That almost seems the rule with C-bCs. They can occur almost anywhere. Even
in the apple tree in our Wenatchee backyard.

However, they seem to be most likely, as you suggest, in the more moist,
low level forests. The most dependable sites are those dominated by
west-side kinds of trees, hemlock and cedar. In other words, they aren't
real common in predominatly pine habitats.


I would appreciate any thoughts. Thanks.
