Top three common household molds include
Aspergillus, Cladosporium, and Stachybotrys chartarum/atras.
Aspergillus is responsible for illness such as Aspergillosis and many allergy symptoms. It is typically shades of grey,green and sometimes yellow. It is found in any oxygen based environment and reproduces A-sexually.
Cladosporium is some of the most common indoor and outdoor mold species. Species produce olive-green to brown or black colonies, and have dark-pigmented conidia that are formed in simple or branching chains. Many species of Cladosporium are commonly found on living and dead plant material. It is easily airborne and can grow anywhere moisture is present.
Stachyborys chartarum or s. atras is known as “black mold” or “toxic black mold” in the U.S., and are frequently associated with poor indoor air quality that arises after fungal growth on water-damaged building materials. According to the Center for Disease Control and Prevention, “The term ‘toxic mold’ is not accurate because while this mold produces dangerous mycotoxins, the actual mold itself is not toxic.
