=C. Orcel´la= Bull.—=Pileus= fleshy, _soft_, plane or slightly depressed, often irregular, even when young, _slightly silky, somewhat viscid when moist_, white or yellowish-white. =Flesh= white, taste and odor farinaceous. =Gills= deeply decurrent, _close_, whitish then flesh-colored. =Stem= short, solid, flocculose, often eccentric, thickened above, white. =Spores= elliptical, 9–10×5µ. Generally a little smaller than the preceding species, softer and more irregular, but so closely allied that by some it is considered a mere variety of it. It is said to be edible and of delicate flavor. It occurs in wet weather in pastures and open places. _Peck_, 42d Rep. N.Y. State Bot. Grows in oak woods, Angora, West Philadelphia; Mt. Gretna, Pa. Qualities same as C. prunulus. Delicious. =C. pascuen´sis= Pk.—pasture. =Pileus= fleshy, compact, centrally depressed, _glabrous, reddish or pale yellowish_, the cuticle of the disk cracking into minute areas. =Gills= rather narrow, close, decurrent, whitish, becoming flesh-colored. =Stem= short, equal or tapering downward, solid, glabrous, colored like the pileus. =Spores= subelliptical, pale incarnate, 7.5–10×5–6µ. =Pileus= 2–3 in. broad. =Stem= 8–18 lines long, 4–6 lines thick. Pastures. Saratoga county. The species is related to C. prunulus from which it is distinct by its shorter, paler spores, its glabrous pileus cracked in areas on the disk and tinged with red or yellowish and by its paler gills. From C. pseudo-orcella it differs in its glabrous pileus with no silky luster and in its closer gills. Its odor is obsolete but it has a farinaceous flavor. It is probably esculent, but has not been found in sufficient quantity to afford a test of qualities. _Peck_, 42d Rep. N.Y. State Bot. =C. unitinct´us= Pk.—one-colored. =Pileus= thin, _submembranaceous_, flexible, convex or nearly plane, centrally depressed or umbilicate, glabrous, subshining, often concentrically rivulose, grayish or grayish-brown. =Flesh= whitish or grayish-white, odor obsolete, taste mild. =Gills= narrow, moderately close, _adnate or slightly decurrent_, colored like the pileus. =Stem= slender, straight or flexuous, subtenacious, equal, slightly pruinose, grayish-brown, with a close white myceloid tomentum at the base and white root-like fibers of mycelium permeating the soil. =Spores= elliptical, 7.5×5µ. Var. _al´bidus_. Whitish or grayish-white, not rivulose. Gills broader. Spores brownish flesh-color. =Pileus= 6–16 lines broad. Stem about 1 in. long, 1 line thick. Woods of pine or balsam. Albany and Essex counties. Autumn. The variety is a little paler than the typical form, with gills a little broader, but is probably not specifically distinct. _Peck_, 42d Rep. N.Y. State Bot. I have not seen this species. Edibility not reported. _B._ SPORES ANGULAR OR IRREGULAR. 1. _Pileus not hygrophanous._
