Description

Lactarius deliciosus has a carrot orange cap which is convex to vase shaped, inrolled when young, 4 to 14 cm (1.5–7 in) across, often with darker orange lines in the form of concentric circles. The cap is sticky and viscid when wet, but is often dry. It has crowded decurrent gills and a squat orange stipe which is often hollow, 3 to 8 cm (1–3 in) long and 1 to 2 cm (0.4–0.8 in) thick. This mushroom stains a deep green color when handled. When fresh, the mushroom exudes an orange-red latex or "milk" that does not change color.

In North America, this mushroom is often confused with Lactarius rubrilacteus
