It's hard to tell but the "hanging stuff" might be spanish moss (tillandsia usenoides) which is usually common around big, humid swamps in southern USA such as the everglades.
It is in fact a small bromeliad....not a moss at all and related to the pineapple !!!
That's definitely not a willow. (Unless it's a Whomping Willow like in Harry Potter, which a tree landed in, too.) Hammerman is correct that the stuff dangling from branches is spanish moss, not the tree's own foliage.
