TYPE HABITAT : On leaves Quercus Prinus, June 29, 1894 

 (Nuttall, discov. 1594, 542). 



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

 border, 2 to 3 mm. diameter. Perithecia epiphyllous, scat- 

 tered, erumpent, 90 to no ^ diameter. Sporules ovate or 

 oblong, hyaline, mostly a little curved, 5 to 6.5 x 2 to 2.5 /x.

that species the spots are larger, perithecia more prominent 



below, and sporules rather larger. Ph. marginal-is E. E. 



also has similar sporules, but the perithecia are hypophyllous.
