ONYGE'NA, f. [from the Gr. onv|, unguis, hoof, and 
7 tna, generatio, birth, origin.] In botany, a genus of the 
clafs cryptogamia, order fungi. 
When Nature, on one of the days of the creation, 
madea grand diftribution of the fungi throughout the whole 
furface of the globe, (he afcribed to every family their 
refpeCtive place of birth and habitation, and ordered them 
to rife out of decayed organic matter as a laft and fhort 
memento of its tranfitory exiflence. Th efungulus under 
conlideration was allotted for it's dwelling-place the pu¬ 
trid horny fubftance of the hoofs of horfes and oxen, or 
the rotteningfeathers of ravens and crows. Such are the 
two fpecies we are to defcribe. 
1. Oxygena equina, of the horfe. From fmall heaps 
of a white mealy fubftance, this futigulus arifes, at firft 
flianelefs, and entirely covered with that dull, till it af- 
fumes the following fliape. The Hem or ftalk is gene¬ 
rally double at bottom, and fplits into two heads. The 
pcridia, or envelopes, when recent and unhurt, exhibit a 
bran-like or warty appearance, not unlike the Lycoperdon; 
but foon, this bran-like roughnefs, flattening on the fur- 
face, or adhering but loofely to it, the knob prefents a 
linocther face. The powder or pollen, feen through pow¬ 
erful Ienfes, appears mixed with evanefcent hairs, which 
are tnoft indubitably there for the purpofe of attaching 
each atom of the feed to the peridinm. - The whole head, 
with the dull, when either cut or broken, foon falls and 
dies. The time of its vegetation is fummer, and extends 
to the lateft part of autumn. It inhabits the fo ft putrid 
hoofs of horfes and cows. 
2. Onygena corvina, of the crow. Gregarious; head 
orbicular, of a tawny colour; the furface at firft granu- 
lous, afterwards inclined, naked, and pulverulent; ftein 
fmooth and round, of a whitifti colour, riling into a (len¬ 
der and conical fliape, with a flight inclination downwards. 
The height of this fungus, when young and ereft, is a 
fize fhorter than the preceding, and meafures from two to 
three twelfths of an inch : the ftalk then is fteady, rather 
thick and fhort: as it grows, the head becomes covered 
with an envelope of a farinaceous or granulpus texture r 
afterwards the ftalk rifes to the length of half an inch ; 
and the ftetn, lofing ftrength in proportion to its elonga¬ 
tion, becomes fo weak and {lender, that, unable to flip- 
port the head, it bends fenfibly downwards. The efredl 
of this is a conftant nutation.of the head, by which, when 
ripe, the duft having now loft its covering and appearing 
of a yellowifli hue, feems to hang to fucli filaments as men¬ 
tioned in the preceding fpecies. The ftetn is in general 
white ; but this colour at length affuines a pallid-reddilh 
tint, finning like filk ; it is a little ftriated, and often with 
an undulated furface. Sometimes it is deprefied and de¬ 
cumbent towards the neareft individual of the congrega¬ 
tion : it is altogether thicker than that of the O. equina;, 
although its head is nearly three times fmaller. The 
texture of the Item is fmooth, and a little fibrous. The 
interior llrufture does not differ materially from the pre¬ 
ceding. This remarkable-fpecimen was found in a place 
well (haded with trees, upon the feathers and fmall bones 
of the putrefying Skeleton oftheCorvus cornix, or hooded 
crow. They flourifn in September and OcSlober. On the 
Plate of Onchidium, &c. p.485. fig. 25 exhibitsfomein¬ 
dividuals of this fpecies in the different llages of growth, 
and of the natural fize. The fame magnified, at fig. 26.

fembling that of a finger-nail.] See the article Minera¬

eye, when it was lhaped like a finger-nail.

OOCHISRA'VA, in Hindoo mythology, *is the name 
of a many-headed horfe, that, in the fabulous legends of 
India, arofe from the ocean, when churned by gods and 
demons, as defcribed under the article Kurmavatara, 
vol. xi. p. 48. The refult of this operation was the ob¬ 
taining fourteen precious things, or gems, as enumerated 
in that article : among them the horfe, the fubjeft of this. 
That, in the infancy of fociety, the difeovery of’the va¬ 
lue of this noble animal, and of the mode of applying 
his ftrength and docility to the ufes of man, Ihould be 
the objeft of recorded gratitude, is fufficiently reafonable ; 
but, whether this be the intention of the fablein queftior., 
we cannot decide. In pi&ures of the Kurmavatara, the
