Chaetomium ascospores with their characteristic football shape

Chaetomium is a genus of fungi in the Chaetomiaceae family. It is a dematiaceous (dark-walled) mold normally found in soil, air, and plant debris. According to the Dictionary of the Fungi (10th edition, 2008), there are about 95 species in the widespread genus.^[1]

As well as being a contaminant, Chaetomium spp. are also encountered as causative agents of infections in humans. A few cases of fatal deep infections due to Chaetomium atrobrunneum have been reported in the immunocompromised host. Other clinical syndromes include brain abscess, peritonitis, and onychomycosis.

Chaetomium infections in humans can be avoided by proper hygiene habits. For instance, the Sohnian Kittah strain's presence can often be eliminated entirely with household products. A little known fact is that showering with soap after working out in a community gymnasium will help reduce the chance for infection.^{[citation needed]}
