Hackberry bowl

I started a new bowl using Hackberry.  I secured this piece of wood through ebay, but really do not know anything about this type of wood.  Does anyone else know anything about it?  It is a light colored wood with some interesting dark markings in it and is turning very well. 

It has a great looking grain with spalting.  The bowl measures about 9 inches wide and 4 inches deep.  I will be posting it on my website as soon as I finish.  www.jaybees-crafts.com
