What is this part on my house called?

[Scott Stevens]

Hi, 

I've searched alot on Lowes and Home Depot and can't figure out what the piece of trim is that is supposed to cover the white mesh material on top of the brick mortar. It goes on top of the bricks that are about 2 feet high from the concrete ground and under the first set of vinyl siding. Behind the white mesh is wood and I don't want water to damage the area over time. 

What do you guys recommend doing?
