112 Forty-sixth Report on the State Museum, 



Cylindrosporium Acori n. sp. 



Spots numerous, subelliptical, sometimes confluent, blackish, 

 nuclei minute ; spores amphigenous, forming minute tufts, white, 

 oblong or subcylindrioal, sometimes narrowed toward one end, 

 .0004 to .0008 in. long, about .00016 broad. 



Living or languishing leaves of sweet flag, Acorus Calamus. 

 Sandlake. September. 



The spots, in size and shape, resemble those of Uromyces 

 pyriformis. They are sometimes slightl}^ whitened in the center 

 by the confluence of the tufts of spores. 



TJrocystis Waldsteiniae n. sp. 



Sori large, oblong, following the nerves of the leaf, commonly 

 near the margin and nearly parallel to each other, surrounded 

 by the ruptured epidermis, black; spores not easily separable, 

 three to six or more in a glomerule, the central and peripheral 

 similar, subglobose or elliptical, often angular, .0005 to .0006 inch 

 long, .0004 to .0005 broad, the glomerules very unequal in size 

 and in the number of component spores. 



Living leaves of barren strawberry, Waldsteinia fragarioides. 

 Alcove. June. C. L. Shear. 



This species is apparently closelj^ allied to U. Filijjeiuholcn. It 

 seems to connect Urocystis with Thecaphora and to be ambiguous 

 between these two genera. When there are but three spores in a 

 glomerule the central one is usually larger than the others. 



Specimens of this fungus have also been received from Pro- 

 fessor Dearness, of London, Canada. 



Cryptospora Goeppertiana Kuhn. 



Living stems and branches of Canadian blueberrv, YaGcinium 

 Ca/nadense. Fulton Chain. August. Also on the same host 

 and on swamp blueberry, Yacciniiiin coryrnbosiim. Sandlake. 

 September. 



This fuuor-us is destructive to its host. The affected branches 

 appear to live but one year. Their leaves are dwarfed in size or 

 wholly obliterated, the branches themselves are generally unnatu- 

 rally multiplied, and appear to form tufts or clusters, and they 

 are unusually thick or swollen and their tissues greatly changed. 

 Sometimes they are much twisted, curved or contorted, but more
