obis_, a trench, and _ferro_, to bear,
referring to the pitted condition of the stem. The pileus is convex,
centrally depressed, more or less zoned, reddish-yellow, viscid, the
margin very much incurved, downy.

The gills are adnate, or slightly decurrent, whitish, and often very
much curled, because of the incurved condition of the cap at first.

The stem is equal, stuffed, adorned often with pits of a darker color.

The spores are white, juice white, then yellowish.

The plant is very acrid to the taste, and solid. Too hot to be eaten. I
have found it only a few times on the hills of Huntington township, near
Chillicothe. The yellowish hue and markedly incurved margin will
identify the plant. Found in August and September.

_Lactarius trivialis. Fr._

[Illustration: Figure 134.--Lactarius trivialis. One-half natural size.
Caps light tan with a pinkish hue. Very acrid.]

Trivialis means common.

The pileus is three to four inches broad, usually damp or watery,
sometimes quite viscid, shining when dry, convex, then expanded,
depressed in the center, margin at first incurved, even, smooth; warm,
soft tan, rather light, and sometimes a very slight pinkish hue
prevails. The flesh is solid and persistent.

The gills are rather crowded, slightly decurrent, at first whitish,
then a light yellow, many not reaching to the stem, none forked. The
stem is from three to four inches long, of same color as the pileus,
often a much lighter shade; tapering from the cap to the base, smooth,
stuffed, and finally hollow. The plant is quite full of milk, white at
first, then turning yellowish.

The plant is very acrid and peppery. It is quite plentiful along the
streams of Ross county, Ohio. It is not poisonous, but it seems too hot
to eat. It is found after rains from July to October, in mixed woods
where it is damp.

_Lactarius insulsus. Fr._

[Illustration: Figure 135.--Lactarius insulsus. One-third natural size.
Caps yellowish or straw color. Very acrid.]

Insulsus, insipid or tasteless. This is a very attractive plant. Quite
solid and maintains its form for several days; The pileus is two to four
inches broad, convex, depressed in the center, then funnel-shaped,
smooth, viscid when moist, more or less zoned, the zones much narrower
than L. scrobiculatus, yellowish or straw-color, margin slightly
incurved and naked.

The gills are thin, rather crowded, adnate and sometimes decurrent, some
of them forked at the bas
