I came across an interesting website, ArticleDashboard.com, which lists itself as "The Internet's premier website for article distribution." Included at the site is an article, "Are Black Molds Toxic?", by Amy A. May. I don't know her qualifications or background. However, her commentary on toxic mold is not out of the mainstream of other comments on the still controversial subject of exactly what symptoms/diseases are provoked by mold exposure:
There are very few reports that toxigenic molds found inside homes can cause unique or rare health conditions such as pulmonary hemorrhage or memory loss.
These case reports are rare, and a causal link between the presence of the toxigenic mold and these conditions has not been proven. A common-sense approach should be used for any mold contamination existing inside buildings and homes. The common health concerns from molds include hay fever-like allergic symptoms. Certain individuals with chronic respiratory disease (chronic obstructive pulmonary disorder, asthma) may experience difficulty breathing. Individuals with immune suppression may be at increased risk for infection from molds.
