=L. delicio´sus= Fr.—delicious. (Plate XLI, fig. 3, p. 160.) =Pileus= 2–6 in. broad, _orange-brick-color, yellowish or grayish-orange_, becoming pale, fleshy, when quite young _depressed in the center_, margin naked, involute, then plano-depressed or broadly funnel-shaped with the margin unfolded, smooth, slightly viscid, _zoned_ (zones sometimes obsolete). =Flesh= soft, not compact, pallid, colored at the circumference only by the juice. =Stem= 1–2 in. and more long, 1 in. thick, stuffed then hollow, at length fragile, equal or attenuated at the base, spotted in a pitted manner, of the same color as the pileus or paler. =Gills= somewhat decurrent, crowded, narrow, arcuate, often branched, typically _saffron-yellow_, but _becoming pale and always becoming green when wounded_. =Milk= _aromatic, from the first red-brick-saffron_. _Fries._ =Spores= white, spheroid, echinulate 7–8µ _K._; 6µ _W.G.S._; echinulate, 9–10×7–8µ _Massee_; subglobose, 7.6–10µ _Peck_. In woods, under firs, etc. =Pileus= dingy orange-red becoming pale, often greenish. Every part turns to a homely green when bruised. It is from 3 to 5 in. across, thick, convex, then depressed in center, margin at first curved in. =Gills= decurrent, narrow, saffron-color. =Milk= saffron-red or orange changing to green; sweet scented but slightly acrid. I have never seen but one specimen with milk distinctly orange, and changing to green. The milk in this species varies in color, much depending upon moisture. It grows in patches, sometimes in clusters. Edible. _Curtis._ There is no question of its edibility. Old and modern writers applaud it. Each cooks to his liking and thinks his own way best. It requires forty minutes' stewing or baking; less time if roasted or fried. It can be cooked in any way, but, like all Lactarii, it must be well cooked. =L. in´digo= Schw.—(Plate XLI, fig. 2, p. 160.) =Pileus= 2–5 in. broad, at first umbilicate with the margin involute, then depressed or infundibuliform, _indigo-blue with a silvery-gray luster_, zonate, especially on the margin, sometimes spotted, becoming paler and less distinctly zonate with age or in drying. =Gills= close, _indigo-blue_, becoming yellowish and sometimes greenish with age. =Stem= 1–2 in. long, 6–10 lines thick, short nearly equal, hollow, often spotted with blue, colored like the pileus. =Milk= _dark-blue_. =Dry= places, especially under or near pine trees. Not rare but seldom abundant. July to September. _Peck_, 38th Rep. N.Y. State Bot. =Spores= subglobose, 7.6–9µ long _Peck_. West Virginia, North Carolina, New Jersey, Pennsylvania. Solitary and in groups, in pine and mixed woods. July to September. _McIlvaine._
