rly grooved and furrowed, due
probably to unequal tensions in growth. The apex in typical specimens is
rounded and blunt. It is dull white or tan color or rufescent. The flesh
is white, and very spongy, especially in age, when it is apt to be
irregularly fistulose. Figure 203 is from plants collected at Blowing
Rock, N. C., during September 1899.

There is what seems to be an abnormal form of this species figured by
Schaeffer, Table 290, which Fries separated as a distinct species and
placed in the genus _Craterellus_, one of the _Thelephoraceae_, and
called by him _Craterellus pistillaris_. This plant has been found at
Ithaca, and the only difference between this and the _Clavaria
pistillaris_ L., seems to be in the fact that in _Craterellus
pistillaris_ the end is truncate or in some specimens more or less
concave. The spores seem to be the same, and the color and general habit
of the two plants are the same. It is probably only a form of _Clavaria
pistillaris_.

=Clavaria mucida= Pers.--This is one of the smallest species of the
genus _Clavaria_. It grows on rotten wood, and appears throughout the
year. It is usually simple and clavate, but sometimes branched. The
plant is white, or yellowish, or sometimes rose color, and measures from
0.5 to 2 cm. in height, though I have usually found it from 0.5--1 cm.
in height. It is soft and watery. Figure 204 is from plants (No. 4998,
C. U. herbarium) collected at Ithaca in October, 1899.

CHAPTER XII.

THE TREMBLING FUNGI: TREMELLINEAE.

These fungi are called the trembling fungi because of their gelatinous
consistency. The colors vary from white, yellow, orange, reddish,
brownish, etc., and the form is various, often very irregular,
leaf-like, or strongly folded and uneven. They are when fresh usually
very soft, clammy to the touch, and yielding like a mass of gelatine.
They usually grow on wood, but some species grow on the ground, and some
are parasitic. The fruit surface usually covers the entire outer surface
of the plant, but in some it is confined to one side of the plant. The
basidia are peculiar to the order, are deeply seated in the substance of
the plant, rounded or globose, and divided into four cells in a cruciate
manner. From each one of these cells of the basidium a long, slender
process (sterigma) grows out to the surface of the plant and bears the
spore. A few species only are treated of here.
