What do the mucor and penicillus mushrooms have in common?

Mukor and penicillus are allergenic forms of mold. They both cause a range of health problems, especially those related to the respiratory system. When exposed, asthma may develop or existing asthma conditions may worsen. They also cause breathing difficulties and flu symptoms, including fever and malaise. These types of mold are common in water damaged homes and buildings. They are found in places like carpets, wallpaper, air ducts and even mattresses. They quickly spread from one area of the house to another.
