view and to assign to U. Ornithogali collections on Quamasia 

 made in Indiana and Oregon as follows : 



Quamasia hyacinthina (Raf .) Britton. Lafayette, Tippecanoe 

 Co., Indiana, May 30, 1907, F. Vasku ; May 22, 1916, H. S. Jack- 

 son; May, 1917, G. N. Hoffer. 



Quamasia quamash (P.ursh) Coville. N, W. of Corvallis, 

 Benton Co., Oregon, April 7, 1914, H. S. Jackson, 1969; May 1, 

 1915, H. S. Jackson, 3409. 



According *to this treatment, the smut on Liliaceous hosts be- 

 longing to the tribe Scilleae, including besides the American 

 Quamasia, species of Muscaria, Ornithogalum and Scilla in Eu- 

 rope, would be assigned to U. Ornithogali, while U. Colchici 

 would include the European form on Colchicum autumnale. 

 The writer is not able to express an opinion as to whether the 

 form on Convallariaceae in Europe and America is properly 

 assigned to either of the above species, as sufficient material has 

 not been avai4able for study. Clinton 5 has assigned specimens 

 on Salamonia and Vagnera, collected in Iowa and Montana, 

 somewhat doubtfully to U. Colchici. 



U. Ornithogali differs from U. Colchici chiefly in the widely 

 different character of the sorus, the size of the spores, and the 

 character and wall color of the surrounding layer of sterile cells. 

 In the formef the sori are elliptical, commonly half as broad as 

 long, the spore balls consist usually of one, rarely two spores, 

 which are 18-22//, in diameter, and the sterile cells form a firmly 

 united unbroken spore covering, the walls of which are cinnamon- 

 brown. In the latter the sori are linear, often ten or more .times 

 as long as broad ; the spore balls consist of one to two, rarely 

 three spores, which are 14-20//. in diameter; the sterile cells with 

 light cinnamon-brown walls form a loose often interrupted layer 

 over the spores.

In North America this species has apparently been reported 

 only from Alaska on Trientalis arctica. Three collections have
