This species is well distinguished by its finely rugose perithecial 

 wall, the granulosity forming transverse lines which are hardly visible 

 as the mature perithecium becomes nearly opaque. The apex usually 

 appears flat and hyaline with a slight elevation symmetrically placed 

 on either side, giving the eft'ect of a shallow cup. This form is not 

 always apparent, however, probably owing to a slight turn of the 

 perithecium. The brown suffusion of different individuals \aries 

 considerably and the receptacle may be either translucent or opaque.

Male mdividual more or less uni^formly tinged with yellowish brown, 

 erect. Receptacle three-celled, the cells somewhat obliquely super- 

 posed, the basal longer. Appendage erect, consisting of four cells, 

 the three lower subequal, the subbasal becoming rich deep brown; 

 the terminal one somewhat longer, slightly tapering. Antheridia 

 one or two, relatively large and long, the stalk well developed, the 

 slender long necks bent slightly inward, and reaching far above 

 the tip of the appendage. Receptacle 50 X 17 ^t. Appendage 

 50-60 X 7 ju. Antheridia 85 X 14 m, the necks 42 X 3 m- Total

Female individual tinged with yellowish brown, the perithecium 

 becoming rich dark brown. Receptacle consisting of four cells; the 

 two middle ones flattened and obliquely superposed. Primary ap- 

 pendage consisting of five or six cells, the basal slightly longer aiid 

 broader, the subbasal small and distinguished by constrictions and 

 dark septa. Secondary appendage consisting of six or more cells, 

 somewhat longer, extending a short distance above the stalk-portion 

 of the perithecium. Perithecium long and slender, erect, blackish 

 brown; the stalk portion pale, and distinctly indicated; the distal 

 portion curved inward; the short hyaline, slightly oblique apex turned 

 outward. Perithecia 250 X 30 ijl. Receptacle 64 X 22 n. Primary
