Grassy ground. Gouverneur, St. Lawrence county. September. _Mrs. Anthony._ _Peck_, 50th Rep. N.Y. State Bot. Edibility not tested. =A. pubes´cens= Schw.—downy. =Pileus= yellow, covered with a thin pubescence, margin involute. =Stem= short, about 1 in. in length, at first white becoming yellowish, bulbous, bulb thick. =Volva= evanescent. =Gills= white. In grassy grounds. Rare. North Carolina, _Schweinitz_, _Curtis_. =A. agglutina´ta= B. and C.—viscid. =Pileus= 1–2 in. broad, white, hemispheric then plane, viscid, areolate-scaly from the remains of the volva, margin thin, sulcate. =Stem= .5–1.5 in. long, 2 lines thick, short, solid, bulbous. =Volva= with a free margin. =Gills= broad, ventricose, rotundate-free. =Spores= elliptic. In pine woods. North Carolina, _Curtis_. Resembling some of the dwarf forms of A. vaginata but at once distinguished by its solid stem and decidedly viscid, areolate-squamose pileus. Am. Jour. Sci. and Arts, 1848. [Illustration: Grouped by F.D. Briscoe—Studies by C. McIlvaine. PLATE XII.] FIG. PAGE. FIG. PAGE. 1. LEPIOTA AMERICANA, 48 3. LEPIOTA CEPAESTIPES, 46 2.

[Illustration: SECTION OF LEPIOTA PROCERA.] =Pileus= _generally scaly_ from the breaking up of the cuticle and the adherence of the concrete veil. =Gills= free, often very distant from the stem and attached to a _cartilaginous_ collar. =Stem= hollow or stuffed, its flesh distinct from that of the pileus. =Ring= at first attached to the cuticle of the pileus, often movable, sometimes evanescent. On the ground. Several are found in hot-houses and hot-beds, and are probably introduced species. The universal veil, covering the entire plant when very young, is closely applied to the pileus, which from the breaking up of the cuticle is generally scaly. The =stem= in most species differs in substance from the pileus. This is readily seen by splitting the plant in half from cap to base. It is easily separated from the cap, leaving a cup-like depression therein. =Gills= usually white. In some species they are yellow-tinted. In others they become a dingy red when wounded or ageing. The veil in this genus, being concrete with the cuticle of the pileus, never appears as loose warts or patches, neither is there a volva as in Amanita and Amanitopsis. These three genera are the only ones in the white-spored series having gills free from the stem. In a few species the gills are slightly attached to the stem, but are never decurrent upon it as in Armillaria. When the plant is young it is egg-shaped. It then gradually spreads, becomes convex, and opens until it is nearly flat, with a knob in the center.
