Description: Phellinus tremulae (=Fomes ignarius var populinus) causes a heart rot of aspen that causes more volume loss than any other disease of aspen. Severity of the disease increases with stand age. In fact, incidence of white trunk rot is a major consideration in determining aspen rotations. Although no consistent relation exists between site and decay, generally less volume is lost in vigorous stands on good sites. On the same site, resistance to decay varies among aspen clones.
