“Black Mould” refers to stachybotrys chartarum (Stachy). Stachy is somewhat common in very warm, very humid environments – much less common where it is cooler and/or dryer. Hundreds of different moulds (and mildews) are “black.” It is impossible to identify moulds by “looking at them.” It takes a laboratory to determine the specific species. According to the Center for Disease Control ALL moulds should be removed from the indoor environments. For profesional mold rememdiation call The Professionals at PuroClean!
