What has been called Uredo niiniafa, Pers., Ca>oui.<i miniata, 

 Schl.. or Coleospor'nim, miniatHm^ Lev., has been considered the 

 fficidioform of PJnvf/Jiiidiinii )nitcroHafni)i, Pers.. with which it 

 is certainly often associated. But it is very commonly found 

 on the green leaves, in the early part of the season, with Ph. 

 SjH'ciof^tnii on the twigs at the same time. Sometimes, however, 

 the teleutospores of Pli. nmrronatiiDt occur later in the season 

 on the Caeoma-affected leaves or on other leaves of the same 

 ])hint. 



All the numbers except 5952 and ()273 were accompanied 

 by the aliove -mentioned form. 



Ph. rubi-idaei, (Pers.) Winter. 



II., in. Hy})ophyllous. Uredosori small, scattered, usu- 

 ally very numerous; uredospores obovate or elliptical. e])is})ore 

 thin, sharply echinulate. 15-18 ^; teleutosori small, scattered. 

 l)Owdery, black: teleutospores cylindrical, ends obtusely round- 

 ed, vertex furnished with a more or less elongated, conical, or 

 often somewhat cylindrical hyaline apiculus, whole surface 

 very rough-warty, almost black, about six- to eight-septate, 

 27-38 by 67-120 ^\ pedicel tinted near the spore, otherwise hy- 

 aline, about one and a half times the length of the spore, from 

 above the middle downward elongate-elliptical, roughened. 



On leaves of Piibiis sfrhjosKs: McHenry, Aug. 20,1177, 

 Aug. 23, 1232; Boone, Sept. 2, 1422, II.; Cook, Sept. 5. 144(), 

 II.; Stephenson, Sept. 14, 5882, II., III.; JoDaviess, Sept. 20, 

 6012, II. 



The teleutosori are surrounded by many incurved colorless 

 (dry specimens) clavate paraphyses, ]>ut a careful examination 

 of the specimens failed to reveal them with the uredosori. 

 though these were over-mature, and the spores everywhere 

 scattered among the matted hairs of the leaf.
