Caption: Soil fungus condiophore and conidia (Trichoderma sp.). Trichoderma is a mold that is a widespread saprobe in temperate to tropical areas commonly found in soil and wood. Trichoderma is often found in polluted waters and is found on paper, in wood construction and mineral fiber panels. This soil fungus is involved in decomposition of plant material and readily degrades cellulose. Trichoderma is reported as a type I & III allergen. Inhalation of the conidia or the microbial volatile organic compounds (mVOC) may cause symptoms similar to those of Stachybotrys reactions. It has been know to cause lung infections and peritonitis. The species Trichoderma viride is often isolated from indoor air samples and house dust. Some species are considered to be parasitic on other fungi. Ceartain species of Trichoderma can grow towards hyphae of other fungi, coil about them in a lectin-mediated reaction and degrade cell walls of the target fungi. This process (mycoparasitism) limits growth and activity of plant pathogenic fungi. This antagonistic behaviour has led to their use as agents of biological control of some fungi causing plant disease.
