Lactarius rubrilacteus is a species of fungus of the genus Lactarius. It is also known as the bleeding milkcap. The mushroom is typically orangish-brown but bruises green. The cap is 6–14 centimetres (2+1⁄4–5+1⁄2 in) wide and the stem up to 6 cm long. The flesh often exudes a latex when cut and the spore print is beige.

Growing in western North America under conifers from summer to fall, the mushroom is edible but of low interest due to its grainy texture.
