F.U.S. Fungus of Unusual Size Traditional Cache

You won't even need to get dirty on this one, but you might have to touch a large fungus.

Up on a mound, and under a tree, is the biggest dang mushroom you ever did see.  It was placed to celebrate a big Four Oh which is not old and not young, but the middle you know.  So park near the farmstand, and have a nice stop, then find the huge mushroom and pull up its top.
