This specimen was collected by Dr. C. E. Bessey on Sep- 

 tember 29, 1874 and is certainly well worthy of note. The 

 ovaries are swollen and congested and protrude from the 

 glumes, otherwise the flower is uninjured; the glumes 

 remain intact and apparently develop normally. In 

 microscopic appearance it resembles Ustilago piisttilata 

 Under a magnification of about 20 diameters the spore balls 

 appear as rounded granules. 



Doassansia Cornu. Ann. Sci. Nat. Bot. VI: 15: 285. 1883. 



Affecting acquatic plants. Spore masses consisting of a 



large number of fertile spores surrounded and enclosed by 



a covering of sterile spores, imbedded in the plant tissues. 



Doas.sania, Sp. 



Specimen on Sagittaria variabilis, Ex. Herb. J.C.Arthur 



(1843) Decorah, E. W. D. Holway. 



This specimen was very small and since Dr. J. J. Davis 



had said it was too imature for identification, no attempt 



was made to name it. The sori, however, appeared 



to be quite different from those of Doassansia sagiftariae 



West) Fisch.
