Only one of these is the mold people mean when they say "black mold" — and several harmless species look exactly like it. This is why identification is a laboratory question, not a visual one. Every entry below is drawn from published mycology; each links to its Wikipedia record.

Image frames are empty pending licensed photography. Species descriptions summarise published mycological and public-health sources, including each organism's Wikipedia record. Nothing here is a diagnosis: visual identification of mold species is not reliable, which is why sampling and laboratory analysis exist.
Air and surface sampling identifies the species and the spore count, analysed by an accredited independent laboratory. Results in writing, usually within 48 hours.
Three details is all we need. A real person calls you straight back.
