Mold Types Glossary By ‘Mold Testing NJ-NY’

mold testing njAll spores found in indoor air are also normally found in outdoor air because most originate or live in the soil and on dead or decaying plants. Therefore, it is not unusual to find mold spores in indoor air. This Mold Glossary is only intended to provide general information about the mold found in the samples that were provided to the laboratory. ‘Mold Testing NJ-NY’ will test for these types of mold in your Bergen County NJ home and beyond. In fact, we routinely serve Hudson CountyEssex County, Union CountyPassaic County, Sussex CountyMorris County and the entire surrounding NJ and NY area!

Mold Types in NJ


Outdoor Habitat: Soil and decaying vegetation, dead and dying insects. These spores constitute a large part of the spores in the air and can be found in the air in very large numbers in the spring and summer, especially during and up to three (3) days after a rain.

Indoor Habitat: Very few of fungi that produce ascospores grow indoors. Some fungi that produce ascospores are recognizable by their spores and when observed are listed under their own categories. Wetted wood and gypsum wallboard paper.

Allergy Potential: Depends on the type of fungus producing the ascospores. Disease Potential: Not normally pathogenic as a group.

Toxin Potential: None known

Comments: Ascospores are produced from a very large group of fungi. Notable ascospores that are considered problematic for indoor environments are Chaetomium, Peziza, and Ascotricha. If these types of ascspores are observed they will be listed in the report under their own names.



Outdoor Habitat: These are mushroom spores and are common everywhere, especially in the late summer and fall.

Indoor Habitat: Very wet wood products, especially on footer plates, basements, and crawlspaces. Sometimes mushrooms can be observed growing in potted plants indoors.

Allergy Potential: Rarely reported, but some Type I (hay fever, asthma) and Type III (hypersensitivity pneumonitis) has been reported.

Disease Potential: None known

Toxin Potential: None known

Comments: This group includes wood rotting fungi, including dry rot (Serpula and Poria) that are especially destructive to buildings. However, if these types of spores (dry rot group) are observed in the sample they are listed under their own names on the report.
