Fettuccine or Linguine with Mushrooms Tartufati

This dish takes its name from the fact that the mushrooms are sliced very thin, as though they were truffles. Oddly cutting the mushrooms this way also gives them a trufflelike flavor and aroma. If you are uncomfortable slicing this finely with a knife, use a plastic vegetable sheer, but be careful not to slice your fingers. If you can find them, use cremini mushrooms instead of white mushrooms.
