What Is Stachybotrys?

Stachybotrys Description and Natural Habitats

Stachybotrys (also known by its nicknames of  “black mold”, “toxic black mold”, “toxic mold”, and “Stachy”, and sometimes misspelled as Stachybotris) is a filamentous fungus occasionally isolated as a mold contaminant from nature and indoor environments. The geographic distribution of Stachybotrys is widespread. Stachybotrys mold spores and mold growth has been discovered in contaminated grains, tobacco, insulator foams, indoor air, and water-damaged buildings.  (from http://www.doctorfungus.org)

An extensive survey of indoor and outdoor S. chartarum air concentrations by geographical regions in the United States found S. chartarum in 6% of the 1,717 buildings sampled in the period 1996-1998  (46% offices,  18% schools, 13% hospitals, 4% homes, 0% industrial sites, and 18% other). http://ntp.niehs.nih.gov/ntp/htdocs/chem_background/exsumpdf/stachybotrys.pdf

Stachybotrys is a greenish black mold that, when active and growing in a wet environment can look black, shiny, glistening and/or slimy.

Stachybotrys grows on material with a high cellulose content or such as hay, straw, wicker, and wood chips, as well as building materials such as ceiling tile, drywall, paper vapor barriers, wallpaper, insulation backing, cardboard boxes, paper files, fiberboard, the paper covering of gypsum wallboard, particleboard, jute, dust, and wood when these items become water damaged.

Stachybotrys mold requires very wet or high humid conditions for days or weeks in order to grow. Most mold spores can begin growing after just 24 hours of wetness, whereas Stachybotrys spores take at least 48 hours of sustained wetness to begin growth. 

Thus, Stachybotrys survives and grows best in a continually wet environment such as a slow water leak in a wall, or in a building suffering from ongoing high humidity levels. Excessive indoor humidity resulting in water vapor condensation on walls, plumbing leaks, spills from showering or bathing, water leaking through foundations or roofs may lead to growth of many types of mold, including Stachybotrys. 

Because Stachybotrys spores are rarely airborne (unless Stachy mold growth is dry and disturbed or the mold spores are attached to airborne dust or other airborne particulates), Stachy is usually identified by direct swabs, or lift tape samples of the mold itself with laboratory analysis of the collected physical samples.

People can be exposed to  S. chartarum via  dermal  contact, ingestion, and inhalation.  For the general population, the most common reports of exposure  involve water-damaged buildings,  including  homes,  office buildings, courthouses, hospitals, a hotel, and schools.  Exposures leading to stachybotrytoxicosis have been reported among farmers, workers at facilities processing malt grain  or  reprocessing  moldy grain, textile mill workers using plant fibers, and workers at binder twine factories.

Stachybotrys mold growth produces trichothecene mycotoxins known as satratoxins, and these toxins may lead to pathological changes in animal and human tissues, resulting in serious health and medical problems. Medical studies about the health effects of Stachybotrys mold include---

Other Mold Species that Produce Potent

Mycotoxins of the Type Produced by Stachybotrys


Many fungi (e.g., species of Aspergillus, Penicillium, Fusarium, Trichoderma, and Memnoniella) in addition to Stachybotrys
chartarum can produce potent mycotoxins, some of which are
identical to compounds produced by Stachybotrys chartarum.
Mycotoxins are fungal metabolites that have been identified as toxic agents. For this reason, SC cannot be treated as uniquely toxic in
indoor environments. (Courtesy of New York City Health Dept.)


Stachybotrys Species names

The genus Stachybotrys has a single well-known species, Stachybotrys chartarum.
Additional species names include:

  • Stachybotrys alternans (obsolete) 
    This obsolete species is a synonym of
     S. chartarum 
  • Stachybotrys atra (obsolete) 
    This obsolete species is a synonym of
     S. chartarum 

Stachybotrys chartarum 
S. alternans
 is an obsolete synonym of this species.
S. atra
 is an obsolete synonym of this species. 

As seen in the pictures below, Stachybotrys mold is characterized by clusters of colourless to brown swollen phialides at the tips of colourless to brown, sometimes branched, conidiophores. The dark brown 1-celled spores (conidia) are produced successively from the tips of the phialides and collect in wet masses. Species with spores in chains are referred to Memnoniella. A strong decomposer of cellulose and thus usually associated with decaying plant materials. Pictures are courtesy of Botany Department, University of Toronto
