ked.

The stem is curt, stuffed, firm, attenuated at the base, externally
becoming even and naked. Spores 12x5-6u. _Fries._

The plant is wholly white and never large. It is easily confounded with
H. niveus and sometimes difficult to distinguish from the white forms of
H. pratensis. This plant is quite common in pastures, both in the spring
and in the fall. I found the specimens in Figure 175 on Cemetery Hill
under the pine trees on November 11. They were photographed by Dr.
Kellerman.

_Hygrophorus niveus._

THE SNOW-WHITE HYGROPHORUS. EDIBLE.

Niveus, snow-white. The plant is wholly white. The pileus is scarcely
one inch broad, somewhat membranaceous, bell-shaped, convex, then
umbilicate, smooth, striate, viscid when moist, not cracked when dry,
flesh thin, everywhere equal.

The gills are decurrent, thin, distant, acute, quite entire.

The stem is hollow, thin, equal, smooth. Spores 7x4u. Found in pastures.

_Hygrophorus sordidus. Pk._

THE DINGY HYGROPHORUS. EDIBLE.

[Illustration: Figure 176.--Hygrophorus sordidus.]

Sordidus means a dirty white, or dingy, referring to the color of the
caps, so made by adhering earth.

The pileus is broadly convex or nearly plane, glabrous, slightly viscid,
white, but usually defiled by adhering dirt; the margin at first
strongly involute, then spreading or reflexed; flesh firm when young,
tough when old.

The gills are subdistant, adnate, or decurrent, white or creamy-white.

The stem is five to ten Cm. long, firm, solid, white.

The spores are elliptical, 6.5-7.5x4-5u. _Peck._

The specimens I found were clear white, growing among leaves and were
especially free from soil. The stems were short and were inclined to be
slightly ventricose. Dr. Peck says that this "species is distinguished
from H. penarius by its clear white color, though this is commonly
obscured by the adhering dirt that is carried up in the growth of the
fungus." The young, growing plants were strongly involute but the older
plants were reflexed, giving the plants a funnel-shaped appearance and
giving the gills a much stronger decurrent appearance. Found October
26th.

_Hygrophorus serotinus. Pk._

LATE HYGROPHORUS.

[Illustration: Figure 177.--Hygrophorus serotinus.]

Serotinus means late. So called because it is late in the season.

Pileus is fleshy but thin, convex or nearly plane, often with the thin
margin curved upward, glabrous or with a few obscure innate fibrils,
reddish
