excerpts from Stachybotrys chartarum: The Toxic Indoor Mold by Berlin D. Nelson, Professor, Department of Plant Pathology, North Dakota State University, Fargo
"Mycotoxin poisoning by this fungus is referred to as stachybotryotoxicosis" (read more)...
Fig. 10. Growth of S. chartarum along the base of gypsum wall board (covering the insulation on a concrete wall) inside of a ventilation tunnel around the base of an elementary school. Notice the black areas at the base of the right side wall. The spores were being drawn up into the classrooms, thus the entire gypsum wall board had to be replaced and the tunnel sanitized. The tunnel was flooded to about 6 inches deep.
Fig. 11. Growth of S. chartarum on the paper covering (arrow) of fiberglass insulation. This paper was touching the paper covering of the gypsum wall board ceiling, resulting in excessive growth of the fungus. The building had a roof leak that dripped onto the insulation and ceiling. The white ceiling is on the left. The paper is torn away from part of the fiberglass insulation.
