Silver Leaf

(Chondrostereum purpureum).
Symptoms: Leaves have a silvery appearance. Infected branches have a brown discoloration in the heartwood. Infected plants die within 1-3 years.
Disease cycle: Growth of bracket-like fungus, 5-7 cm wide, emerges from dead branches and pruning wounds at plant base and releases spores. Spores are spread by wind and rain during spring and winter. It can also spread by transplants generated from stem cuttings of infected plants.
