Sori containing both urediniospores and teliospores, scattered, 

 minute, rarely confluent, erumpent; urediospores globose or ellipsoid, 

 cinnamon brown, with two or three germ-spores; teliospores oblong, 

 not clavate nor constricted at the septum, apex not thickened ; 15-24/x 

 by 29-41/A, brown, pedicel short and hyaline. 



On stems and leaves of Cordylanthes filifolia Nutt., collected by 

 E. Bethel at Cajon Pass, San Bernardino County. 



This species is more closely related to P. Adenostegiae Arth. than 

 to P. Anthirrhini Diet, and Holw. ; it differs from the latter in the 

 characters of the sori, and from both in the form and size of the telio- 

 spores. These differences are shown in the figures given below, which 

 represent the results of the measurement of forty mature spores of 

 each of the three species.
