gonglt

An obsolete form of gang. gong2 (gong), n. [ is struck with a stick having a stuffed leather head. The tone produced is composite, and useful only for emphasis or for an overpowering noise; and the gong has been much used as an instrument of call where a far reaching sound is required, as in hotels and steamboats. Also called gong-gong. 2. A stationary bell in the form of a shallow bowl, which is struck with a hammer. gong-stand (gong's tand), n. used for suspending a Chinese gong, so that it can be sounded with convenience. goniatitid (gō-ni-at'i-tid), n. A member of the Goniatitida. Goniatitidæ (gō"ni-a-tit'i-dē), n. pl .

[ gonidi - um + -al . ] Pertaining to, of the nature of, or containing a gonidium: as, the gonidial grooves of a sea- anemone, serving to convey ova. The spores produced from the ostensible fructification in this Cla are all non-sexual or gonidial . Gonidial layer or stratum, in heteromerous lichens, the layer or stratum in which the gonidia are situated, next beneath the upper cortical layer. The colourable material in the Parmelise is found un- derneath the gonidial layer . gonidic (gō-nid'ik), a. Same as gonidial . gonidimium (gon-i-dim'i-um), n.; pl. gonidimia (-a). [NL., gonid ( ium ) + ( gon ) imium .] A go- nidioid cell that is smaller than a gonidium proper, and intermediate between a gonidium and a gonimium. Gonidimia occur in Peltigera and some other genera of lichens. To these also belong hyme- nial gonidia, which are often very minute, and are pres- ent in the thalamium. Also called lep to gonidium . See IMG:content-2494.png:[blocks in formation] gonidiose (gō-nid'i-ōs), a . [ gonidi -um + -ose .] Containing or provided with gonidia. Plants of some lower tribes, e. g., Graph ide i and Verru- car iæ, in which the thallus is but sparingly gonidiose , and the life consequently is shorter. Encyc. Brit ., XIV. 558. gonidium (gō-nid'i-um), n.; pl. gonidia (-a). [NL., γονή , generation, seed, + dim. term. -ίδιον.] 1. In algol ., a reproductive body pro- duced asexually, as a tetraspore or zoöspore. By some authors the term is made to include also the asexual reproductive bodies of fungi and other crypto- gams, being in this sense synonymous with conidium . 2. In bryol ., a cell filled with granules. Brai- thwaite .-3. One of the green or chlorophyl- bearing elements of lichens, usually occurring in the thalli in a distinct layer, but sometimes not definitely arranged. They are usually variously round- ed cells, distinct or in chains or filaments, and multiply by fi ion. They were formerly supposed to be produced by the hyphæ of the thallus at their tips; but some recent observers hold that they are formed endogenously in all parts of the lichen and its fruit; others believe that they originate entirely outside and independently of the lichen. The various forms of gonidia are found to resemble close- ly various forms of fresh-water algæ. The Schwendene- rian hypothesis a erts that the gonidia are algæ, and that the fungoid part of the lichen is a fungus parasitic upon them. Several forms have been named, as follows: (a) Eugonidia , or gonidia proper, those having a pure chloro- phyl-green color. They are subdivided into (1) haplogo- nidi a , resembling Protoccus ; (2) platy gonidia , depre ed and variously membranously connected gonidia; (3) chro- olepogonidia or chrysogonidia , which contain orange granules; (4) conferrogonidia , resembling Confervæ . (1) Gonidimia , smaller than gonidia proper, and intermediate between them and gonimia. They include hymenial go- nidi a. (c) Gonimia, which are glaucous-green or bluish. They include varieties named and characterized as fol- lows: (1) hap log on i mia , large, simple, or in small groups; (2) sirogonimia , which are scytonemoid or sirosiphonoid, tunicated, and are characteristic of Ephebacei ; (3) hormo gonimia , the commonest form, which are smaller, in mo- niliform chains, are contained in syngonimia, and occur in Collemacei ; (4) speirogonimia , like the preceding, but not moniliform, and in globose syngonimia. Also called chro- midium . Hymenial gonidia , which are often very minute, and are present in the thalamium (destitute of paraphyses) of various Pyrenocarpei. Encyc. Brit ., XIV. 556, gonimia, n. Plural of gonimium. gonimic (gō-nim'ik), a . [ gonim - ium + -ic .] Re- lating to gonimia; containing gonimia: as, the gonimic ti ue of Collema . Also gonimous .
