Uredospores. Sori amphigenous, scattered, roundish, ob- 
long or linear, occasionally con- 
fluent, minute, yellow-brown ; 
spores globose to ovate, faintly 
echinulate, yellow, 20—28 w 
diam. (with 4—6 scattered 
germ-pores on one face, McAl- 
pine). 
Teleutospores. Sori amphi- 
genous, scattered, occasionally 
confluent, minute, generally 
oblong or linear, about 1—1} Fig. snr tla 
mm. long, always covered by : 
the epidermis, black; spores variable, generally oblong to 
clavate, rounded, truncate or obliquely attenuated at the apex, 
slightly thickened (3 ) and darker, gently constricted, narrowed 
below, smooth, brown, 36—57 x 18—24 yu, with a very short 
pedicel. 
fEcidia on leaves and ‘petioles of Ranunculus acris; uredo- 
and teleutospores on Alopecurus pratensis. Very uncommon, 
(Fig. 206.) 
The connection of the ecidium with the Puccinia was first demon- 
strated by Plowright, and has since been confirmed by Dietel and by 
Klebahn. All the teleutospores I have seen were full of a very coarsely 
granular protoplasm. It must not be forgotten that an ecidium on 
Ranunculus acris belongs also to Uromyces Dactylidis,
