The species seems related to C. expallens, but the margin of the pileus is not striate as in that fungus. The taste is very disagreeable and remains in the mouth a long time. Two persons were made ill by eating it, but their sickness lasted only about three hours. _Peck._ I have not seen this species. Its reputation is bad. Caution should be observed. V.—VERSIFOR´MES. _Pileus bright, of one color._ =C. trullisa´ta= Ellis. =Pileus= fleshy, plano-convex, at length depressed in the center, innate fibrous-scaly, becoming smoother on the disk, margin thin. =Gills= unequal, not crowded, coarse and thick, adnate with a decurrent tooth, at length white pulverulent, purple-violet at first, becoming dark brick-red. =Stem= stuffed, fibrillose, with a long club-shaped base penetrating deeply into the sand. =Spores= large, cylindric-oblong, 15–20µ. In old sandy fields. September to October. The interior of the stem in the young plant is like the gills, violet-purple, and the club-shaped base is covered with a tomentose coat, to which the sand adheres tenaciously. Related to A. laccatus and A. ochropurpureus B. Resembles the larger forms of A. laccatus, but it has a stouter habit, the pileus is more squamulose, the stem is bulbous or thickened at the base, the mycelium is violet-colored and the spores are oblong. Bull. Torrey Bot. Club, November, 1874. New Jersey, _Ellis_; New York, _Peck_, Rep. 33. Haddonfield, Watertown, N.J. Sandy soil in pine woods. _McIlvaine._ Densely cespitose. Caps and stems brown, glutinous and so incrusted with sand that it is almost impossible to clean them. Edible, but not desirable. =C. lacca´ta= Scop.—made of lac. (Plate XXIV, fig. 10, p. 82.) =Pileus= thin, fleshy, convex, sometimes expanded, even or slightly umbilicate, smooth or minutely tomentose-scaly, hygrophanous when moist, dull reddish-yellow or reddish flesh-colored, sometimes striatulate when dry, pallid or pale dull ochraceous. =Gills= broad, rather thick and distant, attached, not decurrent, flesh-colored. =Stem= slender, firm, fibrous, stuffed, equal, concolorous. =Height= 1–6 in., breadth of pileus 6 lines to 2 in. Common. June to October. An extremely variable and abundant species occurring almost everywhere throughout the season. _Peck_, 23d Rep. N.Y. State Bot. =Spores= 8–9µ _Massee_; 8–10µ _B._ Var. _pallidifo´lia_ Pk.—_pallidus_, pale; _folium_af. Gills whitish or pallid, decurrent. Var. _stria´tula_ Pk.—_stria_, a furrow. Pileus moist, smooth, thin, showing shading radiating lines, extending from near the center to the margin. In wet or damp places. A form occurs with a decidedly bulbous base. Gills appearing emarginate with a decurrent tooth.
