Gen. LXXXYI. MUCOR, Mich.
Flocci tubulosi, fértiles erecti, terminati sporangio membranaceo dehiscente (raro diffluente) includente
sporidia discreta.
The species of this genus are developed upon all sorts of decajing substances. The vesicular heads, which do
not coUapse, as in Jacopliora, distinguish the genus. Little is known of exotic forms. (Name from the Latin
mucor; a generic name for Mould.)

H a b . On the dung of some small animal, Archer.
Remarkable for its oehroleucous aspect. Tbe spores are elliptic, with one side nearly straight, and are about
iuch loDg. SpoTangia tawny, globose.

Flocci fértiles, sporangiis terminati, in massam subglobosam compacti. Sporidia ignota.
The fructification of these curious tniffle-like Moulds is not satisfactorily kuown. The vesicles are just like
e of Ifiico?-, but liave not been observed to contain sporidia. (Name from o-Sov. within, and yiyvo/xai, to be
