Squeeze mushrooms and chop. Heat oil in heavy medium saucepan over medium heat. Add onion and sauté until tender, about 8 minutes. Add orzo and stir until coated with oil. Mix in chopped mushrooms. Meanwhile combine 4 cups broth other medium saucepan. Bring to simmer. Reduce heat to low and keep hot. Add 1 cup liquid to orzo, adjust heat so liquid simmers slowly and cook until orzo absorbs liquid, stirring occasionally. Continue adding liquid 1 cup at a time, simmering until each addition is absorbed before adding next and stirring occasionally until orzo is just tender and liquid is creamy, about 30 minutes.
