Also known as Barigoule, bricked, Catalan, Red cow, Polish, Roussillon, sanguine, or pine mushroom orange.
Cap: 5 to 15 cm, fleshy, initially convex with rolled edges, then flattening into a cup or funnel shape; smooth and slimy, orange-red with darker concentric zones, spotting greenish.
Gills: Fairly close, fragile, orange and decurrent, staining green when handled.
Stem: 3.5 to 7 x 1 to 2 cm, firm then hollow, brittle; cylindrical matching the cap color, often with small surface dimples.
Flesh: Firm and brittle, white turning orange on exposure, greening with age; exudes orange milk that stains urine; pleasant aroma with a mildly acrid taste.
Habitat: Common from August to late October under pines and spruces in mixed forests, especially grassy areas.
Milk caps with red or orange milk and greening flesh are edible; 'The Sanguine' rivals the Delicious in flavor.
