Lichens
Lichens are often spoken of in the same breath as mosses, and some lichens are even called mosses, but true mosses are all distinctively green, whereas lichens appear in many vivid colors.
At one time, before the invention of aniline dyes, acids from lichens were used to make dyes, such as the purple dye orchil, the blue dye litmus, and the red dye cudbear, and they are sometimes still used that way today. Some lichens, such as oak moss, contain oils that produce fragrant odors used in scented soaps, cosmetics, and perfumes. Some lichens are also known to have antibiotic properties.fungus
and a type of algae.If you look at the lichen body through a magnifying glass, you will see that it is made up of a tangled mass of fungal strands called hyphae.
In the upper layer of these hyphae grow colonies of another type of plant.
These are most commonly green algae but are sometimes bluegreen algae.
The two types of organisms live together to the benefit of both, a relationship known as symbiosis. The fungus provides support for the algae and protects the tender algae from direct sunlight and dry air. The fungus provides moisture and minerals for the plant. The fungus also produces chemicals that, when combined with alcohol produced by the algae, form acid crystals. This acid carves tiny holes in rocks and other substances, and the fungus inserts threads (not true roots) into these holes to anchor the plant in place. The algae contain chlorophyll and synthesize sugars from carbon dioxide and sunlight, producing food for the lichens. A chemical secreted by the fungus softens the cell walls of the algae and allows nutrients to pass from the algae to the fungus.
There are many examples of symbiosis in nature, but lichens are unique because they look and behave differently from their components. The algal components of lichens can live independently and are recognizable as species that grow alone. The fungal components, on the other hand, cannot live apart from their partners. They can be placed in known families of fungi but are unlike any species that live independently.
So definite are the form, color, and characteristics of these double organisms that for hundreds of years lichens were classified as

. More than 15,000 species were named. If these organisms are classified as single species, it is difficult to fit them into the existing system of classification. But if they are classified as separate species, these fungal species that cannot live aloneseem rather strange
