While scientists have identified about 150,000 species of fungi, this is only a fraction of the several million species of fungi likely present on Earth. Organisms in this group are heterotrophic eukaryotes that eat by external digestion, then absorption. Fungi can be unicellular (yeasts) or composed of filamentous cells called hyphae, which taken together form a thallus called the mycelium.
