PEZIZA. 435 



margin generally remaining more or less incurved, often 

 irregular ; brittle, flesh thick at the base, becoming thin at 

 the margin; excipulum composed of interwoven, branched, 

 septate hyphae, mixed with concatenate vesicular cells ; the 

 latter project in irregular clusters and give the outside a 

 scurfy appearance ; disc often wrinkled, bright ochraceous, 

 externally paler ; asci cylindrical, dehiscing by an apical, 

 circular lid, 8 - spored ; spores elliptical, ends obtuse, 

 smooth, hyaline, continuous, 1— 2-guttulate, 21—25 x 10-12 /x ; 

 paraphyses slender, septate, apex slightly thickened, and 

 frequently with an indication of branching, hyaline. 



On the ground, frequently under beech-trees. 



Authentic specimen from Boudier examined. 



Peziza perlata. Fries, Syst. Myc, ii. p. 43 ; Karst., 

 Myc. Fenn., p. 39 ; Cooke, Mycogr., fig. 239. 



Cups large, shortly stipitate, at first subglobose, then 

 expanded, undulate, splitting at the margin ; externally 

 white, even ; hymenium wrinkled, pale cinnamon ; stem 

 stout, lacunose, white, flesh thick ; asci cylindraceo-clavate, 

 attenuated below the spores, truncate at the summit; 

 spores 8, elliptic, pale brown, smooth, 15-20 x 10-12 /x ; 

 paraphyses numerous, rather stout, septate, guttulate, 

 broadly clavate at the summit, brown.

On burnt charcoal beds. 



Cups 2| in. broad before expanding, 3| in., or even more 

 when expanded. Stem \ in. long, J in. broad ; flesh at base 

 of cup \ in. thick, near the margin 1 line thick. The spores 

 are pale brown, and homogeneous within. Karsten found 

 the spores in his specimens elliptic or fuso-elliptic, and 1-3- 

 guttulate, neither of which characters were present in my 

 specimens. Still I have no doubt they are correctly refer- 

 able to this species. 



The above is entirely from Phillips, who first recorded 

 the species as British, in Grevillea, vol. xviii., p. 82. As to 

 whether it is the species of Fries, I am unable to say, but 

 the description does not at all accord with the figure given 

 by Fries in Sveriges Svamper, t. 56, although this is quoted 

 by Phillips. It is remarkable that Phillips quotes Karsten 's
