298 British Uredinee and Ustilaginee. 
by transverse septa. Spores spherical or elliptical. Between. 
the spore-forming hyphe arise bundles of sterile hyphz, which 
grow up out of the peridium and carry up with them the spores. 
The spores germinate by the development of a filamentous 
mycelium, or by the formation of fusiform sporidia. From the 
investigations of E. Fischer,* it would appear that. this fungus is 
related to the Ustilaginei both. by its.spore-formation and by the 
manner in which its spores germinate. 
Graphiola pheenicis: (Moug.) 
Conceptacles erumpent on the leaves of the host-plant, 1-1°5 mm. 
wide, ‘5mm. high, opening above and allowing the sterile 
hyphe to protrude. Outer peridium black and corneous ; 
inner peridium delicate, colourless. Sterile hyphe yellow, 
protruding 2 mm..or more. Spores ex masse yellow, globose 
or elliptical, 3-6 across. Membrane thick, colourless, smooth..

Mycelium parasitic in the tissues of living plants, producing 
large spores at the ends of lateral branches. Spores simple, 
single or numerous in the cells of the host-plant. Epispore 
thick, germinating by one or more thin germ-tubes, which are 
sometimes slightly branched, and which develop, both at their ° 
ends and lower down, small sickle-shaped promycelial spores +
