282 | FLORA OF TASMANIA. [4lge, by W. H. Harvey. 
Gen. LXXXVI. MUCOR, Mich. 
Flocci tubulosi, fertiles erecti, terminati sporangio membranaceo dehiscente (raro diffluente) includente 
sporidia discreta. 
The species of this genus are developed upon all sorts of decaying substances. The vesicular heads, which do 
not collapse, as in Ascophora, distinguish the genus. Little is known of exotic forms. (Name from the Latin 
mucor ; a generic name for Mould.) 
l. Mucor cervinoleucus (Berk.); flocci simplices, deorsum candidi, sursum ochracei, sporis sub- 
cymbeformibus, | 
Has. On the dung of some small animal, Archer. 
Remarkable for its ochroleucous aspect. The spores are elliptic, with one side nearly straight, and are about 
sess inch long. Sporangia tawny, globose. 
Gen. LXXXVII. ENDOGONE, 24. 
Floeei fertiles, sporangiis terminati, in massam subglobosam compacti. Sporidia ignota. 
The fructification of these curious truffle-like Moulds is not satisfactorily known. The vesicles are just like 
those of Mucor, but have not been observed to contain sporidia, (Name from evdov, within, and 'ywyvopau, to be 
produced.) 
1. Endogone australis (Berk.): hemispherica, alba, sporangiis magnis centralibus aggregatis. 
Has. On the ground, Archer, 
Hemispherical, about 2 lines across, white. Sporangia confined to the centre, 41, of an inch or more across, 
greenish, collected in little groups. —The pale colour, more branched threads, and central sporangia, distinguish this 
interesting species, of which there is only a single specimen in the collection.—PrAT& CLXXXIII. Fig. 15, a, plant, 
nat. size; b, section of ditto; c, external threads ; d, sporangia :—maguified.
