It differs from Ombrophila clavus (A. & S.) Fr. in colour, the 

 receptacle is less convex, flatter and acuter at the margin, the 

 paraphyses are more obtuse, the smaller asci less attenuated at

Ascophores •3-'5 mm. wide, pallid, or ochraceous, waxy, sub- 

 pellucid, sessile, globose, punctiform, closed at first and when

 blue with iodine, 8- (rarely fewer) spored. Spores hyaline, ob- 

 long, more rarely clavate, 7-11 x i-5-2/x, continuous, finally

Von Hohnel in Annales Mycologici, xv, no. 5 (1917), 347-349,

 pothecium.
