Types of mold
It is estimated that there are around 250,000 mold species worldwide, of which only 100,000 have been specifically identified so far. Only a few of these molds are responsible for damage to the building fabric and furnishings or health consequences for the residents in apartments and houses. Black mold, green mold, and white mold are most common in living spaces. But the yellow mold and the red mold are also relevant. These, in turn, are partly caused by different types of mold.
In order to multiply, molds need moisture and nutrition. The mold covers this nutrient substrate with a cotton wool-like coating. With a little time, such large colonies of fungi can develop. The fruiting body of the mold is responsible for the respective color. In order to determine the different types of mold, the color, structure and growth of the mold are used.

Occurrence and identifying features of the most common types of mold in living spaces
Recognize the right mold in the house:
The most common mold l is the green mold “Aspergillus fumigatus”. Its spore carriers are greenish in color, while the remaining components appear gray to whitish. This mold is found very often on food and potting soil, but also on damp walls and ceilings, and it can spread through its spores all over the home. Damp rooms such as bathrooms and kitchens, joints and poorly ventilated areas such as under the floor covering or behind wall cladding are particularly at risk from green mold. We will help you if you find green mold on the wall or something similar.
Green mold can have different consistencies, but mostly forms a fluffy coating . It is not uncommon for it to appear together with other types of mold and thus form a colorful mixture.
The poison of this mold, gliotoxin, is not extremely harmful to animals and humans, but has an immune-weakening effect. It can trigger allergies, asthma and headaches, and the spores can infect the lung tissue and cause lasting damage.
Mold test to determine the types of mold
The manifestations of the individual types of mold are not always clear. Color, consistency and shape can vary and it is easy to mix up things. The color of the mold cannot provide sufficient information about the health risk either. Exactly which mold it is can only be clarified by a trained specialist and a laboratory analysis. Only the result of the analysis provides the necessary information for the further procedure and necessary remedial measures.
In practice there are several methods of determining the specific type of mold using a mold test. First, a sample is taken to identify the mold in the house. There are several ways to take this sample. The procedure also depends on whether the mold is visible or there is suspicion of mold spores in the air. A distinction is made between contact samples, material samples, dust samples, adhesive film or contact samples, room air samples, sedimentation, particle accumulation and MVOC measurement. Sometimes several methods are used in parallel to create a report with certainty. The samples are then examined in the laboratory.
Mike Hahn, state-certified construction technician and expert for moisture and mold damage: “Whether and how dangerous a mold infestation actually is can be precisely analyzed with the help of air or material samples in the laboratory. The mold concentration in the indoor air can be measured with CFU / m³ (colony-forming units per cubic meter of room air). "
Conclusion - types of mold
Types of mold in living spaces are differently dangerous. Black mold in particular is often found indoors and can be responsible for mold allergies and numerous other diseases. If mold is discovered, the specific type should be clarified by means of a mold test in order to derive the further procedure and remedial measures.
