|Distribution||Where Found||Mode of Dissemination|
Approx. 81 species.
|Soil, seeds, cellulose substrates, dung, woody and straw materials.||Spores are formed inside fruiting bodies. Spores are forced out an opening and spread by wind, insects, water splash.|
|Allergen||Potential Opportunist or Pathogen||Potential Toxin Production|
|Not well studied.
Type I allergies (hay fever, asthma).
|Uncommon agent of onychomycosis (nail infection).||Chaetomin. Chaetomium globosum produces chaetoglobosins. Sterigmatocystin is produced by rare species. Other compounds produced (which may not be mycotoxins in the strict sense) include a variety of mutagens.|
|Growth Indoors||Industrial Uses||Other Comments|
|Widespread, cellulolytic, very commonly found on damp sheetrock paper.||Used in textile testing and the production of cellulase.||None.|
|Characteristics: Growth/Culture||Notes on Spore Trap Recognition||Notes on Tape Lift Recognition|
|Grows and sporulates on general fungal media, may need 8-20 days for fruiting body production and sporulation.||Distinctive. Chaetomium globosum has small brown "lemon" or "football-shaped" ascospores.||Distinctive and readily identifiable on tape lifts.|
