Affected trees appear weak and show a general decline (A). Leaves may have upward cupping, turning prematurely yellow or reddish purple, droop, and then prematurely drop. The bark is abnormally thick and spongy and the wood underneath has a severely pitted, indented texture (B). Symptoms are most severe in the wood just above and below the soil line.
