| Description | Trichoderma is a filamentous fungus that is widely distributed in the soil, plant material, decaying vegetation, and wood. Hypocrea spp. are the teleomorph of some Trichoderma species. Although it is commonly considered as a contaminant, Trichoderma may cause infections in presence of certain predisposing factors. |
| Morphological definition | Septate hyaline hyphae, conidiophores, phialides, and conidia are observed. Trichoderma longibrachiatum and Trichoderma viride may also produce chlamydospores. Conidiophores are hyaline, branched, and may occasionally display a pyramidal arrangement. Phialides are hyaline, flask-shaped, and inflated at the base. They are attached to the conidiophores at right angles. The phialides may be solitary or arranged in clusters. Conidia (3 µm in diameter, average) are one-celled and round or ellipsoidal in shape. They are smooth- or rough-walled and grouped in sticky heads at the tips of the phialides. These clusters frequently get disrupted during routine slide preparation procedure for microscopic examination. The color of the conidia is mostly green |
