The term 'Wet Rot' is often used to describe most fungi other than dry rot and is confined to wet timbers only. Wet rot fungus has no facility to colonise any surrounding timbers or other building materials.
Timbers affected by wet rot are normally joist ends and wall plates in contact with damp masonry. The most common forms of wet rot are :- cellar fungus (Coniophora puteana), white pore (Fibroporia vaillantii) and white rot (Donkioporia expansa).
Treatment of timbers affected by wet rot decay is often limited to the replacement of badly decayed timbers in conjunction with the localised application of preservative fluids or pastes. New timbers should be isolated from contact with the damp masonry and if possible, works should be undertaken to dry the wall to prevent decay in the future.
