Dry Rot

wood-rot

Dry rot is wood decay caused by certain species of fungi 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.

The life-cycle of dry rot can be broken down into four main stages. Dry rot begins as a microscopicspore which, in high enough concentrations, can resemble a fine orange dust. If the spores are subjected to sufficient moisture they will begin to grow fine white strands known as hyphae. As the hyphae germinate they will eventually form a large mass known as mycelium. The final stage is afruiting body which pumps new spores out into the surrounding air.

In other fields, the term has been applied to the decay of crop plants by fungi and the deterioration of rubber.
