Abstract: The fungus Heterobasidion annosum (Fr.) Bref. (= Fomes annosus (Fr.) Karst.) causes a root and butt rot of conifers in many temperate parts of the world. The decay, called annosus root rot, often kills infected conifers; infected trees that survive grow more slowly and are susceptible to windthrow and bark beetle attack.
