Appearance
Stachybotrys often has a dark greenish-black, slimy look on chronically wet materials like drywall paper, ceiling tiles, and wallpaper.
Look-Alikes
Cladosporium, Aspergillus, and other common indoor molds can also appear black or dark. Visual identification alone isn't reliable.
Confirming with Testing
Tape lift, swab, or bulk samples sent to an independent lab identify the species. This determines next steps for safe handling and remediation.
