Polyporus (Phaeolus) schweinitzii and Sparassis crispa as frequent decay fungi in Douglas fir. Of fifty, 55 ears old trees in a Pseudotsuga menziesii stand. 90% showed decay of the heart‐ wood of the butt. The possibility of transmission of the most frequent decay fungi, P. schwei‐ nitzii and S. crispa , which also are frequent parasites in the roots and butts of pine, from the roots of the Pinus sylvestris trees of the previous crop into the roots of the Douglas fir is discussed. A first identification of the fungi was made possible by storing the stem discs under moist conditions. The mycelia of P. schweinitzii and S . crispa grew out of the decayed wood and possessed a characteristic form and colour.
