less concentrically arranged ; spores subcylindrical, often a 

 little curved, supported by slender sporophores, oozing out and 

 forming a reddish mass, .001 to .0016 in. long, about .00012 in. 

 broad. 



Living leaves of poplar, Populus grandidentata. Freeville. 

 July. 



This species may be distinguished from other species of 

 Gloeosporium growing on poplar, by its narrow elongated spores 

 which are not much unlike those of some species of Septoria. From 

 Cylindrosporium it is separated by the agglutinated spore mass. 

 From G. stenosporum, which occurs in Kansas on leaves of 

 Popidus monilifera^ ii^ differs in its smaller darker-colored spots, 

 and in its darker colored spore-masses, which are hypophyllous, 

 and in its longer and simple spores. 



Gloeosporium allantoideum n. sp. 



Heaps minute, numerous ; spores cylindrical, curved, obtuse, 

 .0005 to .0008 in. long, oozing out and forming minute whitish 

 masses which are concentrically arranged. 



Kind of pumkin. Lyndonville. January. C. E. Fairman. 



The heaps are sometimes overrun by mucedinous filaments. 



The species is distinguished from G. lagenarium by its curved 



spores. 



Puccinia Zopfii Wint. 



Living leaves of cowslips, Caltha palustris. Buffalo. G. W. 

 Clinton. 



In reviewing some specimens of Puccinia on leaves of Caltha 

 palustris sent me several years ago by the late Judge Clinton, I 

 find some belonging to this species. He also sent me the true 

 Puccinia Calthce, so that these species meet on common ground 

 in the western part of the State. 



Ustilago Tritici Jensen. 



Heads of wheat, Triticum vulgare. Meadowdale, Albany 

 county. June. 



This and the next following species have by most writers 'been 

 included with the smut on oats as mere forms or varieties of the 

 one comprehensive species Ustilago segetuni. But Jensen indi- 

 cated their distinct character, and the investigations of Professors 

 Kellerman and Swingle have confirmed his views.
