0. Pycnia not seen. 



1. Aecia caulicolous, from a biennial mycelium, appearing on globoid or subreniform galls 

 (6-12 mm. across) of a reddish brown luster, cylindrical, 0.8-1.5 mm. high by 0.1-0.3 mm. 

 in diameter, ruptured tegumentary tissues raised ; peridium fragile, soon becoming lacerate, 

 often to base, spreading but not recurved ; peridial cells seen in both face and side views, 

 not hygroscopic, remaining straight when wet, narrowly obovate in face view, 18-25 by 

 50-75 M, Hnear-rhomboidal in side view, 15-18 m thick, the outer wall thin, about 1.5 ju, 

 smooth, the inner wall thicker, 3-5 \x, moderately rugose with closely set, linear, ridge-like 

 papillae of varying length ; aeciospores globoid or polygonal, 16-19 by 19-29 ju; wall dark 

 chestnut-brown, moderately thick, 2-2.5 ju, minutely verrucose, appearing smooth, the 

 pores 6-10, scattered. 



III. Telia following the aecia on the same galls, few, irregularly disposed, pulvinate, 

 low, roundish, 0.4-0.7 mm. across, dark cinnamon-brown, ruptured tegumentary tissues 

 somewhat evident ; teliospores 2-celled, ellipsoid, 18-25 by 34-50 ju, rounded or often some- 

 what narrowed both above and below, slightly constricted at the septum ; wall cinnamon- 

 brown, thin, about 1^, the pores 2 in each cell, near the septum ; pedicel cylindrical, uni- 

 form, 5-6 JU in diameter, rather long, three to four times length of spore.
