Based on the pathogenicity determination, identification of morphological characteristics and SSU sequence analysis, the pathogen causing Amauroderma root rot of Acacia confusa was identified as Amauroderma rugosum (Bl.et Nees) Torrend. Biological characteristics tests showed that the optimum growth conditions were 32 ℃, pH 5, continuous illumination, D-fructose as the carbon source, and yeast extract as the nitrogen source.
