One of a class of cellular, flowerless plants, (technically called Lichenes), having no distinction of leaf and stem, usually of scaly, expanded, frond-like forms, but sometimes erect or pendulous and variously branched. They derive their nourishment from the air, and generate by means of spores. The species are very widely distributed, and form irregular spots or patches, usually of a greenish or yellowish color, upon rocks, trees, and various bodies, to which they adhere with great tenacity. They are often improperly called rock moss or tree moss.
A fungus and an alga (or a cyanobacterium) living in symbiotic association.
Plant-like colonies of fungi and algae that grow on the exposed surface of rocks. Lichen grow at a constant rate within a single geographic area.
Organisms made up of algae living in the threads of a fungus. The algal cells benefit from the protection and water-retaining properties of the fungus; the fungus benefits from being able to share the food made by the photosynthesising algal cells.
the common name for any member of the group Lichenes, occurring as fungal and algae cells in symbiotic union and growing in various forms of rocks or trees (Morris 1992).
Organism comprising a species of fungus symbiotically joining with a species of algae.
A form of moss. It grows well in Arctic and northern regions. Also called caribou moss.

a forest growth that resembles scaled-down trees and bushes and is used as a scenery material.
An organism composed of a fungal mycelium within which are embedded photosynthetic algae.
Colorful, plant-like organisms that grow on rocks and other surfaces. Lichens are a symbiotic association between an algal species and a fungal species that grow together as a single organism.

a mixture of algae and fungi that grows on rocks
mutualistic symbiotic relationship of a fungus and a photosynthetic algae, functioning as a single plant. Common to rocky northern environments and a primary food for caribou. Well represented in the BWCA by several species of Reindeer Lichen ( Cladonia spp.).
a type of fungus which grows on stones
a composite plant made up of a fungus and an algae usually black, but can be gray or orange; grows slowly, often on boulders the oldest plants in the mountains - some dating back 11,000 years lichen covered boulders can be extremely slippery when wet

a descriptive term for the white, lace-like lesions that occur on the skin or mucous membrane; the cysts resemble lichen that grows on trees.
a plantlike composite consisting of a fungus and and alga
symbiotic organisms consisting of an alga and fungus important to the weathering and breakdown of rocks
A fungus that grows symbiotically (having a close relationship that benefits both objects) with algae, resulting in a composite organism that forms a crust-like growth on rocks or tree trunks.
Symbiotic association of alga and fungus. The fungus provides protection and moisture, the photosynthetic algae provide food for the fungus. Lichens are the toughest form of plant life and can live in some of the coldest and most exposed places in Antarctica as long as they have a rock to cling to. They can actively grow and photosynthesize at well below freezing point - albeit very slowly.
An algae and a fungus growing in symbiotic association on solid surfaces such as rocks or tree bark. Lichen
Lichen is a plant-like growth that is actually a result of a fungus and algae living together. It grows very slowly, lives for a long time, looks like moss or a crusty dry leaf and can grow on bare rock or soil. Lichen is an important food source for caribou.
A symbiotic association between green or blue-green algal cells and fungal hyphae
A plant that is a combination of a fungus and an alga; commonly grows on trees or rocks.
A lichen is a symbiotic association of a specific fungus and a specific alga that is so integrated functionally and morphologically that a third kind of organism is formed which resembles neither of its components. Lichens are usually classified as single "species" even though they are composed of two unrelated species. They grow on a solid surface such as rock or bark.
A composite of fungi and algae or cyanobacteria. The fungi capture and cultivate photosynthetic organisms which together provide themselves needed water and nutrients. Lichen species occur in many colors including black, brown, dark olive green, red, yellow and white.
An organism formed from the symbiotioc relationship between an algae and a fungus
n: A symbiotic relationship between a fungus and a moss. The moss does most of the work, producing sugars for the lichen's collective metabolic pathways. Lichen are generally low-growing, vary in color from bright orange or yellow to gray or black, and are often found growing on rocks and tree bark. An easy mnemonic to assist recall of the nature of a lichen's symbiosis is: "A fungus took a likin' to a moss, and now they live together."
an integrated association between either an alga or cyanobacterium with a fungus.
(lie´ kun) [Gr. leikhen: licker] • An organism resulting from the symbiotic association of a true fungus and either a cyanobacterium or a unicellular alga.

Any of a large number of small plants made up of an alga and a fungus growing symbiotically on various solid surfaces, such as rocks.
Combination of algae and fungus, appears to be an individual.
Lichens are organisms that are a symbiosis between algae and fungus. The photosynthetic algae produces food and the fungus provides protection for the algae. Lichens can survive in a variety of conditions and are found worldwide.
Lichens are symbiotic associations of a fungus with a photosynthetic partner (called a photobiont or phycobiont) that can produce food for the lichen from sunlight. The photobiont is usually either green algae or cyanobacteria. A few lichens are known to contain yellow-green algae or, in one case, a brown alga.
