DESCRIPTIONS OF THE BRITISH 
UREDINE#. 
UREDINEA. Tulasne. 
MYcELIuM parasitic in living plants. Spores formed from the 
ends of erect, crowded hyphe, usually of more than one-kind. 
Teleutospores germinating by a short promycelium. 
VROMYCES. Link. 
Teleutospores separate, unicellular, pedicellate, produced in 
flat sori (spore-beds), apex perforated by a single germ-pore. 
I, EUUROMYCES. Schroter. 
Having spermogonia, zcidiospores, uredospores, and teleutospores, the 
latter germinating only after a period of rest. 
A. AUTEUUROMYCES. 
Having all spore-forms on the same host-plant. 
Uromyces fabe. (Pers.) 
Acidiospores—Pseudoperidia generally crowded upon whitish 
spots, which are more or less circular, short, slightly pro- 
minent, flat, with torn white edges. Spores subglobose, 
orange-yellow, finely echinulate, 15-25 in diameter. 
Uredospores—Sori chestnut-brown, roundish, amphigenous, scat- 
tered, often confluent, soon naked. Spores subglobose or 
ovate, with three germ-pores, shortly echinulate, yellowish 
brown, 20-30 X 17-204. 
Teleutospores—Sori rounded .on the leaves, more abundant and 
elongate on the stems, persistent, black. Spores variable 
in form, ovate or broadly clavate, dark brown, smooth, apex 
much thickened (8-10), rounded or conical with one in-
