of numerous loosely connected teleutospores, 5o-100m in 
diameter. Teleutospores roundish, shortly elliptical or poly- 
gonal from mutual pressure, yellowish brown, transparent, 
rough, with minute tubercles and toothed ridges, 12-18 x

ALLIED AND ASSOCIATED SPECIES. 
Doubtful Ustilaginei (Graphiola, Entorrhiza, Tuberculina). 
The descriptions of the British species of Protomyces are also 
given, both because they are apt, on cursory examination to be 
confounded with the Entylomata, and also because they have 
been described with them.* 
GRAPHIOLA. Poiteau. 
Mycelium in the tissues of the living plant, forming small con- 
ceptacles, which burst through the cuticle of the plant. Peridia 
roundish, the outer hard, formed by the intertwining of the my- 
celial hyphz, the inner peridium thin, enclosed by the outer, 
filled with hyphe, sterile and spore-bearing. Spore-forming 
hyphe at the base of the conceptacle, yellow, filamentous, 
crowded, becoming septate above into short joints, of which the 
uppermost gradually mature. Spores formed from cells, which are 
given off laterally from the joints, and which become abjointed 
* Professor Marshall Ward considers that the Schinzda leguminosarum of 
Frank, which causes the tubercular swellings on the roots of the Leguminose, 
is allied to the Ustilaginez, but the evidence (Phd/. Trans., 1887, pp. 539-562) 
adduced by him seems hardly to be conclusive.
