There is another “canker disease” of the chestnut prevalent in the
State which is entirely distinct from the blight. It is even more
important as a disease of oaks than chestnut, and is known to occur on
chestnut oak, red oak, and white oak. A _dieback_ of the chestnut is
not uncommon. Still another fungus appears to be associated with this
trouble. A _tip blight_ of the chestnut has also been found, and in
connection with it, a third species of fungus.
