Mold is a fungus that has many species. It lives inside and outside of al structures; it is found naturally everywhere. Not all molds are toxic. Many are harmful, but only a few types of mold can cause potentially serious injury. Most simply cause the symptoms similar to that of seasonal allergies. Some, however, can cause illnesses such as pulmonary edema, brain damage, and emphysema. In some case of prolonged exposure, death may result. The most indoor molds are Cladosporium, Aspirilligus, Stachybotrys, Fusarium, Penicillium, and Alternaria.

Stachbotrys

Most commonly recognized as the most dangerous mole family, stachybotrys is often what people are referring to when they speak of black mold. It is the most dangerous of the molds species, stachybotrys chartarum. Spores from this particular mold produce myotoxins which can are toxic to humans if inhaled, eaten, or touched. It is black, slimy, and found in areas that have been exposed to standing water for lengthy time period. It grows on materials that are rich in cellulose, such as sheet rock, wall paper, insulation, and ceiling tiles.

Cladosporium, Fusarium, Alternaria and Penicillium

All three of these dangerous mold families can be found in soil; on dead plants; cellulose rich materials such as sheet rock, insulation or fabric; water damaged carpets; and grain—among other things. These types of mold are very dangerous if allowed to colonize in a home. Fusarium and Cladosporium can also grow in ductwork that is lined with fiberglass.

Asperilligus

Asperilligus grows in the same type of environment as the other four mold families. It is the most common of the black mold group. It feeds on the many of the same materials as the rest of the common indoor mold group.

All of these species are found naturally either indoors or outdoor. To avoid contracting illness from any of these black molds, you must take precautions. Eliminate any standing water, and get rid of any old building materials, and dead plants. Also, never try to test any mold. Call the local health department or a licensed professional for suspected mold problem.
