Melt 1/4 cup butter or margarine in large skillet over medium heat. Add green and red peppers. Cook 2 to 3 minutes. Add mushrooms. Sprinkle with lemon juice and salt. Cook 2 minutes, stirring or tossing occasionally. Add cream and reserved crabmeat liquid. Bring to boiling. Combine melted butter or margarine and flour; blend until smooth. Stir flour mixture into cream vegetable mixture. Cook, stirring constantly, until sauce has thickened and is smooth. Add crabmeat. Simmer 1 to 2 minutes or until crabmeat is heated through. Correct seasoning to taste. Divide mixture among six shells or ramekins, or turn mixture into a 1 quart shallow baking dish. Sprinkle with grated Parmesan cheese. Place under preheated broiler (put shells or ramekins on cookie sheet for easy handling). Broil until cheese is golden brown.
