Stachybotrys chartarum, commonly known as black mold, is a type of fungus that thrives in damp, humid environments. It typically grows on materials rich in cellulose, such as wood, paper, and drywall. This mold is often associated with water damage and can be found in buildings with poor ventilation or high moisture levels. Exposure to Stachybotrys chartarum can lead to health issues, particularly in individuals with respiratory problems or weakened immune systems. Symptoms may include coughing, sneezing, and skin irritation. Proper remediation and moisture control are essential to prevent its growth and protect indoor air quality.
