Combine whole-wheat flour, dry mustard, paprika, black pepper, and salt in a large ziplock bag, bowl, or paper bag.
Pour buttermilk into a separate bowl.
Dip each mushroom into the buttermilk, ensuring they are well-coated.
Place the buttermilk-coated mushrooms into the ziplock bag with the flour mixture. Shake until the mushrooms are evenly coated.
Heat vegetable oil in a deep fryer or large pot to 350°F. Fry the mushrooms in batches until golden brown and crispy, about 3-4 minutes per batch. Drain on paper towels.
