There are three posts, only, of this, which is quite surprising here. I have seen it myself but thought nothing of it!
It is poorly recorded Worldwide http://www.gbif.org/species/5427485
It is, of course caused by a bacteria, so technically is not a Plant. I have agreed based on the photo, as it is an unusual feature, and your third picture is obviously not a natural piece of the tree arising from, say, damage.
