Mushrooms at the base
of the tree trunk can indicate big problems. They
can be the sign of armillaria root rot (right photo)
or other fungi which kill trees. Once you see the
mushroom like that shown on the right the decay fungus
has established itself inside the roots and trunk.
There is no cure for
this but progression of the disease may be slowed
by exposing the root collar to air by removing soil.
Prevent injury to the base of trunks to help prevent
this problem. The conks below is a sign that the trunk
is decayed. This tree was taken down because it was
ready to fall over.
