Memnoniella is often mistaken for stachybotrys when seen by the naked eye. This is understandable being that certain species of Memnoniella were classified as the more well-known and feared mold. A main difference between the two molds is that Memnoniella produces spores that are normally in chains, while Stachybotrys generally produces its spores in a mass.

Memnoniella is distributed worldwide that is commonly found isolated in soil. It can grow on most cellulose containing materials. This would include decaying plant material, paper, wallpaper, and textiles.

In homes, Stachybotrys can be observed as a very dark green or black growth.  It grows well on surfaces that are high in fiber content (cellulose) as a constant nutrient source.  Wallpaper, wood, ceiling tiles and carpet are some common places where the mold is seen growing.  Very wet areas are the ideal habitat for it to grow as well.  It is commonly recognized as a water damage indicator.  Houses that have had substantial water damage such as flooding are the perfect condition for the mold to grow and spread.  Even after growth begins, it still needs consistent and abundant moisture to grow.

The species chartarum, in its own right, is a mold known to produce very toxic mycotoxins.  A mycotoxin is simply a toxic chemical produced by molds.  These mycotoxins produced can be detrimental to the health of human beings.  Molds in general can have adverse effects, but the effects of this genus are the worst known.  The effects of exposure to Stachybotrys can span from an acute breathing difficulty to ultimately the death of a human being.  Some initial symptoms of exposure can be:  coughing, sneezing, difficulty breathing, irritated skin, sore throat etc.  Exposure can also cause more serious health problems such as seizures, memory loss, infertility, and sometimes a miscarriage.  There have also been cases where people have died due to excessive exposure.
