The Fungi Kingdom
Mushrooms, toadstools and moulds (molds) are multicellular fungi. Yeast is an example of a single-celled fungus.
Although some fungi such as mushrooms can be seen without a microscope, at one stage in their life cycle they cannot be seen and behave like other microorganisms. This is the spore stage.
When the spore lands in favourable conditions, the spore case breaks open and a thin thread called a hypha grows out and begins to digest any food around it. As they grow. they form a larger structure called a mycellium, which in time produces fruiting bodies, of which mushroom is an example.
A few fungi are parasites. Athlete's food is caused by a fungus that feeds on damp skin between the toes.
