572 Ellis and Everhart : New Species of 



Urocystis gei E. & E. 



On leaves of Gaim ciliatum Pursh, Waitesburg, Wash., May 

 7, 1900 (Robert M. Horner, no. 1430). 



Sori epiphyllous, bullate, elongated, .5-1 cm. long, opening 

 along the middle as in U. anemones, formed by the inflated epider- 

 mis ; central spores paler, subglobose, 12-16 fi diam. ; peripher- 

 ical spores darker, slightly granular-roughened, globose, 10 [i 

 diam., or ovate, 10 x 6-7 //. 



Puccinia bicolor E. & E. 



On leaves of Hieracium Sconleri Hook., Waitesburg, Wash., 

 May 7, 1900 (Robert M. Horner, no. 1433). 



Mostly hypophyllous but also amphigenous. Teleutospore 

 sori small (.25— .5 mm.), subcuticular straw-yellow, flat and scale- 

 like at first, gregarious and subconfluent on pallid, subindefinite, 

 orbicular, subconfluent spots 3-5 mm. diam. The central son 

 soon become black and thickened and burst the cuticle which, 

 however, still partly envelops them. Teleutospores clavate- or ob- 

 ovate-oblong, smooth, upper cell subglobose, the epispore strongly 

 thickened above, often subtruncate and almost opake, lower cell 

 mostly narrowed to the stout pedicel which is of about the same 

 length as the spore, which is distinctly constricted. 



Very different from P. Iiieracii. 



Phyllosticta similispora Ell. & Davis. 



On Solid ago rigida, Racine, Wis., Sept., 1898 (Davis, no. 



984). 



Epiphyllous, spots small, scattered, black, convex, 1-2 mm. 

 diam., sometimes confluent, without any definite border resembling 



small black swellings on the leaf; perithecia prominent, black, 

 1 00-150// diam., 1-6 on a spot; sporules almost exactly like 

 those of P. spliaeropsispora E. & E. on Solidago confinis from 

 California, obovate-elliptical, shaped much like apple seeds, some 

 of them globose (perhaps because seen endwise). 



The California species is on large, 1 cm., thin, white spots with 

 a narrow but distinct margin. 



Phyllosticta smilacis E. &. E. 



On leaves of Smilax, Oldtown, Me. (Prof. F. L. Harvey). 

 Common also around Newfield, N. J., and sent from various other 

 sections.
