DASYSCYPHA. 359 



On dead stems of umbellifers. 



Closely allied to D. Grevillei ; points of difference are noted 

 under the last named. 



Dasyscypha Grevillei. Mass. 



Ascophores scattered or gregarious, but more or less 

 narrowed at the base, about ^ mm. across, at first closed, 

 then hemispherical, every part varying from dingy ochra- 

 ceous to pale brown ; excipulum parenchymatous, the cells 

 very narrow, 3-4 p,, and much elongated radially ; externally 

 pilose, hairs most abundant and longest at the dentate 

 margin, the teeth consisting of clusters of slender, colourless 

 hairs, 30-40 x 3-4- /x,, apex clavate or pyriform, 6-8 p. thick, 

 rough with minute particles of lime ; asci cylindric-clavate, 

 apex narrowed, 8-spored ; spores irregularly biseriate, 

 cylindric-fusiform, straight or very slightly curved, hyaline 

 continuous, 2-3-guttulate, 6-9 x 2 p.; paraphyses filiform, 

 about 2 fji thick, apex not thickened, colourless.

Trichopeziza Grevillei, Sacc., Syll., viii. n. 1674. 



On dead stems of umbellifers. 



Very closely allied to, and also very closely resembling 

 D. Berkeleii ; differing in the much shorter and distinctly 

 clavate marginal hairs, and in the much smaller and narrower 

 cells of the excipulum near its margin. 



Dasyscypha prasina. Mass. 



Gregarious or crowded, sessile, at first hemispherical, then 

 expanded, becoming nearly plane, thin, waxy, soft, olive- 

 brown, clothed with bright, rufous, slender, flexuous hairs, 

 bright red below, colourless in the upper portion, margin 

 incurved, about ^ mm. across ; disc greyish bistre or green, 

 at length pale grey; asci cylindraceo-clavate ; spores 8, 

 fusiform straight or curved, 10-15 x 2-3 //,; paraphyses 

 filiform.
