Short Description

This fungus-like organism is a soil-borne pathogen causing disease on many woody hosts. Primary infections in the root system result in two main types of (visible) symptoms: bleeding cankers on trunks and/or crown symptoms (little leaves, yellowing, wilting) eventually leading to chronic decline or death.
