1 cup finely chopped white onion (1/2 large)
1/2 cup sour cream

Heat grill to medium-high. In a small bowl, whisk together 5 tablespoons oil, 1 tablespoon lime juice, and 2 teaspoons chipotle sauce; brush mixture onto both sides of mushrooms.

In another small bowl, combine remaining 2 teaspoons chipotle sauce, sour cream, and 1 tablespoon water; season with salt.
Grill mushrooms, flipping once, until charred in places, 3 to 4 minutes a side; transfer to a plate. Grill corn, turning occasionally, until charred, 6 minutes. Cut kernels off cobs; stir into onion mixture with remaining 1 tablespoon oil. Season with salt and pepper. Grill tortillas, flipping once, 30 seconds. Top tortillas with sourcream mixture, mushrooms, corn salsa, and cilantro; serve.
