Some molds can be identified by their growth patterns, but that requires an expert.  Even experts make errors based on a visual inspection, because growth patterns of different molds can appear similar to one another.  To correctly identify a mold species requires a sample that can be examined in a laboratory by an experienced technician using a microscope.

The most important thing is to remove the mold.

However, if someone has a health problem that may be caused by the mold, you may want to identify it.  Wearing rubber gloves, take a piece of scotch tape, lift some spore samples from the mold, and seal it in a Ziploc bag.  Then you have something you can take to your doctor or a laboratory.

There are lots of mold-testing laboratories available on the web.  It’s become a “hot” industry in the last couple of years.

The most common indoor molds are Cladosporium, Penicillium, Aspergillus, and Alternaria.

Some rarer molds, such as Stachybotrys, may be more dangerous but its spores are only found in two to five percent of homes and only a small percentage of those homes provide an environment for growth.
