Lichen
(gcide) | Lichen \Li"chen\ (l[imac]"k[e^]n; 277), n. [L., fr. Gr.
leichh`n.]
1. (Bot.) 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}.
[1913 Webster]
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 alg[ae]. 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 Hyph[ae], and Gonidia.
[1913 Webster]
2. (Med.) A name given to several varieties of skin disease,

enzymes common in bacteria.

the connection with the esophagus becomes elongated
into the windpipe and the inner walls of the sacs
become more and more divided, until, in the mammals,
the air spaces become minutely divided into tubes
ending in small air cells, in the walls of which the
blood circulates in a fine network of capillaries. In
mammals the lungs are more or less divided into lobes,
and each lung occupies a separate cavity in the thorax.
