How Do I Identify Mold from Mildew and Yeast?

Identify mold as growing on substrates such as wood, wallboard, ceiling tiles, carpet, wall paper, paneling and leather items. Generally any cellulose or porous material will grow mold under the right conditions.

Mycologists use the term "Mildew" only for fungi that grow on plants. When mycologists say "mildew," they mean the white growth that causes diseases in plants.

"Yeast" grows naturally on habitats that are rich in carbohydrates. Examples include wet grains (rice, millets, etc), potatoes, fruits, juices, etc.

The ability to identify mold, mildew and yeast in your home is important since certain species of all three are known to pose a threat to human and animal health.
