Material exhibiting coloration and patterns caused by fungal decay is often encountered in woodworking. The discoloration occurs as fungi colonize the wood, creating unique pigmentations and zone lines. These lines are actually defense mechanisms created by different fungal species competing for territory within the wood. Maple affected by this process, for instance, can display striking black lines against a light background.
The appeal of this type of material lies in its aesthetic qualities, offering woodworkers a distinctive visual element for projects. Historically, craftspeople have valued it for its individuality, incorporating it into furniture, musical instruments, and decorative objects. However, it is important to note that structural integrity is often compromised as a result of the fungal activity; therefore, stabilization techniques are frequently employed.
