Common in soils; A. pullulans often found indoors with damp materials in kitchens, bathrooms, and on wet frames.

Spore-forming fungi (rusts, smuts, mushrooms); elevated indoor levels can indicate water damage or high humidity.

Commonly called "lumber molds" — prevalent on freshly cut lumber used in construction.

Cellulose decomposer found on paper, plant compost, and water-damaged building materials.

The most common outdoor airborne fungus in temperate climates and a major airway allergen.

Reported to be allergenic; can cause corneal infections, mycetoma, and infections in immunocompromised hosts.

Common secondary invader in plants, soil, grains, textiles, and paper products.

Common soil fungus and mycotoxin producer; affects circulatory, alimentary, skin and nervous systems.

Closely related to Stachybotrys; produces trichothecene mycotoxins on cellulosic materials.

Common in soils and decaying organic matter; can cause mucormycosis in immunocompromised individuals.

Found throughout the environment; reported to be allergenic and linked to occupational allergy.

Wide genus, commonly found in soil samples, carpets, wallpaper, and interior fiberglass duct insulation.

Found in soil and decaying plants. Reported as an allergen; not pathogenic.

Toxigenic mold linked to infant deaths in Cleveland from pulmonary hemosiderosis associated with extensive water-damaged residences.

Reported to be allergenic. Isolated from dead plants and cellulose materials.

Cosmopolitan fungus commonly found on plant materials and water-damaged building materials such as gypsum board.
