Saccharomyces yeasts budding.
Mycelia on wood, on bread and on a leaf.
The mycelium secretes digestive enzymes, absorbs nutrients, mates and in some species of fungi captures live animals for prey.
Mycelia can organize in a variety of ways in order to accomplish tasks. Some fungi form rhizomorphs which look like plant roots and enable the fungus to grow quickly over trees or the forest floor.
Other fungi form tight, rock-like masses called sclerotia which allow them to rest or survive difficult environmental conditions such as freezing and drying out.
In order to reproduce, mycelia form sporangia
Sexual (top) and asexual (bottom) sporangia
which produce spores.
Sporangia can be formed sexually or asexually. Spores that are produced sexually are called meiospores, for meiosis, and spores that are produced asexually are called mitospores or conidia. The sporangia in different groups of fungi have unique names. Because one mycelium is usually difficult to distinguish from another, sporangia have been a major feature used to identify and classify fungi.
