Found at the base of a tree, the fruiting body is an obvious sign of infection. It is 30cm across and is a reddish brown colour on top that turns darker with age. The underside is white or cream and this is where the spores are released. The spores, which can travel great distances, can infect fresh stumps. This characteristic has important implications for forestry operations, such as thinning.
