It produces mycotoxins that can irritate skin and mucous membranes. One potent mycotoxin produced by Stachybotrys is called satratoxin; it is also toxic when inhaled. Extreme care should be taken when this organism is amplified indoors.

Staphylococci Opportunistic pathogen. It can survive and grow in nasal secretions and on skin. It produces many toxins that contribute to pathogenicity. Coagulase positive are considered potentially pathogenic. Streptomyces Generally non-pathogenic. Some species can cause infections in humans. It also produces potentially harmful mycotoxins.

It is also an allergen and may infect immunocompromised individuals.

Ulocladium Isolated from soil, wood, and decaying plant material, Ulocladium grows on very wet walls and particleboard. Because of its high water requirements, it is considered an excellent indicator of water damage. This genus is allergenic, contributing to the allergy load especially in those with Alternaria allergy.

Wallemia Found worldwide in house dust, air samples, dry foodstuffs and soil. Wallemia attacks materials with low water activity is an allergen and may produce mycotoxins.
