Fungi used to be considered as part of the plant kingdom, but they are though to be quite different.
The main of the fungus is a mass of tiny thread called mycelium. Fungi live on the other organic matter in the soil. Fungi are the most important agent in the breakdown of dead plant and animal material, recyvling it so that the plant can use the nutrients. Fungi live in damp areas on in water because they have no method of preventing their fragile threads dyinf out.They cannot survive dry atmospheres. There are around 50.000 species of fungi and they include yeast, rust, smuts, mildews, mould, and mushrooms.
