Bring a pot of water to a boil, enough to cover the mushrooms. Add the salt, the mushrooms and lemon juice and let them blanch for about 4 to 5 minutes. Dry them and place them in a jar. Heat the olive oil, vinegar, peppercorns, chile, and bay leaves. Pour the over the mushrooms and let them sit in the refrigerator for at least 48 hours before eating.
