t and composed of juicy, cellular tissue. They do
not become leathery. In the genus Clavaria the fungi have no caps, but
they have stems. There are a few edible species. One can scarcely walk
any distance without seeing some species of Clavaria. They are
conspicuous, sometimes attractive looking, and interesting in their
variety.

The genus Cortinarius, one of the order of Agarics, has been already
described, but it contains so many species that it deserves especial
mention.

They are difficult to define. The genus has been subdivided by botanists
into tribes which it may be well to enumerate. We have followed
Stevenson's arrangement.

He divides Cortinarius into six tribes.

1. Phlegacium = clammy moisture. In this tribe the cap is fleshy and
sticky (viscous), while the stem is firm and dry. In all Cortinarii the
gills become cinnamon-colored. There are many large-sized mushrooms in
this tribe, the cap sometimes measuring 6 inches across.

2. Myxacium = mucous. This tribe has the stem sticky (viscous), and the
universal veil is glutinous. The cap is fleshy but thin. Gills attached
to stem and decurrent.

3. Inoloma = fibre and fringe. It contains distinguished species. The
cap is at first silky, with innate scales or fibrils, is equally fleshy
and dry. The stem is fleshy and rather bulbous.

4. Dermocybe = skin and head. The cap and stem are both thinner in this
tribe than in Inoloma. The pileus becomes thin when old, and is dry, not
moist. It is at first silky. The color of the gills is changeable, which
makes it hard to distinguish the species.

5. Telamonia = lint. Pileus moist; at first smooth or sprinkled with
superficial whitish fibres of the veil. Flesh thin, or becoming so
abruptly at the margin; the veil is somewhat double, which is a
distinguishing characteristic of this tribe.

6. Hygrocybe = moist and head. Cap in this tribe is smooth or only
covered with white superficial fibrils, not gluey, but moist when fresh,
and changing color when dry. Flesh thin.

CLASS I. GASTEROMYCETES, OR STOMACH FUNGI.

The Basidia-bearing fungi, or Basidiomycetes, are divided into three
classes, as has been already stated. The third class, Hymenomycetes, or
Membrane fungi, has been described, but there remain two other groups of
which we will now speak more fully. They may be considered too difficult
for beginners, and we would not venture to enter further into the
subject were it not that some of the most famil
