Complete Mold Library - Common Mold Species

 

There are many different types of mold species on this Earth—some toxic, others harmless. At Mold Busters, we believe that important mold-related information should be readily available to and easily accessible by the public.

Our team has created a database of the most common species of mold found indoors so that residents of Ottawa, Montreal and surrounding areas can learn about various molds—what they look like, where they grow and how hazardous they are to human health.

Access to the mold library is FREE and extremely valuable. For more information about any of the molds listed in the library, call us and talk to a mold expert.

Alternaria


With over 250 known species , Alternaria molds are extremely common and widespread.


Alternaria

Ascospores


Ascospores are microscopic spores produced by fungal species belonging to the Ascomycota.


Ascospores

Aspergillus carbonarius


This fungal species was first described by French botanist Georges Bainier in 1916. It belongs to the Aspergillus genus of the Trichocomaceae family.


Aspergillus

Aspergillus clavatus


Aspergillus clavatus is a species of fungus that is widespread and can frequently be found growing in soil and animal manure. It is also common in cereal-based foods.


Aspergillus

Aspergillus flavus


A. flavus is the second most common species to be identified in human infection, besides A. fumigatus. In nature, it is usually found growing in soil as well as dead plants and animals.


Aspergillus

Aspergillus fumigatus


Aspergillus fumigatus is a species of fungus that causes a wide range of diseases in human beings. It is a spore-forming mold that readily grows in nature and infects a wide range of animal and plant species.


Aspergillus

Aspergillus niger


Aspergillus Niger is a type of mold and the most common fungus in the Aspergillus genus.


Aspergillus

Aspergillus ochraceus


Aspergillus ochraceus is a species of mold that is frequently found in grains, soil, and dried food products. This species produces ochratoxin A (OTA), a potent mycotoxin that can cause serious kidney damage.


Aspergillus

Aspergillus sydowii


Aspergillus sydowii is a species of fungus first described by French botanist and mycologist Georges Bainer in 1923. In nature, it is typically found in soil, on seeds and on decomposing organic matter.


Aspergillus

Aspergillus versicolor


Aspergillus versicolor is commonly found in soil and decaying organic matter, and has been known to develop on many kinds of food, including cereal grains, seeds, nuts, dried meats and dairy products.


Aspergillus

Aureobasidium


The Aureobasidium genus comprises of over 15 species or varieties. The taxonomy of the Aureobasidium genus is still an area of dispute, with species often being reclassified as varieties and vice versa.


Aureobasidium

Basidiospores


Basidiospores develop into many sorts of commonly found mold. These molds are identifiable by their MVOC (Microbial Volatile Organic Compounds) releases that have a unique musty and condensed smell.


Basidiospores

Bipolaris


Bipolaris molds are plant parasites that are majorly found in plant debris, soil, and other plant materials. They are commonly associated several crop diseases, such as leaf spots, leaf blights, melting outs, root rots and foot rots.


Bipolaris

Botrytis


The most common species of Botrytis, B.cinerea, is commonly referred to as gray mold. It first attacks a plant in the form of a white growth which over time develops into a gray mass with a velvety appearance.


Botrytis

Chaetomium


Chaetomium molds are commonly found in soil, air, dung, and plant debris. The colonies are initially cottony and white in colour but turn greyish-green as they mature. They grow quickly, feeding off of any materials that contain cellulose such as paper, fabrics and drywall.


Chaetomium

Cladosporium


Cladosporium is a common genus of fungi which can be found indoors and outdoors, growing on soil, moist surfaces or decaying organic matter.


Cladosporium

Cryptococcus


Cryptococcus is a fungus which causes cryptococcosis, especially in individuals with suppressed immune systems. It comes in sexual and asexual forms.


Cryptococcus

Fusarium


em>Fusarium is a large and economically important genus of fungi. It includes numerous species and can be found worldwide.


Fusarium

Ganoderma


Ganoderma is a fungus with herbal value, sometimes referred to as Mannentake, Reishi, or Lingzhi. The medicinal benefit of Ganoderma was first exploited in Asian countries and is fast moving to the West.


Ganoderma

Geotrichum


Geotrichum is a common fungus found worldwide. It grows on fruits, milk products, cereals, soil, air and plants. Geotrichum is also considered a normal part of human flora.


Geotrichum

Mucor


There is a tall list of Mucor mold infections and Mucormycosis is the most common among them. Also known as Zygomycosis, Mucormycosis infections refer to a wide array of ailments caused by the Mucorales gene of fungi like mucormycetes or mucor.


Mucor

Myxomycetes


The Myxomycetes, or slime molds, are a group free living amoeboid protists with complicated life cycles.


Myxomycetes

Penicillium


While Penicillium is typically non-pathogenic, there are a few exceptions. Some Penicillium species are capable of producing microbial volatile organic compounds (MVOCs) and toxins that can be harmful to human health, especially upon long-term exposure.


Penicillium

Penicillium chrysogenum


P. chrysogenum colonies are blue-green in colour with a yellowish pigment often appearing as well. However, identifying P. chrysogenum based on colour alone is not possible.


Penicillium

Poria Incrassata


Poria Incrassata differs in several important characteristics from most other building decay fungi. Its ability to attack wood of most species and to conduct water to the decay site accounts for its destructiveness.


Poria

Smuts


Smuts are characterized by the formation of dark, thick-walled spores called teliospores. There are approximately 1640 species that are regarded as ‘true’ smuts, most of them belonging to the Basidiomycota division.


Smuts

Stachybotrys


Stachybotrys is a genus of molds that can be found worldwide, in both indoor and outdoor settings. This article reviews this group of molds, their characteristics, the effects they can have on human health as well as sure ways of removing Stachybotrys mold.


Stachybotrys

Trichoderma


Trichoderma is a group of filamentous fungi typically found in soil, plants and wood.


Trichoderma

Trichophyton


Trichophyton is a collection of mold that infects the exterior of the human body, animals and soil. This means that it does not infect you internally as if only infects your hair, skin and nails.


Trichophyton

Ulocladium


Ulocladium colonies can be brown, grey or black, with a texture that resembles suede, cotton or wool. Ulocladium grows moderately fast (reaching maturity within 5 days) and typically disperses its spores by air.
