Alteraria - Alteraria can grow indoors on a variety of substances.
Amerospores - Amerospores
are considered potential toxigenic molds. Amerospores is a general classification
for non-descript, small, round spores which are unidentifiable by direct microscopic examination and can include Acremonium,
Aspergillus, Penicillium, Verticillium, Tricoderma, Paecilomyces, Scytalidium, Cunnighamella, Monocillium, Gliocadium, and
Arthrinium - Arthrinium is a widespread fungus found on plants. It is rarely found growing indoors.
Ascospores - Ascospores are considered potential toxigenic molds. Ascospores
is a general classification for spores produced bisexual reproduction and can include Aspergillus, Penicillium, and Ascotrica. These are frequently found growing on damp substrates.
Aspergillus / Penicillium-like - Aspergillus and Penicillium are considered potential toxigenic molds. Aspergillus and Penicillium spores are indistinguishable via direct microscopic examination. Aspergillus tends to colonize continuously damp materials such as damp wallboard and
fabrics. Penicillium is commonly found in house dust, on water-damaged wallpaper,
behind paint, and in decaying fabrics.
Aureobasidium - Aureobasidium is commonly found in a variety of soils. Indoors it is commonly found where moisture accumulates, especially bathrooms and
kitchens, on shower curtains, tile grout, windowsills, textiles, and liquid waste materials.
Basidiospores - Basidiospore
is a general classification of spore that is commonly found in gardens, forests, and woodlands. They are also agents of dry, white, and brown rot.
Bipolaris / Dreschlera - Bipolaris and Dreschlera can grow on a variety of substrates.
Botrytis - Botrytis is a mold that is associated with indoor plants.
Chaetomium - Chaetomium is considered a potential toxigenic
mold. Chaetomium can be commonly found on damp sheetrock paper.
Cladosporium - Cladosporium is a common outdoor mold that can colonize continuously damp materials such as damp
wallboard and fabrics.
Curvularia - Curvularia can grow on a variety of substrates.
Epicoccum - Epicoccum tends to colonize continuously damp materials such as damp wallboard and fabrics.
Fusarium - Fusarium is considered a potential toxigenic mold. Fusarium
colonize continuously wet materials such as soaked wallboard and water reservoirs for humidifiers and drip pans.
Memnoniella - Memnoniella can be found growing on a variety of cellulose-containing
Nigrospora - Nigrospora is rarely found growing indoors.
Oidium / Peronospora - Oidium and Peronospora are plant pathogens and can not grow on indoor surfaces.
Pithomyces / Ulocladium - Pithomyces are rarely found indoors. Ulocladium
colonize continuously damp materials such as wallboard and fabrics.
Rusts - Rusts are plant pathogens and only grow on host plants.
Smuts / Myxomycetes - Smuts do not usually grow indoors. They are
parasitic plant pathogens that require a living host. Myxomycetes are occasionally
Stachybotrys - Stachybotrys is considered a potentially toxigenic
mold. Stachybotrys colonizes continuously wet materials such as soaked wallboard
and water reservoirs for humidifiers and drip pans.
Stemphylium - Stemphylium is rarely found growing indoors.
Torula - Torula can grow indoors on cellulose containing materials.
Unidentified Conidia - Unidentified Conidia are uncharacteristic fungal spores that do not lend themselves to
classification via direct microscopy.
