y hours the smell becomes disagreeable. The name is given
on account of the shape of the warts, which are conspicuous.

+AMANITA VAGINATA = a sheath.+
+The Sheathed Mushroom.+

+Cap+ gray, mouse color, sometimes slate-colored gray, and even
brownish, 2 to 4 inches broad. It is thin and fragile, convex, and then
nearly flat, with a slight mound or umbo, but sometimes none. It is
deeply striate or grooved (sulcate) on the margin. +Stem+ is white and
often covered with mealy particles. It is slender, either hollow or
stuffed, 3 to 5 inches long, 1/3 to 1/2 inch thick. It is not bulbous,
but is sheathed quite high in a loose, soft wrapper, the remains of the
volva. There is no ring. +Gills+ are whitish, free from the stem, and
rounded. It is easily broken. There are several varieties (Peck). In one
the plant is white, Var. alba. In Var. livida the cap is a leaden
brownish color, and in the Var. fulva the cap is tawny yellow and
ochraceous. The mouse-colored form is the most common. We found many
specimens in July and August.

+CORTINARIUS CORRUGATUS = wrinkled.+
+The Wrinkled Cortinarius.+

+Cap+ gray, with a pinkish-yellowish tint, 2 inches broad, campanulate,
sticky, broken up into squamules, pellicle scaling, margin thin. +Stem+
slender, 5 inches long, shiny, mealy at apex, slightly bulbous. +Gills+
gray color, adnexed, distant, ventricose. This is a pretty mushroom. The
shade of color of the pileus is delicate. We found it in August in the
woods.

+BOLETUS FELLEUS = bitter.+
+The Bitter Boletus.+

This Boletus varies much in color; our plant was a brownish-gray,
a dingy color. +Cap+ 3 to 8 inches broad, convex or nearly plane,
glabrous, even, flesh white, turning to flesh or pink color when
wounded. Taste bitter, tubes adnate, long, depressed around the stem,
crowded. +Stem+ variable, 2 to 4 inches long, about 1/2 to 1 inch thick,
equal or tapering, reticulated above, bulbous or enlarged at base, a
little paler than the pileus. The Boleti we found grew in great numbers,
in different localities, and were of all sizes. The color of the
reticulations was a brownish-gray.

+BOLETUS GRISEUS = gray.+
+The Gray Boletus.+

+Cap+ dark gray, 2 to 4 inches broad, broadly convex, smooth, soft,
silky, flesh whitish. Tubes adnate, slightly depressed, mouths small.
+Stem+ 2 to 4 inches long, 3 to 6 lines thick, yellowish, much
reticulate
