104 UROMYCES 
Teleutospores. Sori similar, but less pulverulent, and 
blackish-brown; spores subglobose to ovate, 
not thickened above, but with a hyaline 
papilla as much as 6 uw high, smooth, brown, 
2235 x 1825 w; pedicels short, hyaline, 
deciduous.

Teleutospores on G. pratense, G. pyrenaicum, G. silvaticum. 
Cane Not common. Atcidia, March to June; 
teleutospores, June—October. (Fig. 57.) 
Liro proved that the ecidium of this parasite from G@. silvaticum 
produced uredo- and teleutospores on the same plant, and Bock showed 
that the uredospores from the same species reproduced themselves on 
other hosts of the same genus. But there is another ecidium occurring 
on G@. pratense and G. silvaticum, which belongs to a quite different life- 
cycle. This is cidium sanguinolentum Lindr., and is the ecidial stage 
of the hetercecious Puccinia Polygont-amphibii Pers. (q.v.). It differs 
from the ecidium of U. Geranit in being seated on conspicuous blood-red 
or deep-purplish spots which are not distinctly thickened ; moreover the 
shape of the spores is that usual in ecidiospores, viz. rounded-polygonal, 
while those of U. Geranii are always more or less ovate, and have a 
thicker wall. 
Again, there is an ecidium on G. pusillum which, according to Sydow, 
is probably also found on G. molle and @. rotundifol/um, and which belongs 
to Puceinia Polygoni-Oonvolvuli (q.v.)—a form of P. Polygoni-amphibii 
which is often separated as a distinct species. The uredo- and teleuto- 
sori would, of course, not follow the wzcidium on the same plant in either 
of these two cases. 
On G. pyrenaicum there is another Uromyces (U. Kabatianus) which 
differs in the arrangement of its sori ; see below.
