What is mold?
Firstly, mold is not a single organism. The term mold covers a wide variety of organisms. These all have the fact that they are fungi in common. The mold fungi create multicellular thread-like structures that are called hyphae. When most people hear the word “mold,” they immediately think of a negative. TV, television shows, and ads all claim that mold is a bad thing. But, the reality of what is mold is much more complicated than that. Mold grows from microscopic spores found in the air. These spores occasionally join together, form clusters, and become the eye-sore and potential health hazard in our homes. Most types of mold thrive in a dark and damp environment. This is why you will usually find mold in attics, basements, bathrooms, and inside walls.
Is mold a Fungus or Bacteria?
Is mold a bacteria? Nope, notta, no way. No doubt about it, It’s a fungus for sure. Bacteria have a simpler molecular structure vs fungus that has a more complex DNA make up. Bacteria will usually be unicellular, single organisms and will not generally grow in strands or clusters like fungus.

Many people eat mushrooms, a type of fungi. The yeast that we use to rise bread products is also a fungus. In fact, molds and yeasts are very similar types of fungi, except yeast is a single-cell organism and mold is a multi-cell organism. Clearly, not all fungi are bad for you and it even plays a role in the health of the environment.

Aspergillus is a name that applies to 185 different species of mold. Because of the number of species in this family, Aspergillus mold can be found in any color. But, all of these species have long flask-shaped spores. These will occasionally chain together to form long strands of Aspergillus mold on a surface.
Aspergillus niger is one of the most common types. You have most likely found this on fruit in the home. Aspergillus niger will commonly grow on fruits and vegetables and produce a black mould. This type of mould is most harmful to people with weakened immune systems.
Aspergillus fumigatus is another important mold to be aware since is the cause of 90% of aspergillus related diseases according to this report. The fungus can grow at 37 °C or 99 °F and will vary easily go airborne. This mold alone is the most important reason to keep your home mold free and clean up any contaminated area right away.
All species of Aspergillus are allergenic, but the severity depends on the type and environment of the mold in your home. Occasionally certain species of Aspergillus produce aflatoxins, which are a deadly carcinogen. So, you should get this type of mold removed immediately.
Another mold that can cause allergic reactions, Cladosporium cladosporioides is most common found on upholstery—like drapes or curtains—and carpets. This mold is usually green or brown and has a suede-like texture.
Cladosporium cladosporioides is not known to be toxic. However, you may experience allergic reactions in the eyes, nose, throat, and skin. These issues could progress to asthma attacks and lung infections if the mold is not removed.
If you’ve ever seen white, grey, or brown mold around water damage in a building, it is likely that it was caused by Chaetomium globosum. Eventually this mold changes color to black. It thrives in wet environments, and most often occurs near water damage.
If you are exposed to Chaetomium globosum you could experience skin and nail infections. Occasional Chaetomium will produce mycotoxins, so it should be removed from any building promptly.
Stachybotrys chartarum (black mold)
Probably the most dreaded mold in the United States, Stachybotrys chartarum also goes by the name “black mold.” This type of mold gets its colloquial name from the dark green to black color. It has a slimy texture, grow in moist and humid environments, and primarily grow on materials like wood, cardboard, paper, hay, and wicker.
Stachybotrys chartarum is dreaded because it is a highly toxic mold that produces mycotoxins. Symptoms of this mold include breathing problems, sinusitis, fatigue, and depression.
There are five different species of Trichoderma. All of them are white with green patches. The mold itself looks like wool balls clustered together. This type of mold is usually found on wet wallpaper and carpet.
Most of the five species of Trichoderma are non-harmful to humans. However, so may cause mild allergic reactions. Plus, it is one of the most damaging molds to structures, as it has an enzyme that destroys wood.
In medicine and food production, Penicillin is an enormously helpful mold. But, in your home it can be harmful. This is one of the easiest molds to identify, since it has a blue-green color and velvet-like texture. Like all mold, Penicillin thrives in moist environments like water-damaged buildings.
If you are exposed to Penicillin you can have respiratory symptoms. If left untreated, it can also cause pulmonary inflammation and asthma, or even chronic sinusitis.

Severe reactions may include difficulty breathing, fever, asthma attacks, and immunity problems. More mild symptoms are sneezing, coughing, and other allergic reaction signs.
But, just because you find mold in your house doesn’t mean you have to run screaming for the hills. Many mold varieties will not hurt you or cause allergic reactions in most people. Varieties that may be unsightly, but safe are Ulocladium botrytis, and Wallemia sebi.
People with extreme allergies or that are super sensitive may have mild reactions to these molds. But, the majority of the population will not have any problems. Keep in mind that mold can cause monetary as well as health damage, so you should have any mold removed even if it is of the harmless variety.
