Types of direct sampling include tape lift, swab and bulk samples. What tests are used to identify white mold?Дirect mold sampling can be used to identify the species of white mold. Proper identification of the underlying cause, removal and cleanup should be performed regardless of the color of the mold growth. No area of significant mold growth within the home should be considered safe. Many molds can provoke allergic responses in sensitive individuals. Lab testing determined the growth was Acremonium. In the photo below a sample of white mold is being taken from attic sheathing. To fully identify the species or genus of mold a sample must be collected and sent to a lab for analysis.ДЄ tape lift sample is often the best method for determining the type of mold growth. This limits our ability to determine the exact type of mold by simply assessing its color. These molds can appear in everything from white or green to brown and black. Unfortunately, many types of mold such as Cladosporium and Penicillium/Aspergillus come in a variety of colors. The same is true of chaetomium and a number of other mold types. If you find white mold growth on a pair of shoes, you can rest assured it is not stachybotrys. For example, Stachybotrys is always black. However, the color can be used to rule outВ certain types of mold. To determine the specific type of mold, youвЂ™ll need mold testing.

You cannot positively determine the exact type of mold based on the color. Efflorescence is odorless, while mold growth often produces a musty odor.Д¬an color be used to identify the type of mold? Another indication, though imperfect, is the presence of a mold smell. If you find a white mold like substance on sheet rock or wood, you can certainly rule out efflorescence. Efflorescence will only occur on concrete, brick or other masonry structures. Other helpful distinguishing characteristics include the material of the substrate. Additionally, efflorescence will typically dissolve under the application of a water mist, while mold growth will not. Common areas of white mold growth include attic sheathing and crawlspace framing.ДЄ trained mold inspector can readily determine if the growth structure is from white mold or efflorescence. White mold can be found anywhere conditions conducive to mold growth are present.

This growth, while harmless, can appear very similar to white mold growth. When the water evaporates, a white, fluffy structure is left behind. Efflorescence occurs when water moves through a masonry structure, bringing unbounded salts to the surface. White mold growth provides an additional challenge because it is often confused with efflorescence, a crystalline growth structure found on concrete and masonry surfaces. How can I tell the difference between white mold and efflorescence?
