Rhizoids penetrate food, absorb nutrients and anchor the

mycelia of zygomycetes.

Lichens are especially sensitive to airborne pollutants and

will often die when air pollution levels rise in an area. The

fungus provides a dense web of hyphae in which algae or

cyanobacteria can grow. The fungal tissues account for

most of the mass of lichen.

Mycelia are dense masses of hyphae. Dense masses of

hyphae comprise the main body of a lichen.

Mycorrhizae are a mutualistic relationship involving a

fungus and a plant. This type of relationship is essential for

the growth of orchids.

The fairy rings engage in a circular cycle of feeding on dead

plant material, growing, using up available nutrients, killing

both the grass and the mushrooms, leaving this material to

be available once again to the growth of the grass.
