_Tricholoma melaleucum. Pers._

THE CHANGEABLE TRICHOLOMA.

[Illustration: Figure 50.--Tricholoma melaleucum. Two-thirds natural
size.]

Melaleucum, black and white; from contrasted colors of the cap and
gills.

This Tricholoma grows in abundance in northern Ohio. I have found it in
the woods near Bowling Green, Ohio. The specimens in the halftone were
found near Sandusky, Ohio, and were photographed by Dr. Kellerman. It is
usually found in sandy soil, growing singly in shady woods.

The pileus fleshy, thin, from one to three inches broad, convex, rather
broadly umbonate, smooth, moist, with variable color, usually pale,
nearly white at first, later much darker, sometimes slightly wavy.

The gills are notched, adnexed, ventricose, crowded, white.

The stem is stuffed, then hollow, elastic, from two to four inches long,
somewhat smooth, whitish, sprinkled with a few fibrils, usually
thickened at the base. The flesh is soft and white. There is no report,
so far as I know, regarding its edibility, and I have no doubt as to
this, but would advise caution.

_Tricholoma lascivum. Fr._

THE TARRY TRICHOLOMA.

Lascivum, playful, wanton; so called because of its many affinities,
none of which are very close. The pileus is fleshy, convex, then
expanded, slightly obtuse, somewhat depressed, silky at first, then
smooth, even. The gills are notched, adnexed, crowded, white; the stem
is solid, equal, rigid, rooting, white, tomentose at the base. Found in
the woods, Haynes' Hollow near Chillicothe. September and October.

_Tricholoma Russula. Schaeff._

THE REDDISH TRICHOLOMA. EDIBLE.

[Illustration: Figure 51.--Tricholoma Russula. Natural size. Caps
reddish or flesh color.]

Russula is so named because of its likeness in color to some species of
the genus Russula.

The pileus is three to four inches broad, fleshy, convex, then
depressed, viscid, even or dotted with granular scales, red or flesh
color, the margin somewhat paler, involute and minutely downy in the
young plant.

The gills are rounded or slightly decurrent, rather distant, white,
often becoming red-spotted with age.

The stem is two to three inches long, solid, firm, whitish rosy-red,
nearly equal, scaly at the apex. The spores are elliptical, 10x5u.

This plant is quite variable in many of its peculiar characteristics,
yet it usually has enough to readily distinguish it. The cap may be
flesh-color and the s
