This is a link to some pictures of "The Blob" (dark brown stuff wrapped
around the branches, about a hundred of them, three or four inches
long) which has attached itself all over my Italian Prune tree. Does
anyone know what this is and what I should do to it?

Looks like a Black Knot problem.
do some research and good luck, if it is that bad it will take a while for
the patient to recover
