Ktymologically, -er-y is -r 2 (ult. -erl) with an 
abstract fem. ending.] A suffix originally of 
nouns from the French, but now used freely as 
an English formative. It U added to nouns, adjec- 
tives, and sometimes verhs, to form nouns in which the 
force of the suffix varies. Originally abstract, denoting 
the collective qualities of the subject (as In foxery, foolery, 
<iiHt*i',-ir, ho'i'ti r>i. "'if'-li'Tit, etc.), it has also or only a con- 
crete sense, as In finery, greenery, etc. In a particular 
phase of this use it denotes a business, as In Jitnery, gro- 
cery, pottery, etc.; hence It came to refer Ut wares, etc., 
collectively, as In grocery, now usually In plural yroceriei, 
ixttten/, r/VM-Avrv, etc., and to the place where such wares 
are made or sold, or to any place of business, as In grocery, 
pottery, etc., cannery, ftuhery, tannery, tripery, etc., or to 
any pUMM where the things represented by the subject are 
collected, as In/enient, pinery, rockery, etc., especially to 
places where animals are collected, or to the animals col- 
lectively, as in hennery, gootery, rnokerji, piinjery, Inujyery, 
etc. This termination easily associates with - / of what- 
ever origin, es|>ecially with -erl or --2, denoting a person 
engaged in business. Compare Jiither and Jiihery, grocer 
and grocery, putter and pottery, croeker and crockery, tan- 
ner and tannery, etc. In many cases it appears synco- 
pated as -ni. especially in the collective use, as In citizen- 
ry, Entjlighrti, yfontanry, etc.

bers being placed in Boiiiif, Chariiin being made the type 
of another family. See Eryx.

carpous pyrenomycetous fungi. Their vegetative 
jtortioii consists of a loose network of threads spread over 
the surface of the supporting leaf (or stem), appearing as 
a white mildew. Reproduction is of two kinds. Conidia 
are forme. I in chains by alistriction at the tips of erect 
hyplnc. Some of these were formerly referred to the ge- 
nns iiitl'i'ni. The sexual fruit consists of closed spheroi- 
dal peritliecia, which appear as blackish sjtecks among 
the mycelial threads. Each peritlieciiim has several or 
many appendages radiating from it, like the spokes of a 
wheel. In the genera Pndntpliirra and Microtplicero the 
appendages are dichotomously forked at the tip, often in 
a very beautiful manner. Kach p.-i itlieriiim contains from 
one to many asci, according to the genus and species to 
which it l>elongs, and the asci contain from two to eight 
>pi>ie--. Tlie principal genera are Sphaerotheca, Kn/ififilie.
