NOTES ON SOME UREDINE*E OF THE UNITED STATES. 
By P. Dietel. 
In a recent number of this journal Mr. Anderson has stated that 
Uromyces sophorw, Pk., and Uromyces hyalinus, Pk., are identical, but 
erroneously says that they are referable to Uromyces trifolii , (Hedw.) 
Lev. In the latter fungus the same morphological characters are con¬ 
stant in both the American and European specimens, viz, dark brown 
teleutospores with a minute hyaline papilla ; the latter often wanting. 
On Sophora sericea the spores are lighter in color and the papilla is very 
broad. There is still greater difference between the tw^o species as re¬ 
gards their biological properties. Teleutospores only have been found 
on Sophora , and the fungus seems to hibernate by its mycelium. The 
affected plants, therefore, can be distinguished from the healthy ones 
by their slenderer growth. In the majority of specimens I have seen 
the sori appear on all the leaves of the plant, the youngest as well as 
the fully developed ones. Uromyces hyalius differs also from Uromyces 
glycyrrhizcc , (Rabh.) Magn., lately described by Prof. Dr. Magnus in the 
“ Berichte der Deutschen Botauischen Gesellschaft.” This fungus oc¬ 
curs in America on Glycyrrhiza lepidota and greatly resembles Uromy¬ 
ces trifolii , in its morphological characters, differing from it, however, 
by the perennial mycelium of the primary uredo stage and the absence • 
of the secidial fructifications. 
In Hedwigia, 1889, p. 23, I have stated that Uromyces caricis , Pk., 
on Car ex stricta is the Uredo of a Puccinia, which I have named Puc - 
cinia caricis-strictw. As Prof. B. D. Halsted notes in the Journal of 
Mycology, vol. 5, p. 11, he*has also seen the Puccinia, but considers 
it as a two-celled form of a normal Uromyces. But there can be 110 
doubt that the so-called Uromyces is really the Uredo of the Puccinia, 
because it has four equatorial germ pores. Uromyces per igynius, Hals., 
is, however, a true Uromyces but the spores do not measure, as the 
author states, 1-G by 8-10/* but 13-20 by 26-36/*. 
Puccinia vernonice, Scliw., is considered by most mycologists as a 
variety of Puccinia tanaceti , DC. or P. helianthi , Schw.; or as identical 
with P. Meracii , (Schum.) Mart. [ P.flosculosorum , (Alb. & Schw.) Roehl]. 
A comparative examination of these species has shown that it is suffi¬ 
ciently different from any of them to constitute it a good autonymous 
species. It differs from Puccinia Meracii principally in having a much 
thicker epispore and frequently a thickening at the apex. In P. heli- 
antM and P. tanaceti the teleutospores have a firm stalk and are clearly 
constricted at the septum, in P. helianthi more than in P. tanaceti. In 
the latter the spores, when examined dry, are beset with minute tuber- 
cules, in P. helianthi they are entirely smooth. The membrane of P. 
helianthi is thicker than that of P. tanaceti. P. vernonicc has somewhat 
smaller spores than the two former species. They are usually not at 
all or only very little constricted at the septum, the membrane is beset
