Quantity and concentration of “marker” spore types:
This score indicates the likelihood that certain distinctive types of mold present in the indoor sample originated from indoor sources. Certain types of mold are generally found in very low numbers outdoors. Consequently, their presence indoors, even in relatively low numbers compared to Penicillium, for example, is often an indication that these molds are originating from growth indoors. When present, these mold types are often the clearest indicator of a mold problem. Note, however, that the absence of marker spore types does not mean that a mold problem does not exist in a house; it just means that if a problem is present, it either involves types of mold that are more commonly found both indoors and outdoors, or that the spores from these molds were not airborne at the time of sampling.
Distribution: Stachybotrys is ubiquitous in nature. This genus contains about 15 species.
How it is spread: Stachybotrys produces wet slimy spores and is commonly dispersed through water flow, droplets, or insect transport, less commonly through the air.
Where it is found outdoors: Stachybotrys is found in soils, decaying plant debris, decomposing cellulose, leaf litter and seeds.
Where it is found indoors: Stachybotrys is common indoors on wet materials containing cellulose such as wallboard, jute, wicker, straw baskets, and other paper materials.
We recommend that you consult with an EPA certified mold mitigation company if you are not familiar with how to locate and safely remove mold growth or how to identify and correct moisture problems that may exist.
Recommend contacting a qualified mold mitigation company for further evaluation of the moderate or high levels of “Marker” spore types – Stachybotrys, that were identified in the air sample that was taken at the time of the inspection.
