Uromyces Gramineae, Liliaceae. 87 



Sporobolus. 



3. Uromyces tenuicutis McAlp. 



II. Uredosori on both surfaces of leaves, but mostly on upper, and on 



stems, elliptic to oblong, orange-yellow, pulvinate, generally 

 minute, but may reach a length of 1 mm., at first covered by 

 epidermis, then erumpent, pulverulent. 



Uredospores orange, ellipsoid to ovoid, spinulose, rather large, 

 with two distinct germ-pores on one face, equatorial or nearly so, 

 28-40 x 19-24 p, average 32 x 22 p. 



III. Teleutosori on lower surface of leaf, minute, pulvinate, covered by 

 epidermis. 



Teleutospores yellowish-brown, smooth, obovate to oblong or piri- 

 form, irregularly rounded or truncate, or even pointed at apex, 

 and slightly thickened, sometimes broader than long, 22-35 x 

 16-25 ju, average 28 x 20 p ; pedicel sometimes persistent, usually 

 tinted, commonly 20-35 p long, but often much shorter. 

 On leaves and stems of Sporobolus indicus R. Br. 

 Victoria Near Melbourne, Aug. March. 



U. sporoboli E. and E., found on leaves of Sporobolus asper Kunth, in the 

 United States, has no uredo-stage, and the teleutosori are soon naked, while 

 the teleutospores may be subglobose and provided with long pedicels. 



Darlucafilum Cast., is very commonly associated with the uredospores.
