Its spores darken when shed in quantity, have a granulated and light-lilac appearance. It is a solitary grower, sometimes reaching the height of six inches. The upturned, wavy pileus, showing the purple gills in contrast with the pale Naples-yellow of the cap is markedly attractive. The stem is often rough with fibers, hard and tough. The caps are tough. It grows in grassy woods and open places. The novice, even the expert, will be puzzled to place it in its genus. Specimens were sent to me by Miss Lydia M. Patchen, Westfield, N.Y., and E.B. Sterling, Trenton, N.J. I afterward found many at Mt. Gretna, Pa. I reported their edible qualities to Prof. Peck who wrote, September 3, 1897: “I have often wished it was edible, but it has such a disagreeable flavor when fresh that I have never ventured to eat it. I have known it to be mistaken for the common mushroom, but not eaten.” Though tough it cooks tender and is excellent. Stew and put in patties or croquettes. VI.—ORBIFOR´MES. * _Gills becoming ash-colored_. =C. di´topa= Fr. _Gr._—twofold; _Gr._—a foot. Probably from stems growing two together. =Pileus= thin, submembranaceous, convex, rarely with a small umbo, smooth, hygrophanous, brown when young and moist, grayish-white when dry. =Gills= grayish, close, thin, attached, not decurrent. =Stem= slender, equal, smooth, hollow. =Height= 1–2 in., breadth of pileus 6–18 lines. =Stem= 1–2 lines thick. Pine woods. West Albany. October. The plant has the odor and taste of new meal. I have seen no specimens with the pileus depressed. _Peck_, 23d Rep. N.Y. State Bot. =C. meta´chroa= Fr. _Gr._—changing color. Separated from C. ditopa by its thicker, depressed pileus, its thicker, less close gills, and the absence of odor. Pine woods. West Albany. October. _Peck_, 23d Rep. N.Y. State Bot. Moderately plentiful in New Jersey pines. September to October. Edible, tough; when well stewed of good flavor. ** _Gills whitish._ =C. compres´sipes= Pk.—_compressus_, pressed together; _pes_, a foot. =Pileus= thin, convex or expanded, umbilicate, glabrous, hygrophanous, brownish when moist, whitish or pale yellow when dry, margin thin. =Gills= close, subarcuate or horizontal, adnate or subdecurrent, whitish. =Stem= firm, hollow, generally compressed, slightly pruinose. =Spores= elliptical, 5–6.5×4–4.5µ. =Flesh= white when dry, odor slight, farinaceous. =Plant= gregarious, 1–1.5 in. high. =Pileus= 6–16 lines broad. =Stem= 1–2 lines thick. Grassy places. Albany. July. The moist pileus is sometimes obscurely zonate. The odor is not always perceptible unless the pileus is moist or broken. The stem is sometimes compressed at the top only, sometimes at the base only, and rarely it is wholly top-shaped. _Peck_, 33d Rep. N.Y. State Bot. Found on open lots in West Philadelphia. Though small it usually grows in troops which yield fair quantity. The caps are tender and of good flavor.
