Chaetomium elatum

About

Chaetomium elatum is a very common and widely distributed saprotrophic fungus of the Chaetomiaceae family of molds which has been found to grow on many different substances all over the world. It was first established by Gustav Kunze after he observed it growing on dead leaves. Its defining features that distinguish it from other Chaetomium species are its extremely coarse terminal hairs and the lemon-shaped morphology of its ascospores. It produces many metabolites with potential biotechnology uses including one with promise against the rice blast disease fungus, Magnaporthe grisea. It shows very little pathogenic ability causing confirmed disease in only a few plant species.
