While this species looks similar to the medication Penicillin, they are not one and the same. Penicillium is the fungi (mold) used to produce the standard antibiotic. Still, it is first processed through an in-depth fermentation process with sugar and other additives to become the desired pharmaceutical. Penicillium itself is an allergen mold that appears bluish-green and grows with a velvet-like texture. Unlike the antibiotic form, Penicillium in the home can cause respiratory distress, pulmonary inflammation, trigger asthma, and cause chronic sinusitis. This mold spreads quickly and is commonly found on water-damaged buildings, furniture, carpets, and even insulation.


Mucor is another allergenic fungus that is found in households. Mucor grows as a white or gray colored thick patch of mold and spreads quickly. Invading moisture ridden areas such as HVAC ducts, air condition units, and old or damp carpeting, Mucor thrives near moisture from condensation. This mold species can cause Asthma and flu-like symptoms. Mucor is also known to grow into severe cases of infestation, causing Mucormycosis. This fungal infection can cause severe damage to the eyes, nose, sinuses, lungs, and even brain. Mucor is a highly dangerous mold and should not be handled by anyone other than a mold professional.


Found in carpets, wallpapers, and fabrics, this mold species also naturally occurs on food and is known to spread rapidly. Appearing as pink, white, or red, Fusarium is an allergen and toxigenic as a mold species. Initial exposure is known to cause skin infections and allergic responses such as sore throat, runny nose, itchy eyes, and sneezing. However, prolonged exposure can result in life-threatening conditions such as bone infection or brain abscess. These toxins can damage the nervous system and eventually lead to hemorrhaging and internal bleeding. If you believe you have seen, or have symptoms of this mold type, call a professional expert at IMold immediately for proper remediation.


Acremonium is a toxigenic mold strain that begins as a pink, grey, orange, or white small moist mold and eventually becomes a powdery mold substance. Acremonium typically breeds within internal home systems. Humidifiers, cooling coils, drain pans, and window sealants are all highly common growth areas. Acremonium is also known to accompany Stachybotrys (also known as black mold). Exposure of this toxic fungus can include risks of bone marrow, and immune system diseases, as well as the risk of impaired brain function.


Stachybotrys is the infamous toxic black mold. Dark green or black, this slimy mold can appear in various damp places in the home. Typically the areas affected have been wet or humid for weeks.  Black Mold thrives on wood, cardboard and wicker. These materials are found within wall structures as well as outside, such as cabinetry. Kitchen, bathroom, and Laundry room cabinetry are a familiar complaint for black mold growth. Known to most, exposure to this mold can cause severe health issues, from troubled breathing, sinusitis, and fatigue, to depression. Children and infants have also been reported with neurological illnesses and pulmonary hemorrhage (bleeding from the lungs).
