In a food processor pulse quartered mushrooms until chopped fine. Add chopped mushrooms to radicchio with salt and pepper to taste and sauté, stirring, until liquid mushrooms give off is evaporated.

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

Add sliced mushrooms and sauté over moderately high heat, stirring, until golden and liquid mushrooms give off is evaporated. Stir in parsley and salt and pepper to taste.

• Pour 1 cup mushroom sauce into a baking dish, 13 by 9 by 2 inches (sauce will not cover bottom completely), and cover with 3 lasagne sheets, making sure they do not touch each other. 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.
• Cover dish tightly with foil, tenting slightly to prevent foil from touching top layer, and bake in middle of oven 30 minutes. Remove foil and bake lasagne 10 minutes more, or until top is bubbling and golden. Let lasagne stand 5 minutes before serving.
