In a 5- to 6-quart pan over high heat, bring 3 to 4 quarts water to a boil. Add orecchiette and cook, stirring occasionally, until barely tender to bite, 15 to 18 minutes.
Meanwhile, rinse and drain zucchini blossoms; reserve about four blossoms for garnish. Pull petals from remaining blossoms and cut lengthwise into quarters; discard tough stem ends and other parts.
Pour 2 tablespoons olive oil into a 10- to 12-inch frying pan over medium-high heat; when hot, add garlic and porcini and stir just until mushrooms are limp and liquid is evaporated, 5 to 6 minutes. Stir in herbs and remove from heat.
Drain pasta, reserving 1 cup cooking liquid, and return to pan. Add mushroom mixture, along with tomatoes, quartered zucchini blossoms, remaining 1/4 cup olive oil, and salt and pepper to taste. Mix gently over medium-low heat until warmed through, 5 to 7 minutes. If pasta is too dry, add reserved cooking liquid as desired. Spoon into wide, shallow bowls and garnish portions with reserved whole zucchini blossoms. Top with parmesan curls if desired.
