 septate, variable in length but reaching an extreme of 300-400 /x 

 and a diameter of 20-26 /x at the broadest point a little above 

 the base, contracted toward the point of attachment and often 

 forked at the base; asci cylindric or subcylindric above, gradually 

 tapering below into a stem-like base, reaching a length of 200- 

 250 M and a diameter of 25-30 /x; spores 1-seriate, at first smooth 

 and containing one large oil-drop, finally becoming sculptured, 

 reaching a diameter of 20-26 /x; spore-sculpturing consisring of
