92 Uromyces Leguminosae. 



III. Teleutosori on stems towards their base, elongated oval, dark- 

 brown, appearing almost black, confluent, erumpent. 



Teleutospores at first intermixed with uredospores, yellowish- 

 brown to chestnut-brown, smooth, oval to ovate, or elliptical to 

 broadly clavate, apex much thickened (11 p) and rounded, some- 

 times tapering or flattened, 27-37 x 15-19ju, average 30 x IS p ; 

 pedicels long, persistent, hyaline, up to 45 ^ long. 



On stems and leaves of Asperula oligantha F.v.M. 



Victoria Ardmona, May to Oct., and in moist places all the 

 year round (Robinson). 



The host-plant is given as Asperula scoparia Hook, f., in the Index 

 Kewcnsis, but the synonymy seems a little confused. A. oligantha F.v.M. 

 is first given as Rubia syrticola Miq., then R. syrticola is given as a 

 synonym of Asperula scoparia Hook. f.

Uromyces phaseoli (Pers.) Wint. 

 [O. Spermogonia on minute spots, whitish.] 



[I. Aecidia densely crowded in small annular groups ; pseudoperidia 

 sliortly cylindrical, whitish, with deeply cut reflexed margins, 

 Aecidiospores polygonal, finely warted, colourless, 17-32 x 

 14-23 p.] 



II. Uredosori on both surfaces of leaf, round, pale cinnamon brown, 



pulverulent, solitary or crowded and confluent, soon naked and 

 surrounded by ruptured epidermis. 



Uredospores yellowish brown, ellipsoid to ovate, finely echin- 

 ulate, 23-32 x 17-22 p. 



III. Teleutosori dark-brown, almost black, easily detached, otherwise 

 like uredosori. 



Teleutospores dark brown to chestnut brown, subglobose to ellip- 

 soid or oblong, smooth, scarcely thickened at apex, with broad pale 

 flattened papilla, 27-37 x 19-25 p. ; pedicel hyaline, persistent,, 

 elongated, up to 70 p long.

The distinction between the teleutospores of U. fabae and U. appendicu- 

 latus is very marked. In the one the apex is thickened up to 9 p, while in 

 the other the thickening is not perceptible.
