Orig. Desc. "Sori on both sides of the Jeaves, but mostly epiph vllous, 

 small to medium sized, globose to linear, often confluent on the stems; 

 uredosori cinnamon-brown; spores elliptical, ovate, or globose, 30 to 

 43x24-33/;, yellow-brown to chestnut-brown, very closely covered with 

 small warts, and with 4 equatorial germ-pores; teleutosori black- 

 brown, pulvinate, naked; spores elliptical, rarelv obovate, not at all or 

 only slightly constricted, rounded at both ends, apex with a broad- 

 hooded thickening, 32-41x23-28/-/, smooth, dark chestnut-brown; pedi- 

 cel up to 160 11 long, hyaline." 



The great similarity of the uredo- and teleutospores in form, 

 size and color, and the remarkably long hyaline pedicels of the 

 latter, make this a notable species. The sori often occur in 

 dense masses, especially upon the stem and the branches of 

 the inflorescence. The walls of both kinds of spores are 

 quite thick. Smaller, more globose, paler and thinner walled 

 uredospores occur sparingly among those of the usual form, 

 and might easily be mistaken for an admixture of another 

 species, as they appear to be mature and viable. The apical 

 thickening of the teleutospores is not a prominent feature, and 

 is sometimes absent.
