The root-like tendrils of the fungus called hyphae surround and penetrate the algal cells, releasing chemicals that weaken the surrounding membrane so that the carbohydrates leak out, feeding the fungus.

In reality, the relationship frequently ranges from commensalism, where the fungus benefits but the algae do not, to outright parasitism, where the algae are harmed for the benefit of the fungus. Apothecia are rare; soralia on raised bumps in center of thallus. The lichen can also reproduce itself and looks . Some fungi consume dead plants as saprotrophs, some parasitize living organisms, and some connect to living plant roots in a mutually beneficial association called mycorrhizal (fungus root). Lichens are composed of two organisms; fungus and algae. It can also sometimes grow

They are dense toward the center, sparse and short toward the margins. lichens are useful for environmental monitoring, fungi growing as brackets on tree trunks have been used medicinally. They are dense toward the center, sparse and short toward the margins. Since fungi are heterotrophs and therefore cannot make their own food, they must rely on autotrophs that photosynthesize the suns energy to produce nutrients necessary for growth and reproduction. Common Greenshield Lichen. Yale University Press, New Haven, 795 pages. Greenshield lichens often cover broad expanses of rock and tree surfaces to the extent that long term effects come into question.

[1], According to the International Association of Lichenology, a lichen is an association of a fungus and a photosynthetic symbiont resulting in a stable vegetative body. The fungal partner is called the mycobiont and constitutes about 95 percent of the lichen body structure or thallus. He is very attentive and has been learning to identify pine trees (evergreen in winter) by finding the pine cones under them and feeling the sharp pine needles. without their algae. They are even found on Mount Everest at elevations exceeding seven kilometers. The fungus uses the algae for subsistence in like manner to a farmer tending fields to extract their bounty it would be nonsensical to assert that farmers and soybeans therefore benefit mutually in symbiosis.
