A method for the presumptive detection of the presence or absence and relative dominance of the toxic mold Stachybotrys chartarum collected from an environmental surface via a swab or other sampling device. The method of growth and color development of the sample utilizes dehydrated biological growth plates, pre measured hydration ampules, a liquid spreader press and a mold growth color key chart. The development of a characteristic shade of brown-colored mold colonies, unique to the Petrifilm(TM) YM biological growth plate, confirms the presence of Stachybotrys chartarum. The absence of the color permits the conclusion that Stachybotrys chartarum is absent in the sample. This color development method may be used to presumptively identify other molds commonly found growing on wet, building materials.
