Key features

Cap rusty red-brown, with a small umbo (papilla) in the center and a depression around it. Milk white, unchanging, very strongly burning on the tongue after a dozen or so seconds. Stem the color of the cap, slender. Mycorrhizal with pine, abundant in pine forests on moss. Conditionally edible after soaking and parboiling (tradition).
