Fungi represent a very important part of the thallophytes, and are distinguished from the rest by many definite characteristics. They have no chlorophyll and no starch is present in their cells. They do not live on their own manufactured food, but rely on decaying plant or animal remains.
The fungi may be single celled plants such as yeast, which is used for baking bread anbd brewing beer or can be multi celled such as mushrooms. In these more advanced forms the main part of the plant is an intricate web of threads known as hyhae, the whole web is called mycelium. This often lives underground or inside the host plant on which the fungus is living. The hyphae threads run about either in or between the cells of the plant and have the power of dissolving the cellulose of the cell walls and living on the contents.
