5 Common Types of Mold Growth

Many species of mold flourish inside of houses, particularly after water damage. Find out more about five common types of mold growth.

1. Alternaria

Alternaria grows in damp areas. Most species have a fuzzy appearance and may be black, brown or gray in color depending on conditions and the point in the growth cycle. 

2. Aspergillus

Aspergillus is a very common type of house mold, as spores tend to be more concentrated in indoor air than outdoor air. This genus favors materials containing cellulose or plant fibers. It is not uncommon to find Aspergillus growing on paper, textiles, insulation or wood exposed to high humidity. Species grow in many different colors, such as brown, black, gray, green, white or yellow. 

3. Black Mold

The scientific name of black mold is Stachybotrys chartarum. This species is not always black and may be green early in its growth cycle. Stachybotrys chartarum produces mycotoxins and is known to be one of the most dangerous types of mold. Water damage often precedes black mold growth.

4. Cladosporium 

Cladosporium tends to grow on damp building materials or textiles. This genus stands out for its ability to flourish in cooler temperatures compared to other types of mold. Cladosporium is usually black or dark green in color.

5. Penicillium

Penicillum is set apart by its blue or green color and pungent odor. This type of mold flourishes in porous materials exposed to water and is a common cause of produce spoilage. There are about 200 species of penicillum, and some are known to produce mycotoxins. 

These are five of the most common genera or types of mold found in houses and other structures. Homeowners may be able to clean up a minor infestation, but it can be difficult to determine the full extent of mold growth.
