What Is Black Mold?

Black mold is a type of fungus that grows in damp and humid environments. It begins as a microscopic spore that spreads through the air and can be found virtually everywhere. While it’s common to breathe in small amounts of mold spores, they usually don’t cause adverse symptoms in most people. However, prolonged exposure to black mold spores can lead to serious health issues. It’s important to identify and remove black mold as soon as possible to prevent further growth and potential harm to your health.

What Does Toxic Mold Look Like?

When trying to identify black mold, there are several key factors to look out for. Black mold typically appears as a dark green or black hue with a slimy or fuzzy texture. It’s commonly found in areas with high moisture content, such as bathrooms, kitchens, and basements. If you notice a musty or earthy smell in a particular area of your home, this could also be a sign of black mold. Furthermore, experiencing unexplained allergic reactions or respiratory problems may indicate prolonged exposure to black mold.

To identify black mold, pay attention to several important characteristics. It often manifests as a dark green or black hue, with a texture that may be slimy or fuzzy. Black mold thrives in moist environments, making bathrooms, kitchens, and basements common hotspots. A musty or earthy odor in certain areas of your home can also signal the presence of black mold. Furthermore, experiencing unexplained allergic reactions or respiratory problems may indicate prolonged exposure to this type of mold.

Toxic Black Mold

Stachybotrys chartarum typically appears black or extremely dark gray in color. This mold tends to have very round splotches with a speckled appearance. Often, you see darker layers of mold over lighter layers.

Black mold thrives in moist areas and at certain temperatures, so keep an eye on your kitchen, bathroom and basement. This particular mold is likely to be spotted around plumbing fixtures, under sinks, bathtubs and toilets, in crawl spaces or attics and around leaky windowsills, such as in this picture.

Sometimes, black mold may have a slightly greenish tinge, as pictured above. Black mold typically isn’t very textured, so you may first overlook it as a stain. Make no mistake, though; mold does not stain — if you have already cleaned away mold from an area and can still see dark spots or discoloration, there is still toxigenic mold on that surface.

In fact, an excellent test to help you classify toxigenic molds is a simple bleach swab. Take a cotton swab or rag, dip it in undiluted bleach and lightly dab a spot of the mold colony. If the mold seemingly disappears but quickly comes back, you are likely dealing with toxigenic mold. This is because potent molds can respond to harsh chemicals by delving deeper into the porous surfaces they grow on. Even after you’ve completely cleared a surface with bleach, those hidden spores can resurface and colonize all over again.

Different Types of Black Mold

1. Acremonium

toxic acremonium mold

This is another toxigenic mold that sometimes can be found growing alongside black mold. The problem with Acremonium is that its appearance changes over time, so it may be unrecognizable if left unchecked for too long. This mold usually starts out in small colonies that appear very wet, but eventually dry out and become powdery. You may find this mold in shades of white, gray, beige, pink or orange in color.

2. Chaetomium

toxic chaetomium mold

This toxigenic mold may appear a bit cottony, often starting out in shades of white or gray. Eventually, it may fade to brown or even black. Chaetomium is especially common in areas with constant water exposure, such as leaky roofs. It often has a musty odor and may be distinguished by its puffy, cloud-like patterns of growth. Keep an eye out for this mold on damp soil, decomposing plants and high-cellulose materials like wood and drywall.

3. Fusarium

toxic fusarium mold

Unlike some of the other molds on this list, Fusarium is both a toxigenic and allergenic mold — it’s capable of both producing mycotoxins and causing allergic reactions in people. In most cases, it should be treated as a toxigenic mold. This mold can frequently be found on rotting bards, where it can quickly and easily spread to other surfaces. Fusarium is recognizable for its distinct white, pink and red hues, as well as its cottony texture.

4. Alternaria

A surprisingly common type of outdoor mold, Alternaria is closely related to allergenic molds like Cladosporium and Penicillium. It’s easiest to find outdoors in the spring and summer, where it floats along the wind in search of a place to land. Once Alternaria spores make their way into your home, they can release mycotoxins and continue spreading into colonies. This mold is recognizable for its white, gray and brown shades, as well as having a layered appearance.

5. Trichoderma

toxic trichoderma mold

Trichoderma tends to grow on wood, paper and soil; because of this, it’s most commonly found in forests all over the world. It can be identified almost immediately by its various shades of green and fuzzy, moss-like appearance. Keep an eye out for this mold on wallpaper, drywall, painted surfaces and of course, wood.

Trichoderma can appear in a variety of shades, though it’s most commonly found in very light, cool green hues. It may also appear very foamy and have an outline of white around the edge of the colony. This is a very textured mold that is easily visible from almost any angle.

6. Apophysomyces

toxic apophysomyces mold

This is actually a specific genus of mold in the Mucor family, and while its cousins are relatively harmless, this particular type of mold is capable of releasing mycotoxins that can cause a rare but serious infection called mucomytosis. Mucor molds of almost any kind are most commonly found on decaying bards, so keep a sharp eye on any perishable items in your home and quickly discard any that develop mold growth.

toxic mucor molds

Mucor molds like Apophysomyces are usually fuzzy or fluffy, and come in a variety of white and gray shades. In some instances, they may also appear with tinges of green. Mucor molds may also have black speckles on the surface.
