Heat the remaining 1 teaspoon oil in the pan over medium-high heat. Add mushrooms and cook, stirring, until they release their juices and begin to brown, about 5 minutes. Transfer to a plate. Add garlic and wine to the pan and cook until reduced by half, 1 to 2 minutes. Stir in the reserved broth-flour mixture, lemon juice and the remaining ¼ teaspoon salt. Bring to a simmer and cook, stirring, until the sauce is thickened, about 5 minutes.
