 Amanita phalloides has been conveyed to new countries across the Southern Hemisphere with the importation of hardwoods and conifers . Introduced oaks appear to have been the vector to Australia and South America ; populations under oaks have been recorded from Melbourne and Canberra ( where two people died in January 2012 , of four who were poisoned ) and Adelaide , as well as Uruguay . It has been recorded under other introduced trees in Argentina and Chile . Pine plantations are associated with the fungus in Tanzania and South Africa , where it is also found under oaks and poplars .
