Rhizina undulata requires a heat stimulus for the onset of pathogenicity. Slash burning after clearfelling has been a commonly accepted silvicultural practice but this often resulted in extensive mortality of newly-planted seedlings due to infection by R.
undulata. Old trees are commonly attacked by various fungal disease and decay species, notably Heterobasidion annosum and Armillaria species, which rot the heartwood and eventually leave the tree liable to windthrow, and Rhizina undulata, which may kill groups of trees following minor grass fires that activate growth of the Rhizina spores.
