Description: It is often found in plant litter, soil, and many types of plants and trees with a dark gray or black coloration. It is disseminated as a dry spore by the wind. It is not considered an allergen. It is not considered a pathogen. As a toxigenic agent, it produces trichothecenes (trichodermol and trichodermin) and griseofulvins. Trichothecene toxicity is due to the ability to bind ribosomal protein. Griseofulvin has been made commercially available as an anti-dermatophyte drug.
