A type of decay in which fungi degrade polysaccharides (cellulose and hemicelluloses) in the cell walls, creating a brown color in the decayed wood. Most common in conifers.
Predominate type of decay fungi that occurs in softwoods used above ground. Brown rot fungi attack the cellulose rather than the lignin. Brown Rot causes rapid degradation of the structural integrity and strength of logs. As the decay progresses, the wood appears to turn brown, often appearing as if it has been charred. In advanced stages, wood crumbles and voids form.
A light to dark brown decay of wood that is friable and rectangularly checked in the advanced stage; caused by fungi that attack mainly the cellulose and associated carbohydrates. Residue left is predominantly lignin.
Brown rot (Monilinia fructicola) is a fungal condition that attacks stone fruit, commonly affecting peaches, pears, apples and plums. The fruit develops small brown squishy circles, which gradually spread over the surface of the fruit. Once the fruit is entirely infected, it shrivels up and develops a fuzzy coating of fungus.
