 1894 (Commons, No. 2,408). 



Spots of irregular shape, whitish, with a shaded purple border, 1 

 cm. diam. Perithecia crowded in the spots, erumpeut, depressed- 

 globose, 75-90//., with a distinct papilliform ostiolum, of a coarse 

 cellular, dark olivaceous texture. Sporules elliptical, hyaline, 6-9 x 

 5;', filled with small nuclei. Accompanied by Fusicladium Aplectri 

 E. & E. on the same spots. 



Phyllosticta rhoicola E. & E. 



On leaves of Rhns Toxicode)idron,^utta\\huYg, West Va. , Aug. 

 1894 (L. W. Nuttall, No. 567, partly). 



Spots 4-6 mm. diam., deciduous, grayish-white, with a narrow 

 black border. Perithecia epiphyllous, scattered, 100-110," diam., 

 convex-prominent above, visible also below. Sporules narrow-ellip- 

 tical, hyaline, 2-nucleate, 5-6 x 2-3;/. 



Differs from P. toxirui. E. & M. in its larger deciduous spots with 

 a narrow border, and its narrow-elliptical sporules. 



Phyllosticta Anemonis E. & E. 



On leaves of Anemone Pennsylvanica, Ann Arbor, Mich., Oct.

 ing areas of the leaf, more or less distinctly bounded by the veinlets. 

 Sporules short-cylindrical, slightly curved, obtuse, 5-7 x li//. 



This is different from Phyllachora Anemonis (Fr.), which is found 

 both on the petioles and leaves, and has the characteristic stromata 

 of the Dothideaceie, the single stromata being about twice as large 

 as the perithecia of our Phyllosticta. and each containing (sec. spec, 

 in F. G. 192) 3-6 ascigerous cells.
