P. Quercus-prini E. & E., Proc. Phila. Acad., 1894, 356. 



Type habitat: On leaves Quercus Prinus, June 29, 1894 {jVutt-

Spots orbicular, rusty brown, definite, with a very narrow 

 border, 2 to 3 mm. diameter. Perithecia epiphyllous, scattered, 

 erumpent, 90 to no // diameter. Sporules ovate or oblong, hyaline,

 species the spots are larger, perithecia more prominent below, and 

 sporules rather larger. Ph. margijialis E. & E. also has similar 

 sporules, but the perithecia are hypophyllous.
