You ever see this somewhere in or on your house?

Places you may find wet rot: Wet rot grows on porous surfaces such as timber where there is moisture content of at least 50%. Wet rot can often lead to major structural damage if it is left to grow unchecked as it can weaken timber. Moisture content this high often is a result of defective plumbing, gutters, downpipes or stone pointing. If you spot a defective pipe then it is worth checking out your property to ensure there are no signs of growth. Fortunately, wet rot does not spread through masonry and the growth of wet rot will cease when the moisture is removed. Places you may find dry rot: Although the name dry rot suggests that no moisture is required for it to form dry rot actually requires moisture content of around 20%. A major, and important, difference between dry rot and wet rot is that dry rot will often occur in areas of the property that cannot be seen. This can lead to significant damage before the problem has been identified. These areas are often attics or underfloor areas that have poor ventilation and therefore a higher-than-normal moisture content. If you have condensation on your windows it could be an early warning sign of dry rot. DIFFERENCE IN APPEARENCE
