REPORT OF THE BOTANIST. 103 



Helicosporium elliptic um n. sp. 



Tufts elliptical or oblong, sometimes confluent or effused, 

 greenish-brown or brown ; flocci intricately and somewhat 

 reticulately branched, colored, septate, the articulations 

 three to five times as long as broad ; spores very long, 

 closely coiled in about eight volutions, forming ellipsoid 

 masses, greenish-yellow, containing many nuclei. 



With the last, than which it is muoh darker colored. The 

 flocci appear to anastomose as in the capillitium of Stemon- 

 itis. The spores are not distinctly septate. (Plate 2, figs. 

 9-12.) 



Sporidesmium coisrciisnsruM B. & C. 



Decaying wood. Buffalo. September. Clinton. 



Puccinia Veratri Clinton Niessl. 



Spots indefinite, yellowish ; sori scattered, small, brown ; 

 spores elliptical, often irregular, constricted in the middle, 

 easily separating at the septum, pale, .001' long, .00065' 

 broad ; peduncle very short. 



Lower surface of leaves of Veratrum viride. Buffalo. 

 July. Clinton. (Plate 2, figs. 13 and 14.) 



Under slight pressure the spore readily separates into two 

 parts as in P. Lobelias. 



Uromyces Lilii Clinton n. sp. 



Sori amphigenous, small, scattered, surrounded or partly 

 covered by the ruptured epidermis, brown ; spores obovate, 

 rough, .0011-.0015' long, .0008'-. 001' broad ; often with a 

 slight apiculus at the apex ; peduncle very short. 



Leaves of Lilium Canadense. Buffalo. July. Clinton. 



The roughness of the spore appears to be produced by 

 little pits or depressions. The species is related to U. apicu- 

 losa and U. Euphorbia. 



Uromyces Phaseoli Strauss. 



Leaves of Phaseolus. Yonkers. Dr. E. C. Howe. 

 I have seen no description of this species and have deter- 

 mined the specimens by comparison with those received from 

 Dr. Curtis under the above name.

 Jervis. September.
