Decay fungi are living organisms which send minute threads called hyphae through damp wood, taking their food from the wood as they grow.
It most often occurs in damp timber which is in contact with, or embedded in, wet brickwork or masonry. Symptoms are: timber cracking, fruiting bodies, red dust or an acrid mushroom smell. It has been known to transport water up three storeys of a building to an area where decay is occurring.
