Dry rot
Dry rot refers to wood decay caused by certain species of fungi, also known as True Dry Rot, that digest parts of the wood which give the wood strength and stiffness. It was previously used to describe any decay of cured wood in ships and buildings by a fungus which resulted in a darkly colored deteriorated and cracked condition. In other fields, the term has been applied to the decay of crop plants by fungi and the deterioration of rubber.
