Stachybotrys (Black Mold)
Toxic black mold associated with chronic water damage — requires professional remediation.
Stachybotrys chartarum grows on cellulose materials (drywall paper, wood) with chronic moisture. Not all black-colored mold is Stachybotrys. Professional testing (not DIY kits) identifies species. IICRC S520 governs remediation when found after water damage.
