Abstract

Decayed wood associated with Armillaria mellea was compartmentalized according to the CODIT (Compartmentalization Of Decay In Trees) model. Compartmentalization in the sapwood began after the tree walled off the area of dead cambium associated with the inflection of the fungus. The fungus spread into dying sapwood beneath and beyond the area of killed cambium, but the fungus did not spread radially outward into new wood that formed.
