The types of molds discovered would be expected under these conditions.

Both these examples revealed a highly toxic environment from four mold types. Another example is Penicillium/Aspergillus Type Mold Spores and are usually associated with poor control of indoor humidity (see information guide and blogs). This mold often looks like the photos below:
