1,200+ genera


Microscopic View Basidiospores Mold

Where would I normally find this type of mold?

Ubiquitous, Cosmopolitan. Distributed by wind and released during periods of high humidity or rain.

Where does it grow outside?

Gardens, forests and woodlands.

Where does it grow inside?

Dry rot, wood rot and brown rot are all the result of basidiospores producing fungi.  However, in the vast majority of cases, basidiospores detected in air samples are not from indoor growth.  They are typically brought in through windows and doors.  Because of this, mold remediation is typically not required.

Is this “black mold”?

The term black mold (also “toxic black mold”) is not scientific but is widely used by the media to usually reference Stachybotrys molds.

Health Concerns

Is it a potential allergen?

Some of people may experience hay fever, asthma, Lycoperdonosis and mushroom culture hypersensitivity.

Does it present any unique human risks? (as pathogen, opportunist or contaminant)*

Some reports have shown this to be the cause of opportunistic infections.

Can it produce toxins?**

Poisoning (toxicosis) is usually attributable to ingestion of mushrooms that produce the following toxins: amanitins, monomethyl-hydrazine, muscarine, ibotenic acid, and psilocybin.


Can it be identified via Air Sampling?


Can it be identified via Direct Sampling?

Rarely identified except when sampling area of dry rot, wood rot or brown rot.

What are some of its industrial uses?

One species (A. pullulans) produce pullulan which is a biodegradable polysaccharide processed into fibers and used for packaging food and drug products.

Other comments:

Some mushrooms are non wood rotting and should be submitted to laboratory for accurate identification.
