Cercospora group (sir-ko-spore-ra)
Classification: Contaminant / Plant Pathogen
Possible Health Effect: None found at this time
Macroscopic Morphology: reddish-brown to gray-black/wooly
Environment: Plants-cause of leaf spot on sugar beets
Chaetomium (kay- toe-me-um)
Classification: Contaminant / some report allergen
Possible Health Effect: Rarely involved in systemic and cutaneous disease and sometimes reported to be allergenic. Some species can produce toxins, and there
is some research interest on whether these toxins can cause cancer.
Macroscopic Morphology: The surface of the mold is cottony, spreading and becomes tan or gray with age. With close examination the surface sometimes will
appear to have little black specks like pepper.
Environment: Chaetomium is one of the few Ascomycetes that will grow and produce spores indoors. It prefers to grow on cellulose for example paper and
wood. Primary IAQ importance is that it will grow in the same conditions as Stachybotrys (wet cellulose) and sheetrock paper. Colonies of Chaetomium and
Stachybotrys will be growing on top of one another. Also, found in soil and hay.
Cladosporium (clad-oh-spore-ee-um)
Classification: Common Allergen/ Contaminant
Possible Health Effect: Rarely pathogenic, it is a common agent of hay fever and asthma and other allergy related symptoms.
Macroscopic Morphology: Surface of the mold is greenish brown or can appear black in color with age and have heap or folded appearance.
Environment: Cladosporium can be found in most air samples most of the time. It is very common. Cladosporium is one of the types of mold found growing on
HVAC vent covers and grills. It can grow on leaves, textiles, wood, paper, and decaying vegetation.
