Amphigenous ; mycelium usually evanescent, but sometimes 

 persistent, and forming white orbicular spots or irregular patches 

 on the upper surface of the leaf; perithecia* usually somewhat gre- 

 garious, but varying from scattered to densely gregarious or even 

 caespitose, 58-1 20/^ in diameter, cells small, averaging 15 }i wide, 

 but varying from 10-20/^ wide ; appendages very variable, few^ or 

 numerous, usually long, often exceeding 9 times the diameter of 

 the perithecium, more or less straight, septate and colored dark 

 brown throughout, but sometimes short, tortuous, interwoven and 

 pale brown, sometimes even obsolete, very rarely flexuose and 

 more or less shining white throughout; ascus broadly elliptical
