Chaetomium

Chaetomium is a genus of yeasts. It is a dematiaceous (dark-walled) fungus normally found in soil, air, and plant debris.

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.
