Lactarius scrobiculatus (Fr.) Fr. Cap 7-20cm across, broadly convex with a depressed disc and long inrolled, hairy margin, becoming flatter and broadly funnel-shaped with a smooth margin; pale ochre-yellow to yellow-orange, darker in the center with faint concentric bands of color, bruising dingy brown; very sticky, slimy when dry, scaly, often in rings. Gills adnate to decurrent, quite crowded, broad; whitish with a faint yellow or pink tint, bruising pale pinky-brown. Stem 30-60 x 15-35mm, sometimes tapering to a root-like base; tawny with glazed, yellow-brown spots and some white mycelium on the base; finely downy and pitted. Flesh rigid; white. Latex white, plentiful, quickly changing to sulphur yellow. Odor fruity. Taste burningly acrid. Spores broadly ellipsoid, amyloid, 7.1-8.6 x 5.9-6.8µ; ornamented with warts, some paired, and fine lines making a sparse reticulum, prominences 0.5-lµ high. Deposit bright ochre-yellow with a slight flesh tint. Habitat scattered to gregarious under conifers, particularly in mountain areas. Rare. Found in Oregon. Season September-October. Not edible. Comment My collection had burningly acrid milk, and I feel it should probably be recognized as Lactarius scrobiculatus var. scrobiculatus (Fr.) Fr., but the presence of this variety is not confirmed in North America.
