 namon-brown, 1.5— 2ju thick, rather finely verrucose. 



Telia chiefly epiphyllous, occasionally on the small stems at the 

 bases of the leaves, hemispheric, 0.5-1 mm. high, oval or oblong, 

 0.7-1 mm. broad by 1-2 mm. long, light chocolate-brown, ruptured 

 epidermis conspicuous; teliospores 2-celled, broadly ellipsoid in 

 general outline, 18-28 X 40-55/*, usually narrowed below, often 

 attenuated at apex and sometimes considerably enlarged near the 

 septum in one or two places on one or both cells owing to the pres- 

 ence of hyaline papillae over the germ-pores, wall cinnamon-brown, 

 1-1.5/* thick, papillae 4.-711; pores 1 or 2 in each cell, apical or

Aecia hypophyllous, often in annul; 

 size, 6-16 mm. across, at first cylindric, 

 1-2 mm. high; peridium splitting rather early, 

 becoming deeply fimbriate; peridial cells usu- 

 ally seen in face view, lanceolate, 22-26 by 70-

 outer wall rather thin, about 1.5/1, inner and 

 side walls rather thick 5-7/*, coarsely rugose 

 with prominent ridge-like papillae; aeciospores 

 broadly ellipsoid, 25-27 by 28-33/*, wa U light 

 chestnut-brown, 1.5-2/* thick, finely verrucose. 



Telia caulicolous, with little or no hyper- 

 trophy, appearing on the smaller branches only, 

 hemispheric or slightly tongue-shaped, 1-1.5 

 mm. across, chestnut-brown; teliospores 2-
