In mixed woods. Common. August to October.
Pronounced one of the best esculent species by all authorities.
R. heterophyl´la Fr. Gr—differing; Gr—a leaf. (Gills differing in length.) Pileus very variable in color, but never becoming reddish or purple, fleshy, firm, convexo-plane then depressed, even, polished, the very thin pellicle disappearing, margin thin, even or densely but slightly striate. Flesh white. Stem solid, firm, somewhat equal, even, shining white. Gills reaching the stem in an attenuated form, very narrow, very crowded, forked and dimidiate, shining white.
Taste always mild, as in R. cyanoxantha, from which it differs in its smaller stature, in the pileus being thinner, even, never reddish or purplish, with a thin closely adnate pellicle, in the stem being firm and solid, and in the gills being thin, very narrow, very crowded, etc. The apex of the stem is occasionally dilated in the form of a cup, so that the gills appear remote. Fries.
Spores echinulate, 5×7µ W.G.S.; 7–8µ diameter Massee.
Common. Woods. July to November.
Edible, of a sweet nutty flavor. Stevenson.
R. heterophylla is very common. Its smooth, even pileus, colored in some dingy shade of green, distinguishes it. It is much infested by grubs. Specimens for the table should be young and fresh. Wilted specimens are unpleasant.
R. fœ´tens Fr.—fœtens, stinking. Pileus 4–5 in. and more broad, dingy yellow, often becoming pale, thinly fleshy, at first bullate, then expanded and depressed, covered with a pellicle which is adnate, not separable, and viscid in wet weather, margin broadly membranaceous, at the first bent inward with ribs which are at length tubercular. Flesh thin, rigid-fragile, pallid. Stem 2 in. and more long, ½-1 in. thick, stout, stuffed then hollow, whitish. Gills adnexed, crowded, connected by veins, with very many dimidiate and forked ones intermixed, whitish, at the first exuding watery drops.
Fetid. Taste acrid. Very rigid, most distinct from all others in its very heavy empyreumatic odor. In very dry weather the odor is often obsolete. The margin is more broadly membranaceous and hence marked with longer furrows than in any other species. It differs from all the preceding ones in the gills at the first exuding watery drops. The gills become obsoletely light yellow, and dingy when bruised. Fries.
