nt is dry it is well to moisten the fingerbowl or bell-glass
on the inside before placing it over the mushroom. The spores of Boleti,
and, indeed, all fungi can be caught and fixed in the same way.

From the study of these spore-prints we shall find five different colors
of spores. This family is, therefore, divided into five series,
determined by the color of the spores, which are always constant in
color, size and shape.

The five series will be treated in the following order:

1. The white-spored Agarics.
2. The rosy-spored Agarics.
3. The rusty-spored Agarics.
4. The purple-brown-spored Agarics.
5. The black-spored Agarics.

=ANALYTICAL KEY.=

This key is largely based upon Cooke's analytical key. Its use will help
to locate the plant in hand in the genus to which it belongs.

The first thing the student should do is to determine the color of the
spore if it is not evident. This is best done according to the plan
described on page 15.

The plant should be fresh and mature. Careful attention should be given
to different stages of development. The habit of the plant should be
considered; then, as soon as the color of the spores is determined, it
will be an easy matter to locate the genus by means of the key.

GROUP I--HYMENOMYCETES.

Mycelium floccose, giving rise to a distinct hymenium, fungus fleshy,
membranaceous, woody or gelatinous. Spores naked.

Hymenium, normally inferior--
Hymenium with gills Agaricaceae.
Hymenium with pores Polyporaceae.
Hymenium with teeth Hydnaceae.
Hymenium even Thelophoraceae.
Hymenium, superior--
Hymenium on smooth surface, club-shaped, Clavariaceae.
Hymenium lobed, convolute, gelatinous, Tremellaceae.

FAMILY 1--AGARICACEAE.

Hymenium inferior, pileus more or less expanded, convex, bell-shaped.
Gills radiating from the point of attachment of the pileus with the
stem, or from a lateral stem to other parts of the cap, simple or
branched.

I. Spores white or slightly tinted.
_A._ Plants fleshy, more or less firm, decaying soon.
_a._ Stem fleshy, pileus easily separating from
the stem.
Volva present and ring on the stem.
Pileus bearing warts or patches free from the
cuticle Amanita.
Volva present, ring wanting Amanitop
