Mushroom sauce may be made 3 days ahead and chilled, its surface covered with plastic wrap.

Spread about 1 cup sauce over pasta. Top sauce with one third of sliced mushroom mixture and half of mixed cheeses. Make 1 more layer in same manner, beginning and ending with pasta. Spread remaining sauce evenly over top pasta layer, making sure pasta is completely covered. Spread remaining sliced mushroom mixture evenly over sauce and sprinkle with reserved smoked mozzarella.
