Regional Notes

Western red cedar (Thuja plicata) and other conifers develop white-to-cream conks on roots and root crotches from Perreniporia subacida. Advanced decay creates stringy fibers with small black flecks. The fungus typically affects suppressed or weakened trees. Damage has been minimal; no treatment techniques are established. Favor resistant species when thinning or replanting infected sites.

Damage has not been serious enough for treatment techniques to have been developed. Remove affected trees during harvesting operations.
