ined to be involute, and extending beyond the gills.

The gills are attached to the stem, broadly notched as will be seen in
the specimen, closely crowded, quite entire, shorter ones numerous, a
few branched, white or whitish.

The stem is three to four inches long, thickened at the base, smooth,
firm, longitudinally grooved from which it gets its specific name,
whitish.

The spores are nearly round, 5-6u.

It closely resembles T. fuligineum but can be distinguished by the
grooved stem and crowded gills. The specimens in Figure 45 were found
near Boston, and were sent to me by Mrs. Blackford. The plants keep well
and are easily dried. They were found the first of June. They have an
excellent flavor.

_Tricholoma paedidum. Fr._

Paedidum means nasty, stinking.

The pileus is small, about one and a half inches broad, rather fleshy,
tough; convex, then flattened, soon depressed around the conical umbo;
fibrillose, becoming smooth; smoky gray, somewhat streaked; moist;
margin involute, naked.

The gills are adnexed, crowded, narrow, white, then grayish, somewhat
sinuate with a slight decurrent tooth.

The stem is short, slightly striate, dingy gray, thickened at the base.
The spores are elliptical or fusiform, 10-11x5-6u.

The specific name, "nasty" or "stinking," has really no application to
the plant. It is said to be very good when cooked. It is found in well
manured gardens and fields, or about manure piles.

It differs from T. sordidum in having no trace of violet color. T.
lixivium differs in the free truncate gills.

_Tricholoma lixivium. Fr._

Lixivium means made into lye; hence, of the color of ashes and water.

The pileus is two to three inches broad; flesh thin; convex then plane;
umbonate, never depressed; even; smooth; grayish-brown when moist, then
umber; margin membranaceous, at length slightly striate, sometimes wavy.

The gills are rounded behind and adnexed, free, soft, distant, often
crisped, gray.

The stem is about two inches long, fibrous, hollow, or stuffed, equal,
at first covered with a white down, fragile, gray.

The spores are elliptical, 7x4-5u.

The umbonate pileus and the nearly free, broad, gray gills will
distinguish it. They are a late grower and are found under pine trees in
November.
