Penicillium

Penicillium is one of the most common allergenic molds in homes. Once started, it can continue to growth in ambient relative humidity of 50% or higher, such as in an average basement or in an unconditioned wall cavity. Usually green in color, high levels can be present that are invisible to the naked eye.
