 and minutely pulverulent; excipulum dingy orange, con- 

 sisting of parallel rows of septate hyphae that become 

 clavate, septate, and free from each other at the circum-

 with minute particles of lime; asci clavate or sometimes 

 cylindrical, and narrowed abruptly into a short pedicel, wall 

 thick, 8-spored ; spores irregularly 2-seriate, elliptic-oblong 

 or fusoid, straight or slightly curved, hyaline, often guttu- 

 late and with granular contents, smooth, for a long time 

 continuous, finally 3-septate, 1825 x 67 /j. ; paraphyses
