When the pasta is ready, use a slotted spoon to pull it out of the water. Transfer it directly to the mushroom and pea mixture. Add a little pasta water, as necessary, to allow the pasta to move freely and easily around the pan. Allow to cook together for a minute or so to let the pasta absorb the good mushroomy flavor. Remove from heat. Stir in the Mascarpone and chives. Season with salt, as needed, and plenty of freshly ground black pepper.
