I need some help identifying it.


One point of clarification. As I said in an earlier reply, it's a
'witch's broom.' They are all caused by a mutation in a branch bud.
Nobody is sure what triggers the mutation; viruses, injury and
spontaneous mutation have all been suggested as possible causes.
Pines and spruces seem to be very susceptible to them.

An analogy would be 'cresting' in cacti.

BTW, White Pine Blister Rust doesn't look like that. Branches with
WPBR just turn brown, wither and die; they don't produce that kind of
bushy excresence.
