Ph. rubi, (Pers.) Winter. 
IL., 101. Hypophyllous. Sori, very small, scattered; ure- 
dosori often very numerous, circular, orange-yellow, without 
paraphyses; uredospores ovate or elliptical, each borne upon a 
pedicel, epispore thin, finely echinulate, 12-15 by 15-20 u; te- 
leutosori rounded, sometimes confluent, black; teleutospores 
about four to five septate, cylindrical, somewhat constricted at 
the septum, ends obtusely rounded, the vertex furnished with a 
conical, more or less deeply tinted apiculus, surface finely tu- 
berculate, sometimes appearing smooth, dark-brown, 36 by 100 
#; pedicel as long as the spore or somewhat longer, very much 
swollen in the lower half.

TRIPHRAGMIUM, Linx. 
Teleutospores dark brown, three-celled, triangular, the di- 
viding septa vertical and horizontal or oblique; uredospores 
similar to those of Puccinia. 
In this genus ecidioforms have not been certainly recog- 
nized, though there are in some cases what have been called 
two forms of the uredo, the one occurring in the spring on the 
petioles and veins, the other late in the summer on the leaf 
surfaces, and spermogonia are developed upon the upper leaf- 
surface. 
The species are comparatively few; none have so far been 
found in Tlinois. 
RAVENELIA, BERKELEY. 
Teleutospores many-celled, berry-like, with vertical and 
horizontal septa, usually with a series of hyaline cells at the 
base, pedicellate or sessile. 
This curious genus is comparatively little known, and its 
standing among the Uredinew has not been firmly established.
