Wood-decaying fungi

Wood-decaying fungi are a type of fungi that feed on cellulose and lignin. They can cause extensive damage to wood, reducing its strength and making it hazardous.


 * Types of wood-decaying fungi: The most common types are brown rot and white rot. Historically, wood decay fungi have been divided into soft rot, brown rot, and white rot based on the morphology and colouring of the decayed wood.


 * Identification: Many wood decay fungi can be identified by the distinctive shape, colour, and texture of the fruiting bodies they form on trees. These fruiting bodies take several forms, depending upon the fungus that produces them, but most of them fit into categories commonly referred to as mushrooms, brackets, or conks.


 * Damage: Wood decay can make trees hazardous, as infected trunks and limbs cannot support their weight and fall, especially when stressed by wind, heavy rain, or other conditions. Decay can also be hidden, affecting wood strength without any outward sign of its presence.


 * Moisture content: Wood-decaying fungi require a moisture content higher than the Fiber Saturation Point (FSP) of the wood species upon which they rest, typically between 27% and 30% . Dry wood won’t decay, and if you add water to dry wood, it goes to satisfy the need for walls, which absorb water.


 * Prevention: To prevent wood-decaying fungi, it is important to keep wood dry and well-ventilated . Moisture control is key to preventing wood decay, so it is essential to fix any leaks or other sources of moisture in the home.
