DASYSCYPHA. 365 



^— f mm. across ; disc greyish, externally brownish with an 

 olive tinge, minutely pilose, hairs, thin-walled, septate, 

 cylindrical, obtuse, greyish-olive at the base, upper portion 

 white, 40-50 X 4—5 /x, longest at the margin ; cortex 

 parenchymatous, cells more or less uniform in size, olive, 

 5-6 fx diameter ; asci cylindric-clavate, apex slightly nar- 

 rowed, 8-spored; spores hyaline, narrowly elliptic-fusiform 

 or often inclined to become clavate, straight or slightly 

 curved, 6-9 x 1'5-2/x; paraphyses slender, cylindrical, hya- 

 line, sometimes branched.

On dead stems of rose and bramble, also on dead wood ; 

 sometimes growing along with a black mould. 



An examination of Berkeley's type specimens of Peziza 

 dematiicola and P. escharodes shows that the two supposed 

 species are identical in every respect. As to whether the 

 species described by Phillips as Lachnella escharodes — Brit. 

 Disc, p. 262 — is identical with the species of Berkeley, I am 

 not certain ; " spores, 8x3/i; vertically striate or rugose," 

 are characters not apparent in the type specimen. 



Dasyseypha scrupulosa. Mass. 



Gregarious, sessile, subcylindrical, at first closed, then 

 open, the margin erect, thin, J mm. across; externally mi- 

 nutely pubescent, hairs delicate, thin-walled, cylindrical, 

 obtuse, rather closely septate, breaking-up at the septa when 

 placed in water and slightly moved, 30-40 X 3-4 //, ; whitish 

 at the edge, pale dingy yellow, tinged greyish-olive, or 

 greyish below; cortical cells, 4-5 /x diameter; asci clavate, 

 8-spored, small; spores irregularly 2-seriate, hyaline, con- 

 tinuous, linear- fusiform, 5-8 x 1*5 /x ; paraphyses very 

 slender, cylindrical.
