II. Urediniospores lenticular or ellipsoid, 17-21 X 23-32 /x ; 

 wall light chestnut-brown, about 1.5 a* thick, rather finely echinu- 

 late, the pores 2, in the upper part. 



III. Teliospores clavate-oblong or clavate, 15-25X42-65^, 

 rounded above, usually narrowed below, somewhat constricted at 

 the septum; wall chestnut-brown, 1.5-2 /x thick, much thicker at 

 apex 7-13^; pedicel nearly colorless, about length of spore.

A well-defined species both from the point of view of struc- 

 tural characters and aecial connections. It is characterized in the 

 telial stage by the large well-developed sori and by the broad 

 robust spores which are so well rounded above. The usual len- 

 ticular shape of the urediniospores is also especially characteristic 

 of this species. No similar species has ever been reported from 

 Europe.
