Abstract
The fungi colonizing Pseudotsuga menziesii (Douglas-fir) sapwood lumber were assessed in sam- ples collected from locations in western Oregon. A total of 547 isolates representing 29 genera and 45 species were obtained from sample boards. Graphium spp. represented 17% of all isolates, and the inci- dence of these species increased with time after saw- ing. The addition of streptomycin to malt extract agar improved isolation frequencies, while the addi- tion of cycloheximide sharply limited isolations to Graphium spp. and some Trichoderma isolates. The results indicate that Douglas-fir sapwood is suscepti- ble to colonization by a variety of fungal species. As a result, control strategies that concentrate on one fungus may have limited success because of interfer-
