IV. DOASSANSIA. 



I have not accurately identified the herbarium material of 

 this genus, and having no fresh material have not attempted 

 germination. 



30. D. Alismatis (Nees) Cornu, Ann. Sci. Nat., Ser. 6, 

 XV. (1883), p. 285. 



On AUsma Plantago, Rooks and Saline Co. ; Sagiitaria 

 variabilis^ Riley Co. The one on the last host may be D. 

 Sagittariae.* 



V. SOBOSPORIUM. 



31. S. ATRUM Peck, Bot. Gaz., 1880, p. 35. (I) 



On Carex Pennsylvanica. Found at Manhattan by Mr. J. 

 E. Payne in 1894. 



Germination unsuccessful. 



32. S. CUNEATUM Schofield, Sec. Ed. Webber's Appendix, 

 Cat. Flora Neb. ( !) (Plate XXV1L4, 5.) 



In enlarged stems and contracted inflorescence of Solidago 

 MissouriensiSf Rooks Co. ; also in an old Solidago, Man- 

 hattan. 



Germination begins in 12 hours. More or less branched 

 tubes pointed at the ends and septate, a few conidia and iu 

 dry cultures long chains of air conidia are produced. 



VI. UROCYSTIS.t 



33. U. Anemonis (Pers.) Schroet., Beitr. Biol. Pfl., 1877, 

 p. 375. 



On leaves of Anemone Oaroliniana, Rooks Co. (Barthol- 

 omew). 



No material for germination. 



• A Doasaansia on Potamogeton is reported from Lawrence by Mr. M. 

 A. Barber of the State University and is probably D. occulta. 



The specimens on onion bulbs distributed by Mr. Bartholomew from 

 Books Co., as U. magica. Pass., are an Aspergillus. I have compared it 

 with de Thumen's specimens of U. magica and find no resemblance between 

 the two.
