Order 4. Thelephorei, or Even Surface Fungi
In this order the lower surface of the cap is smooth and even, or slightly wrinkled. It is divided into several genera, only two of which we will enumerate, Craterellus and Stereum.
Craterellus = a Bowl
The species called the “horn of plenty,” Craterellus cornucopioides, belongs to this genus, and is often found. Stevenson says it is common. It is trumpet-shaped (tubiform). The cap is of a dingy black color, and the stem is hollow, smooth, and black. We found quite a small specimen, the pileus not more than 1½ inch broad, but it may measure 3 inches. The spore-bearing surface was of an ash color. The margin of the cap was wavy, and it was hollow right through to the base. It was only 2 inches high, and there was scarcely any stem.
Stereum = Hard
The genus Stereum is woody and leathery in nature, somewhat zoned, and looks like some Polyporci. It grows on wood, on stumps, and on dead wood.
