Indiana--- A dangerous fungus has found its way to Indiana, and it threatens walnut trees.
The fungus causes "Thousand Cankers Disease," which is lethal to the black walnut trees found in Indiana.
It was found in Yellowwood State Forest in Brown County.
The trees aren't showing symptoms yet, but they will likely die within two or three years.
Walnut trees are typically used for walnut furniture, and of course the nuts.
If this fungus were to wipe out all of Indiana’s walnut trees it would represent a $1.7 billion loss.
