Trichoderma atroviride

Images of T. atroviride growing on plates show green fruiting bodies and light-responsive conidiation. In these pictures they can also be seen growing in concentric circle zones on the face of the agar (see species box image). Trichoderma species are ubiquitously described as having long filamentous hyphae and the ability to germinate on many different substrates. When the fungus grows it starts off as white, but then becomes various shades of green. Conidiophores are generally irregular in shape and number of conidia release and are also photosensitive and release when exposed to light. Finally, Trichoderma are known for their fast growth rates, and ability to colonize most substrates.

Trichoderma atroviride are fairly ubiquitous organisms, they are found in soils in both tropical and temperate locations around the world. This fungus is found on every continent, and is commonly found in Europe, North and South America and Australia (see range map). T. atroviride is a mycoparasite saprophyte, meaning it parasitizes other fungi and it obtains its food by absorbing dissolved organic matter. T. atroviride are found in many substrates including decaying wood, and fungal fruiting bodies, and are known to be able to use a wide range of substrates for carbon and nitrogen sources. Finally, T. atroviride has a wide temperature survival range from -1 to 35°C.
