The following species have never before been cultivated in Amer- 
ica or elsewhere, so far as the writer knows. 
1. PucciNiA TUMiDiPES Peek. — Excellent telial material of this 
species on Lycium pallidum, was sent by Mr. W. A. Archer, col- 
lected in the Organ Mountains, N. Mex., on Oct. 9, 1914. As it 
was found the teliospores would germinate, it was sown Dec. i, 
1914, on plants of Lycium vulgare, giving a few pycnia only 
by Dec. 18, with no further development, possibly owing to the 
poor condition of the host plant. It was sown again on another 
plant of the same sort Dec. 12, 1914, giving rise to a few groups 
of pycnia by Dec. 21, and a single uredineal sorus Jan. 16, 1915- 
Although the growth of the fungus was not vigorous, and did 
not continue to the final stage, yet it seems safe to conclude that 
the rust is autoecious, and without cupulate aecia. It clearly 
belongs in the genus Bullaria, where it becomes B. tumidipes 
(Peck) comb. nov. 
2. PucciNiA Distichlidis Ellis & Ev. — This rust in the first 
place was sent to Mr. Ellis in 1891 by F. D. Kelsey of Helena, 
Mont., and labeled as on " Distichlis maritima,” but afterward was 
shown by the writer^® to be on Spartina gracilis. On account of 
this erroneous determination of the host plant, the rust was re- 
named P. Kelseyi by Sydow.®® In a study of “ Correlation be- 
tween certain species of Puccinia and Uromyces ” Orton^^ came 
to the conclusion from a comparison of the morphological charac- 
ters and geographical distribution of Uromyces Spartinae and the 
rust in hand, that it was “ extremely probable that its aecial host 
is some member of the primrose family, perhaps Steironema,’* 
this being one of the aecial hosts for the Uromyces. It has been
