ends, at first whitish and then turning a brownish color. The plants vary greatly in height and size, are sometimes cæspitose and at other times scattered. The disc in some specimens was slightly raised in the middle, almost umbonate. It was found about stumps and on the ground, at the end of May, in mixed woods. It soon withers, but does not melt into fluid.

HYPHOLOMA CAPNOIDES = smoke.
The Gray-gilled Mushroom.

Cap is reddish-brown, 1 to 3 inches broad, fleshy, convex, then flattened, obtuse, dry, smooth. The margin in our specimen was slightly revolute. Flesh white. Stem 2 to 3 inches long, 2 to 4 lines thick, growing together at the base (connate), hollow, equal, often curved, becoming silky, even, whitish at apex, and here and there striate. Gills gray color, adnate, easily separating, rather broad, waxy. The name is given on account of the smoke-colored gills. It is not common, and is generally found on or about stumps in the autumn.

HYPHOLOMA PERPLEXUM = perplexing.
The Perplexing Hypholoma.

Cap brownish and turning to yellow, 1 to 3 inches broad and slightly umbonate, flesh whitish. Stem nearly equal, 2 to 3 inches long, 2 to 4 lines thick, firm, hollow, slightly fibrillose, whitish or yellowish above, reddish-brown below. Gills thin, close, slightly rounded at inner end, at first pale yellow, then tinged with green, finally purplish-brown. Taste mild. It grows in clusters. We found it both on and around old stumps, in the woods. It is sometimes solitary. (Edible.)

COLLYBIA DRYOPHILA = oak-loving.
The Oak-loving Collybia.

Cap tan color, often varying in color, ½ inch broad, thin, convex, nearly plane, sometimes with margin elevated, irregular, smooth, flesh white. Stem equal or thickened at base, 1 to 2 inches long, 1 to 2 lines broad, cartilaginous, smooth, hollow, yellowish, or reddish like the cap. Gills narrow, crowded, adnexed or nearly free, whitish. This little mushroom we found in a thick woods late in September, growing

among dead leaves. There were oak trees all around and a great many pines. The weather had been rainy, and it was pale-colored and looked water-soaked.

TRICHOLOMA IMBRICATA = a tile.
The Imbricated Tricholoma.

Cap reddish-brown, 3 inches broad, thick, fleshy, broadly convex, and then flattened, obtuse, dry, continuous at disc, but torn into scales and fibrillose toward the margin; flesh firm, white. Stem solid, stout, sometimes short, and conico-bulbous, 1½ to 2 inches long, and as much as 1 inch thick, sometimes longer and almost equal; white at apex. Gills slightly emarginate, almost adnate, somewhat crowded, about 3 inches broad, wholly white when young, at length reddish. It grows either scattered or in groups. It is found in pine woods in September and November.
