The following sotes include a number of corrections of errors 
and some additional information with regard to species mentioned 
‘n some recent papers. In Proc. Amer. Acad. xviii. 76, it was 
stated that Uredo Towicodendri, Berk. and Rav., is the teleuto- 
Sporic form with which Pileolaria brevipes, Berk. and Rav., is to 
be associated as the uredo form. I was lead to this conclusion 
because, in the large number of cases which I had examined, the 
. Toxicodendri appeared to be the prevailing form late in the sea- 
son. Although the number of cases examined by me seemed 
ineans of deciding with certainty which is the uredo and which 
the teleutosporic form is the mode of germination which, at the 
time of writing, I had never been able to observe. During the 
past summer I obtained the germination of the spores of the so- 
called Uredo Toxicodendri, and found that their mode of germi- 
hating is that of a uredo and not of a teleutospore. The germinal 
pee are large, and, in spite of the prominent apical papilla, the 
‘ubes in the cases I saw were more frequently lateral than apical. 
he spores of the so-called Pileolaria brevipes I have not yet been 
able to make germinate, after repeated attempts.
