Stachybotrys chartarum

Stachybotrys chartarum , also known as black mold or toxic black mold,[3] is a species of microfungus that produces its conidia in slime heads. It is sometimes found in soil and grain, but the mold is most often detected in cellulose-rich building materials, such as gypsum-based drywall and wallpaper, from damp or water-damaged buildings.[4][5]
