What is “Black Mold”?
​

• Scientifically Speaking: "Black mold" typically refers to Stachybotrys chartarum, a type of mold that appears black or very dark green. This mold grows on materials with high cellulose content, like drywall, and requires moisture to thrive.
• Common Usage: In everyday language, "black mold" might be used to describe any mold that looks dark in color, not just Stachybotrys chartarum. This can include various species of mold that are black or dark, like Cladosporium or Aspergillus.
• Implications: The term can sometimes lead to confusion because not all black molds are Stachybotrys, and not all Stachybotrys is necessarily harmful or toxic. However, Stachybotrys chartarum is known for producing mycotoxins under certain conditions, which can be a health concern, particularly for those with allergies or compromised immune systems.
• Identification: Proper identification of mold requires more than just color assessment. Laboratory testing might be necessary to determine the exact species, especially for health or remediation purposes.

 
So, while the term, "black mold" is sometimes commonly used, for precise scientific or remediation purposes, it's better to identify the specific species of mold. If you're dealing with mold in your environment, it might be wise to consult with professionals who can perform accurate testing and advise on proper remediation.
