Step 1: Saute the mushrooms in 2 tablespoon butter until they loose their moisture and are just beginning to brown (about 10-12 minutes) set aside.
Step 2: In a medium saucepan cook 4 tablespoons butter and flour over medium-high heat, whisking constantly until the mixture turns a light golden color (about 6-7 minutes). Whisk in the stock and wine, stirring until the mixture thickens. Lower heat and simmer for about 12-15 minutes.
Step 3: Add in the cream, and Parmesan cheese (if using) whisk until combined, then add in sauteed mushrooms; simmer for additional 5-7 minutes, or until the sauce coats the back of the spoon. Season with salt and pepper.
