Position a rack in the lowest part of the oven and heat the oven to 500°F.
Divide the pizza dough into two balls. On a lightly floured surface, roll one of the balls out to a 10-inch circle. Put the dough on a pizza pan or baking sheet and brush with olive oil. Bake until the dough is just beginning to color, 8 to 10 minutes.
Meanwhile, chop the mushrooms into bite-size pieces. Remove the pizza from the oven and sprinkle half of the Gruyère, mushrooms, and parsley over the pizza, leaving a 1/2-inch border. Continue to bake until the edges of the pizza are brown and the cheese is thoroughly melted, 5 to 7 minutes.
Repeat with the other half of the dough and toppings.
