Silphium integrifolium: Union, Sept. 22, II., IIL, (Earle.) 
S. terebinthinaceum: Jersey, Oct. 18, 6298. Helianthus: Piatt,

Nos. 1912, 2006, 2060, 2205, 2481, 5817, 5881, 5950 and 
6187 are accompanied by pycnidia of Dothidea solidaginis. 
The name adopted is from Uvedo sonchi-arvensis, Persoon. 
For the fungi here included many names have been proposed 
under the idea of specific distinctness. But whatever differ- 
ences exist seem to be so connected by intermediate forms that 
those upon the host-plants named are considered specifically 
identical. There are, therefore, included such as have been 
named Uredo Solidaginis, Schw.. U. terebinthini, Schw., Coleo- 
sporium compositarum, Lév., Uredo or Ceoma elephantopodis, 
Schw., Coleosporinum Vernonia, B.&C., and C. Solidaginis, Thiim. 
Perhaps the form on Vernonia differs more than others from 
the type on account of the uredospores being smaller, and the 
‘teleutospores being more enlarged above. On Elephantopus 
the teleutosori are grouped in circles. 
C. ipomceee, (Schw.) 
Il, IJ. Hypophyllous. Spots yellowish or none; sori 
minute, scattered or irregularly clustered, circular. II. Spores 
irregularly oval, strongly echinulate, 18 by 26 ». III. Sori 
convex, deep reddish orange; spores (chains) oblong or slightly 
clavate, conspicuously 4-6-septate, about 10 by 26 », segments 
widest transversely.
