What is wrong with my Maple Tree? (photos included)

InCentralVAJuly 18, 2013

Last year it was fine, this spring one branch looked dead and no leaves grew, now in July it looks like more branches have died, all about 20 feet up. Can anyone give us any advice on what might be causing this?
We live in Central Virginia, last couple of months have been hot but we've also had lots of storms and rain so i don't think it's from lack of water. I'm thinking maybe a disease or insect? We did notice the trunk is sometimes really dark, but it's been like that for 8+ years and leaves always showed up in spring, really nice yellow leaves in autumn. Just this year we have these dead branches and they are increasing in amount.

Have several Certified Arborists out to investigate. Then compare their opinions.

Around here, verticillium wilt can cause the same symptoms.

I actually just called my city to come check out a maple in front of my house. I believe it has verticillium wilt. My tree looks a great deal like yours.
In my research one of the big clues for wilt that my tree has - a massive overproduction of seeds slightly off season. That along with die out and rapid wilt at the crown of the tree on individual branches.
Jean's suggestion is probably a great idea. There was one other disease I saw that was similar, but it is difficult to tell which it might be without testing.

V wilt will leave dark streaks on branches and usually leave the leaves hanging on the branches, right?

I had an acer palmatum succumb to it this year and my neighbor is losing a lilac to what looks like the same. I emailed pics to an extension agent and he thought that was probably it.
