What has been called Uredo ininiata, Pers v Cwoma miniata, 

 Schl., or Coleosporium miniatum, Lev., has been considered the 

 HBcidioform of Phraymidium mucronatum, 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. 

 speciosum on the twigs at the same time. Sometimes, however, 

 the teleutospores of PJt. vmcronatinn occur later in the season 

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

 plant. 



All the numbers except 5952 and 6273 were accompanied 

 by the above mentioned form. 



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



Il. ; III. Hypophyllous. Uredosori small, scattered, usu- 

 ally very numerous; uredospores obovate or elliptical, epispore 

 thin, sharply echinulate, 15-18 /*; teleutosori small, scattered, 

 powdery, 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, 

 27-33 by 67-120 /u; 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 Eubiis strigosus: 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, but 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.
