Combine porcini mushrooms and water; let stand 20 minutes. Bring beef broth to a simmer in a medium saucepan (do not boil). Keep warm over low heat.
Heat oil in a Dutch oven over medium-high heat. Add onion; cook 5 minutes. Add shiitake mushrooms, presliced mushrooms, and garlic; cook 4 minutes. Add rice; cook 1 minute, stirring constantly. Stir in wine and porcini mushroom mixture; cook over medium heat 5 minutes or until liquid is nearly absorbed, stirring constantly. Add warm broth, 1/2 cup at a time, stirring constantly until each portion of broth is nearly absorbed before adding the next (about 20 minutes total). Stir in salt and remaining ingredients. Serve immediately.
