There are many fungal species causing wet rot. They may cause darkening of the timber compared to the lighter parts of the timber.  Wet rot is usually found in timber in contact with the ground which has become soaked by water leakage. Wet Rot effects the strength of the timber and can severly damage the structure of a building.
