GROWTH REQUIREMENTS |
|
Alternaria |
 |
Alternaria
can grow indoors on a variety of substrates. |
|
Amerospores |
 |
Amerospore 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, Cunninghamella, Monocillium, Gliocladium and some yeast.
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. Acremonium
requires very wet conditions for growth. Trichoderma grows well on paper,
wood, cloth and unglazed ceramics. |
|
Arthrinium |
|
Arthrinium is a widespread
fungus found on plants. It is rarely found growing indoors. |
|
Ascospores |
|
Ascospore is a general
classification for spores produced by sexual reproduction and can include
Aspergillus, Penicillium, and Ascotrica. Frequently found growing on damp
substrates. |
|
Aspergillus/Penicillium-like |
|
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 Drechslera can
grow on a variety of substrates. |
|
Botrytis |
|
A mold that can be found
associated with indoor plants. |
|
Chaetomium |
|
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 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 materials. |
|
Nigrospora |
|
Nigrospora is rarely found
growing indoors. |
|
Oidium/Peronospora |
|
Both of these organisms are
plant pathogens and cannot 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 found indoors. |
|
Stachybotrys |
|
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 |
|
An uncharacteristic fungal
spore that does not lend itself to classification via direct microscopy. |
