DECAY

The decomposition of wood by fungi.
- Incipient Decay - The early stage of decay that has not proceeded far enough to soften or otherwise perceptibly impair the hardness of the wood. It is usually accompanied by a slight discoloration or bleaching of the wood.
- Advanced Decay - The older stage of decay in which destruction is readily recognized by soft, pitted, or crumbly areas. Decided discoloration or bleaching of the rotted wood is often apparent.
