=A. nardos´mia= Ellis—_nardosmius_, of the odor of nardus. (A name applied by the ancients to several plants, especially _spica nardi_—spikenard.) =Pileus= fleshy, firm, thick and compact on the disk, thin toward the margin, whitish, variegated with brown spots, with a thick, tough and separable cuticle. =Flesh= white. =Gills= crowded, subventricose, slightly emarginate, whitish. =Stem= solid, fibrous, not bulbous, sheathed below by the brown velvety veil, the ring narrow, spreading, uneven on the edge. =Spores= subglobose, 6µ in diameter. =Pileus= about 3 in. broad. =Stem= 1.5–3 in. long, 4–6 lines thick. Ground in woods, Suffolk county. September. _Peck_, 43d Rep. N.Y. State Bot. Several specimens from sandy grounds in pine woods, Haddonfield, N.J., were sent by me to Professor Peck and were identified by him. Plentiful at Mt. Gretna, Pa., September to frost, 1898. In mixed woods, on gravelly ground. Eaten in quantity by several persons. _McIlvaine._ Cuticle of caps when dry breaking up into brownish, squamulose scales, margin involute. =Gills= subdecurrent. =Veil= thick, persistent. =Stem= short, subbulbous, solid. =Flesh= white. Very much resembles a short-stemmed Lepiota. Smell and taste strong, like almonds. Disappears in cooking. III.—COLLYBIÆ. Gills adnate, stem somewhat cartilaginous. =A. mu´cida= Schrad.—_mucidus_, slimy. =Pileus= commonly shining white, thin, almost transparent, hemispherical then expanded, obtuse, more or less radiato-wrinkled, smeared over with a thick tenacious gluten; margin striate when thinner. =Stem= 1½-3 in. long, 1–2 lines thick at the apex, thickened at the base, stuffed, thin, rigid, curved ascending, smooth, white, but sooty scaly at the base when most perfectly developed. =Ring= inserted at the apex of the stem, bent downward and glued close to the stem, furrowed, the white border again erect, with a swollen and entire margin, which sometimes becomes dingy brown. =Gills= rounded behind, obtuse, adhering to the stem and striato-decurrent, distant, broad, lax, mucid, always shining white. Very variable in stature, from 1 in. (when of this size the stem is almost equal) to as much as 6 in. broad. The color of the pileus varies gray, fuliginous, olivaceous. The gills sometimes become yellow, but only from disease. Sometimes solitary, sometimes a few are joined in a cespitose manner at the base. _Stevenson._ =Spores= elliptical, 15–16×8–9µ _Massee_; 17×14µ _W.G.S._ North Carolina, _Schweinitz_, _Curtis_; Pennsylvania, _Schweinitz_; Maryland, _Miss Banning_. West Virginia mountains, 1882, Haddonfield, N.J., 1891–94, on beech trees and roots. _McIlvaine._ Commonly considered esculent in Europe. Dirt adheres so tenaciously to it that it is difficult to clean. This, however, occurs only when the fungus grows from roots and pushes its way up through covering earth. When growing from trees it is attractive and of good quality. Should be chopped fine and well cooked.
