Wash the dried porcini mushrooms and soak in water for at least 20 minutes.
Meanwhile, clean the mushrooms and cut them into slices.
Dice onion and garlic, cut spring onions into rings and sauté in a pan with butter until translucent. Drain the porcini mushrooms and sauté together with the mushrooms in the pan for approx. 5 minutes. Deglaze with white wine and let reduce. Pour in the vegetable stock, stir in the herb cream cheese, grated Parmesan and the cream and season with salt, pepper and fondor to taste. Simmer for another 5 minutes in the closed pan.
