Chop the mushrooms in a food processor or by hand.
In a pot, heat the olive oil over medium heat. Add the shallot and garlic, reduce the heat to low, and cook the vegetables for 3 or 4 minutes.
Add the mushrooms to the vegetables and stir well, add oregano, season with salt and pepper. Increase the heat to medium and cook for 5 minutes until the mushroom liquid releases and begins to reduce.
Add the red wine, worcerstershire sauce and cook until the mixture is nearly dry. Add the tomatoes, reduce the heat to a simmer, and cook for 30 minutes, stirring occasionally. Add the chili flakes or hot sauce. Adjust the seasoning with salt and pepper to taste, cover, and keep warm while you cook the pasta.
Bring a large pot of water to a boil. Add a large pinch of salt, add the pasta, and cook to al dente, according to the package directions.
Drain the pasta and divide it among four warmed bowls. Ladle the sauce over each portion of pasta and serve. Garnish with parmesan.
