Chaetomium globosum

This fungus is isolated commonly from soil, decaying plants, seeds, food, estuarine environments and marine sediments. It has particular notoriety as a soft rot fungus and can be found on decaying wood, explaining its occurrence in indoor environments following water damage. In fact, C. globosum can be found growing on wallpaper in homes with extensive water damage. Sporulation of this fungus tends to occur more readily under dark conditions, and the spores produced are very resistant to desiccation. While not particularly allergenic itself, its presence appears to enhance the allergic response of individuals to other allergens (e.g. pollen). This species has caused invasive lung infections, subcutaneous infections and fingernail and toenail infections. The genus Chaetomium appears to be emerging as important fungal pathogens.
