Usage examples of "endothia".
By the time scientists identified the source as an Asian fungus called Endothia parasitica, probably introduced with a shipment of trees or infected lumber from the Orient, the chestnuts were dead and the fungus had escaped into the great sprawl of the Appalachians, where one tree in every four was a chestnut.
The problem arises when a tree encounters an attacker for which evolution has left it unprepared, and seldom has a tree been more helpless against an invader than the American chestnut against Endothia parasitica.
