Agaric

AG'ARIC

,
Noun.
[Gr.]
In botany, mushroom, a genus of funguses, containing numerous species. Mushrooms grow on trees, or spring from the earth; of the latter species some are valued as articles of food; others are poisonous. The name was originally given to a fungus growing on the larch. This species is now frequent in the shops, and distinguished by the name of female agaric. From this fungus is extracted a turpentine, of which three fourths of its weight is a resinous substance; the rest, a slimy, mucilaginous, earthy matter, tenacious and almost insoluble in water. It is used in dyeing, but is little esteemed in medicine.
The Agaric of the oak is called touch-wood, from its readiness to take fire.
Agaric mineral, a calcarious earth, or carbonate of lime, resembling a fungus in color and texture; found in fissures of rocks, and on the roofs of caverns. It is sometimes used as an astringent in fluxes, and a styptic in hemorrhages. It occurs in a loose semi-indurated form, white or whitish red, or yellow, light and friable. Kirwan mentions three varieties.
