Water Conducting Fungi

Poria incrassata is a brown rot fungus. Whereas most wood decaying fungi must rely on a water leak, or ground contact condition, to obtain the required water, poria incrassata has developed specialized root-like water-conducting tubes, called rhizomorphs, which allow it to transport water from the soil to the wood. Therefore, even in situations where wood is protected from rainfall, and no leaks exist, wood can still be decayed by poria. Once established, it can quickly spread through a building and destroy large areas of flooring and walls in as little as a year or two.
