Stachybotrys chartarum is also known as Stachybotrys atra; is a greenish-black colored type of mold. It commonly grows in places that have high cellulose and low nitrogen material, e.g. dust, paper, fiberboard, gypsum board and lint. Mold grows and thrives where there is excessive moisture in the air or dew resulting from water damage, humidity, water leakages, flooded zones, condensed surfaces and overflow areas. One may not have to determine the type of mold present in a place but constant moisture is needed for its growth. All molds should however be treated as same due to potential health risks.
