Spots bright yellow, galls hemispherical, sori spherical, .18-.20 
mm. in diameter, zoosporangia about .015mm. in diameter, 
generally very numerous. Resting spores unknown.

Massachusetts to Minnesota and southward to Maryland. 
The most common and striking species in the Northern States, but the 
southern limit is not sufficiently known. In Bull. Bussey Inst. 1. c. I gave a 
detailed account of the development of the sori and their germination, but 
common as the species is I have never found resting spores. e species 
abounds near Cambridge from the middle of May until the middle of October. 
The young plants, as soon as they can be recognized in the spring, are often 
covered with the bright yellow sori, which are frequently mistaken for a uredo. 
_ After the sporangia have been discharged the spots resemble ecidia. I can 
find no difference later in the season, and when vegetation is killed by the frost 
in October the sori are as abundant as ever, but no trace of resting spores h 
been found, Surely, if our plant bears resting spores which resemble those of 
8. fulgens, there ought to be no difficulty in detecting them. As it is, it seems to 
me best to consider our form as distinct from S. fulgens, of which I formerly 
considered it a variety, relying on the resemblance of the sori which, in 97 
cases, are bright yellow, and project rather prominently at first, but afterwards 
assume an wecidium-like form. :
