Excerpt from Diseases of Coniferous TreesPolyporus schweinitzii Fr. Ranks next in importance to Trametes pini in the natural forests. It commonly attacks the heartr wood of the base or butts of the trunk and of the roots of coniferous trees, especially the Douglas firs. The rot rarely extends farther up the trunk than the first saw log. The fungus spreads from diseas ed trees to healthy ones underground, where larger roots come in con tact with each other. Where this takes place it is common to find groups of trees affected with the fungus, and sometimes an entire group of Douglas firs are killed outright, In.most instances, how ever, the trees weakened by the fungus are either uprooted or broken off by the winds before death.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
