=R. ochra´cea= Fr.—_ochra_, a yellow earth. =Mild.= =Pileus= about 3 in. across. =Flesh= rather thick at the center, becoming thin toward the margin, pale ochraceous, soft; convex then expanded and depressed, margin coarsely striate, pellicle thin, viscid, ochraceous with a tinge of yellow, disk usually becoming darker. =Gills= slightly adnexed, broad, scarcely crowded, ochraceous. =Stem= about 1½ in. long, 5–7 lines thick, slightly wrinkled longitudinally, ochraceous, stuffed, soft. =Spores= globose, echinulate, ochraceous, 10–12µ diameter. In pine and mixed woods. The mild taste and ochraceous color of every part, including the flesh, separate the present from every other species. Commonly confounded with Russula fellea, but known at once by its mild taste. Agreeing most nearly with R. lutea in color, but differing in the softer flesh, which becomes ochraceous upward; sulcate margin of the pileus, and broader, less crowded gills. =Pileus= persistently ochraceous, disk usually darker. =Stem= sometimes yellow, sometimes white. _Fries._ North Carolina, borders of woods, _Curtis_; California, _Harkness and Moore_. Fries says that the flavor is mild, but Roze places it in the list of suspected species, although he notes it as not acrid; it may be inferred that he considers the flavor unpleasant. _Macadam._ “Like chicken,” not common. Boston Myc. Club Bull. 1896. =R. lu´tea= (Huds.) Fr.—_luteus_, yellow. =Pileus= 1–2 in. broad, _yellow_, at length becoming pale, and occasionally wholly white, thinly fleshy, soon convexo-plane or plano-depressed, sticky when moist, _even_ or when old obsoletely striate _at the margin_. =Flesh= white. =Stem= ½ in. long, 3–4 lines thick, stuffed then _hollow_, soft, fragile, equal, even, white, never reddish. =Gills= somewhat free, connected by veins, _crowded, narrow_, all equal, ochraceous-egg-yellow. Always small, very regular, taste mild. _When young the pileus is always of a beautiful yellow._ _Fries._ =Spores= yellow, echinulate, 8µ _W.G.S._; globose, rough, 6–7µ _C.B.P._; 8–10×7–8µ _Massee_. Allied to R. vitellina, but differs in having the margin of the cap even, and but little odor. The plant I have so referred has the gills at first white and the stem yellow like the pileus; it may be a new species. In beech woods, _Morgan_; West Virginia, Pennsylvania, New Jersey, in mixed woods, often under beeches, August to November, _McIlvaine_. The plants I have found have white gills when young (few species have not), but rapidly become yellow. The stem is usually white when young, and sometimes remains so, but often becomes more or less yellow. It is a pretty species. The flavor is not as strong as in some species, but is delicate.
