Sick Building: Fungi Release Toxin Directly Into Air, Study Finds - NBC News

 "Jean-Denis Bailly of the University of Toulouse in France and colleagues tested three common types of fungi that can grow inside buildings and found that their mycotoxins could and did disperse into the air until normal conditions.

“These toxins can subsequently be aerosolized, at least partly, from moldy material,” they wrote in their report in the journal Applied and Environmental Microbiology, published by the American Society for Microbiology.

“This transfer to air requires air velocities that can be encountered in ‘real life conditions’ in buildings.

The three species they tested were Penicillium brevicompactum, Aspergillus versicolor and Stachybotrys chartarum, all of which grew on wallpaper in their lab.

They all also produce mycotoxins."

Here's the paper:-
