Peel and coarsely dice the shallots. Place a large pan of salted water on the stove and bring to the boil, then add the pasta.
Sauté the shallots in the olive oil and, when almost cooked through, add the wild mushrooms. Allow to cook for 1 minute and then season with salt and pepper. Add the Madeira and allow it to reduce. To this mushroom mix, now add the chopped tarragon and butter. This should form a sauce that will coat the pasta. Once the pasta is cooked, drain and add directly to the pan with the shallots and mushrooms.
Serve in bowls and grate over some fresh Parmesan.
