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.
Widespread, cellulolytic, very commonly found on damp sheetrock paper.
Used in textile testing and the production of cellulase.
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.
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.
