly velvety, becoming smoother with age. The pores on the cap underside are red, while the bulbous stipe yellow overlain with a prominent red net-like pattern, and measures up to 9 cm (3.5 in) high by 5 cm (2.0 in) thick. The flesh is thick and hard. It is yellow, except for the stipe base where it is deep red. It has an acidic taste. The smell is indistinct. All parts of the mushroom stain a deep blue when cut or bruised.
Similar species. It resembles Imperator torosus but can be distinguished by its red (rather than yellow) pores.
