 fig. 304 ; Phil., Brit. Disc, p. 80 ; Sacc, Syll., viii. n. 334. 



Ascophore scattered, sessile, closed at first then expanding, 

 irregular and wavy, margin crenulate, umber or blackish- 

 brown, much contracted when dry, about 2 cm. across ; 

 hypothecium dense, excipulum formed of very large, 

 irregular cells; asci elongated, cylindrical, apex rounded, 

 8-spored ; spores irregularly 1-seriate. hyaline, smooth, 

 continuous, elliptical, ends obtuse, 18 X 10-11 /*; paraphyses 

 septate, slightly clavate, often with short lateral branchlets 

 near the apex, or furcate. 



On damp ground. 



Ascophores scarcely an inch broad: paraphyses thick, 

 septate, clavate at the tips, either furcate above, or with 

 short lateral branches or bud-like processes. (Phil.) 



Near to P. sepiatra, Cke., but the ascophore is rather 

 larger, the paraphyses more or less branched, and appears in 

 the autumn. 



Specimen from Phillips examined.
