360 FUNGUS-FLORA. 



Dasyscypha micacea. Mass. 



Scattered or gregarious, very minute, sessile, expanded, 

 extremely tender ; externally farinoso-tomentose, pale red or 

 dilute cinnamon ; disc the same colour ; asci cylindraceo- 

 clavate ; spores 8, fusiform, 3-5 x 1 p. ; paraphyses slenderly 

 filiform. 



Peziza micacea, Pers., Myc. Eur., p. 268. 



Lachnella micacea, Phil., Brit. Disc., p. 269. 



On dead stems of thistle. 



Ascophores about 200-300 p. broad. The hairs of the 

 exterior are short, slender, and deciduous. 



Unknown to me. A species respecting which there is a 

 considerable difference of opinion, and must ever be, as no 

 type specimen exists, and from the brief description given 

 by Persoon, I consider it is absolutely impossible to ascertain 

 exactly the species he had in view. The above description 

 is from Phillips, and describes the species considered by him 

 to be Persoon's fungus. 



Growing on bark, wood, or branches. 



Dasyscypha corticalis. Mass. 



Gregarious, sessile, but attached by a narrow base, globose 

 then hemispherical and expanded, up to $ mm. across; 

 excipulum thin, parenchymatous, irregularly polygonal, 

 becoming very narrow and radially elongated before passing 

 into the marginal fringe ; disc pale with slight red or 

 brown tinge ; externally densely pilose, hairs best developed 

 at the margin, where they are very numerous and of 

 irregular lengths, cylindrical or tapering to the end very 

 slightly, walls thin, septate, straight or slightly curved 

 sometimes, smooth, or minutely rough with fine particles of 

 lime, sometimes a large, irregular lump of lime occurs at the 

 apex, or binds 23 hairs together, pale brown at the base 

 becoming paler at the apex, or altogether almost colourless. 

 50-80 X 3-4 p. ; asci clavate, usually with an oblique pedicel 

 with a knob at the end, 8-spored ; spores irregularly biseriate, 

 narrowly fusiform, the widest part above the middle of the 

 spore, or the apex thickened and rounded, straight or usually 

 slightly bent, hyaline, 3-4-guttulate and at first continuous,
