 more or less elongated, sometimes curved, rough, wrinkled, shining- 

 black, erumpent ostiola. Asci narrow clavate-cylindrical, sessile, 8- 

 spored, 80-110x15-17 p. Sporidia filiform, slightly curved, with 

 several oil globules, faintly 6-7-septate, hyaline, 60-85 x 3-4 p.

 from Winter's Pilze.
