We now pass to the next order, the Polyporei. We will mention four genera:
BOLETUS.
The name is that of a fungus much prized for its delicacy by the Romans, and is derived
from a Greek word meaning a clod, which denotes the round figure of the plant.
The Boleti grow on the ground, are fleshy and putrescent with central stems. The tubes are packed closely together and are easily separated.
FISTULINA = a pipe.
In this genus the tubes are free and distinct from one another. They are somewhat fleshy and grow upon wood.
POLYPORUS = many pores.
The pores or tubes in this genus are not separate from one another. They are persistent fungi, most of them growing upon wood.
