Preheat oven to 350 degrees. Butter 9-inch pie plate. Lay 1 sheet phyllo dough on clean surface. Place slightly damp kitchen towel over remaining dough to keep from drying out. With pastry brush, lightly brush with melted butter. Lay another sheet phyllo on top of buttered sheet, lightly butter. Repeat until all 8 layers are buttered, using 6 tablespoons of the butter. Place phyllo dough into the prepared pan, pressing it along bottom and sides. Trim the edges. Sprinkle walnuts over bottom of crust. In medium bowl beat together maple sugar, maple syrup, jelly, remaining 8 tablespoons butter, and eggs. Pour egg mixture over walnuts. Bake 40 to 45 minutes, or until filling is set. Serve chilled.
