Family 1. MUCORACEJE. DBy. 
Hyph® producing sporangia, reproduction non-sexual by spores 
or chlamydospores, sexual by zygospores. Aerial fungi, growing 
on putrescent substances. 
Genus 1. FILOBOLUS. Tode. 
Hyph® erect, simple, continuous, dripping, gradually bullate 
from the attenuated base, ejecting the sporangium from the apex. 
Sporangia globose-depressed, black. Spores unilocular, globose, 
hyaline, then pallid.

Syll. 502. 
Threads slender, pellucid, weeping, yellowish, clavate at the apex 
(5-7 m.m. high). Sporangia hemispherical (300 p broad), black, 
verrucosc, cuticle reticulate, columella conoid, dark blue ; spores 
uniform, elliptic, epispore thin (7-10 x5-6 p), pale yellowish. 
On dung. Queensland. 
Genus 2. MUCOE. Mich. 
Sporange-bearing hyph® erect or branched, often septate ; 
mycelium creeping, hyaline, septate ; sporangia globose or pul- 
vinate; columella cup-shaped. Spores one-celled, globose, hyaline, 
or coloured.

echinulate, yellow or greenish grey, when dry dark brown, minute ; 
spores ellipsoid or ovoid-ellipsoid, simple, even, becoming yellowish, 
6-9 x 3-4 p. Zygospores sph®roid, epispore studded with irregular 
prominences, black, 99-214 p. diam. Columella ovoid, yellow-
