Melt the butter in a saucepan over medium heat, then stir in the flour and cook, stirring constantly, for 1 to 2 minutes. Add the lentil liquor and water, and continue stirring until the mixture thickens and barely begins to boil. Add the mushroom mixture, salt, and pepper, and continue stirring until the gravy begins to boil. Remove from heat and serve. *
