Sweet Gum (Liquidambar spp.)-Cankers and Diebacks

Note: There are almost no reported fungi on sweet gums in the PNW. The OSU Plant Clinic has found a few fungi that tend to be opportunistic on injured shoots and branches. Injuries may be due to such events as winter injury. These fungi include Cytospora and Nectria. The Botryosphaeria canker found in eastern and southern states has not been found in the PNW.
