Stachybotrys chartarum

Stachybotrys chartarum is the quintessential black mold found in indoor environments. It is distributed worldwide, primarily found associated on decaying plant material. S. chartarum possesses a battery of enzymes linked to plant decomposition, making it a potent attacker of all forms of wood, paper and natural fibers (e.g. wool). Hence, it is commonly an indicator of moisture problems in homes and can be found growing on paper, wallpaper, wall board, wood and textiles. S. chartarum is not a common pathogen, in and of itself, but has garnered particular attention for its role in Sick Building Syndrome, due to its high production of mycotoxins (satratoxin G and H). Long-term exposure to such toxins can induce a myriad of health maladies, including nausea, dermatitis, rhinitis, depression, general malaise, headaches, sore throats, etc. S. chartarum has also been known to invade lung tissue.
