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.

His diagnosis emphasized the form of the spores, which he described as minute, sub-opaque, ovate, and agglomerated into subconcentric, water-soluble irregular clusters. He noted that the fungus adheres to paper, sometimes forming circles dotted with black. Stanley Hughes transferred the taxon to ''Stachybotrys'' in 1958.
