Dunno if this counts for this section of the site.

They look like Chi Chi's, aerial roots sometimes found on stressed Ginko 

 

Pretty cool

Inosculated aerial roots on this Arizona ash, Fraxinus velutina var loumeyi at Kew Gardens.

 

Couple of images taken 5 years apart.

 

First one was taken in May 2012 and the second image taken today by Ted Green.

Some secondary growth thickening in evidence but not as much as one would expect, even the wound wood on the pruning wound is relatively limited in terms of occlusion.

 

Perhaps a good mulching to improve the rooting environment and keep those over enthusiastic snappers a bit further away :$ :D

No idea, never been to Arizona, think I'm probably banned from the State :D

 

I have seen our native ash and other species do this though, expect it was initiated by a mechanical wound earlier in its life where cell division at the callus tissue has formed into roots.
