LICHEN

n.[L. from Gr. ] 1. In botany, the name for an extensive division of cryptogamian plants, constituting a genus in the order of Algae, in the Linnean system, but now forming a distinct natural order. They appear in the form of thin flat crust, covering rocks and the bark of trees, or in foliaceous expansions, or branched like a shrub in miniature, or sometimes only as a gelatinous mass, or a powdery substance. They are called rock moss and tree moss, and some of the liverworts are of this order. They also include the Iceland moss and the reindeer moss; but they are entirely distinct from the true mosses (Musci. )
2. In surgery, a species of impetigo, appearing in the form of a red, dry, rough, and somewhat prurient spot, that gives off small furfuraceous scales.

Webster's 1913 Dictionary

LICHEN

Li "chen, n. Etym: [L., fr. Gr.

 

1. (Bot. )

 

Defn: 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.

 

Note: A favorite modern theory of lichens (called after its inventor the Schwendener hypothesis ), is that they are not autonomous plants, but that they consist of ascigerous fungi, parasitic on algæ. Each lichen is composed of white filaments and green, or greenish, rounded cells, and it is argued that the two are of different nature, the one living at the expense of the other. See Hyphæ, and Gonidia.

 

2. (Med. )

 

Defn: A name given to several varieties of skin disease, esp. to one characterized by the eruption of small, conical or flat, reddish pimples, which, if unchecked, tend to spread and produce great and even fatal exhaustion.

lichen

li chen |ˈlīkən ˈlaɪkən | ▶noun 1 a simple slow-growing plant that typically forms a low crustlike, leaflike, or branching growth on rocks, walls, and trees. Lichens are composite plants consisting of a fungus that contains photosynthetic algal cells. Their classification is based upon that of the fungal partner, which in most cases belongs to the subdivision Ascomycotina, and the algal partners are either green algae or cyanobacteria. Lichens obtain their water and nutrients from the atmosphere and can be sensitive indicators of atmospheric pollution. 2 [ usu. with modifier ] a skin disease in which small pimples or bumps occur close together. DERIVATIVES li chened adjective lichen ( sense 1 ), li chen ol o gy |ˌlīkəˈnäləjē |noun lichen ( sense 1 ), li chen ous |-nəs |adjective lichen ( sense 2 ) ORIGIN early 17th cent.: via Latin from Greek leikhēn.
