_Lenzites. Fr._

Lenzites, named after Lenz, a German botanist. The pileus is corky,
dimidiate, sessile. The gills are corky, firm, unequal, branched, edge
obtuse. It is very common in the woods, sometimes almost covering stumps
and logs.

_Lenzites betulina. Fr._

[Illustration: Figure 185.--Lenzites betulina.]

Betulina, from _betula_, a birch. This has a somewhat corky, leathery
cap, firm and without zones, woolly, sessile, deeply grooved
concentrically, margin of the same color.

The gills are radial, somewhat branching, and coming together again,
sordid white or tan-color.

This species is wide-spread and is quite variable. It grows in the form
of brackets. Figure 185 was photographed by Dr. Kellerman.

_Lenzites separia. Fr._

THE CHOCOLATE LENZITES.

The pileus is corky, leathery shells, with the upper surface marked with
rough zones of various shades of brown; margin yellowish.

The gills are rather thick, branched, one running into another;
yellowish. Stem obsolete. Growing on limbs and branches, especially of
the fir tree.

_Lenzites flaccida. Fr._

FLACCID LENZITES.

[Illustration: Figure 186.--Lenzites flaccida. Two-thirds natural size.]

Flaccida means limp, flaccid. Pileus is coriaceous, thin, flaccid,
unequal, hairy, zoned, pallid, more or less flabelliform, imbricated.

The gills are broad, crowded, straight, unequal, branched, white,
becoming pallid. Spores are 5x7.

This is a very attractive plant and quite common. It runs almost
imperceptibly into Lenzites betulina. It is found on stumps and trunks.

_Lenzites vialis. Pk._

Pileus is corky, almost woody, firm, zoned.

Gills are thick, firm, serpentine.

Stem, none.

_Schizophyllum. Fr._

Schizophyllum is from two Greek words, meaning to split, and a leaf.

The pileus is fleshy and arid. The gills are corky, fan-like, branched,
united above by the tomentose pellicle, bifid, split longitudinally at
the edge. The spores somewhat round and white.

The two lips of the split edge of the gills are commonly revolute. This
genus is far removed from the type of Agaricini. It grows on wood and is
very common. _Stevenson._

_Schizophyllum commune. Fr._

[Illustration: Figure 187.--Schizophyllum commune.]

This is a very common plant, growing in the woods on branches and
decayed wood, where it can be found in both winter an
