The fungus spreads by long black cords called rhizomorphs resembling bootlaces which can be found beneath the bark of infected trees, on roots or in the soil where they can travel large distances to infect other trees. This is one of the most dangerous parasites of trees, causing an intensive white rot and ultimately death; there is no cure and the fungus is responsible for large losses of timber each year.
