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 Alisma Plantago, Rooks and Saline Co.; Sagiitaria 

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

 Sagittariae .* 



V. SOKOSPORIUM. 



31. S. atrum Peck, Bot. Gaz., 1880, p. 35. (!) 



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 XXV1I.4, 5.) 



In enlarged stems and contracted inflorescence of Solidago 

 Missouriends, 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 in 

 dry cultures long chains of air conidia are produced. 



VI. UROCYSTIS.f 



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

 p. 375. 



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

 omew). 



No material for germination. 



* A Doassansia 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 

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

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

 the two.
