(average 5mm in thickness), multi-cellular structures which grow by tip elongation and profuse branching.A group or mass of gyphae is called the mycelium(pl. mycelia)(Figure 14.3). In conidial fungi the mycelium may take the form of a diffuse,felted metwork in a substrate, like a mouldy spot on jam. The substrate is any material on which the fungus grows,e.g. jam,orange skin,paper,leather,textile.

The hyphae secrete enzymes that digest the complex pro-teins,carbohydrates and fats of the dead organic substrates into simple amino acids,simple sugars and fatty acids.These nutrients are absorbed into the hyphae along with substrate water. The moulds or mildews which live on dead organic material are called saprophytes, in contrast to parasitic fungi which survive only on a living host.
