On dead bark of trees, poplar, &c 



Specimens in Kunze, Fung. Sel. Exs., n. 562, and Phil.,. 

 Elv. Brit., n. 112, examined. 



Distinguished from closely allied species by the large 

 fusiform spores having the widest part above the middle, 

 and by the slender, pale or colourless hairs, also by habitat. 



Dasyseypha barbata. Mass. 



Gregarious, sessile, depresso-globose and closed at first, 

 finally nearly plane but slightly marginate, firm, 1—1 • 5 mm. 

 across ; disc pallid, externally brownish, tomentose, hairs 

 best developed at the margin, thin-walled, septate, smooth, 

 cj'lindrical, obtuse or slightly swollen at the apex, rusty- 

 brown, 150-250x4-5 /jt,; cortex parenchymatous, cells 

 irregularly polygonal, 5-7 /x, diameter ; asci cylindric-clavate, 

 8-spored; spores irregularly 1-seriate, or 2-seriate upwards, 

 narrowly clavate, ends blunt, 2-guttulate, at length 1-septate, 

 9-12 X 2-2 • 5 ju, ; paraphyses cylindrical, hj'aline, 3-4 thick, 

 rather pointed and usually rough at the tips, longer than the 

 asci.

On dead stems of honeysuckle. Clematis, &c. 



Eeadily distinguished among the brown species by the 

 stout, cylindrical paraphyses, which are longer than the 

 asci. 



Specimens examined in Fries' Scler. Suec, n. 333, and 

 Eehm's Ascom., n. 16. 



Dasyseypha papillaris. Mass. 

 Gregarious or scattered, sessile, depresso-globose and closed 

 at first, then becoming plane, slightly narrowed towards the 

 base, contracted when dry, whitish or pale straw-colour, 

 externally pilose, margin very minutely denticulate, due to- 

 the presence of slender, almost cylindrical, straight or slightly
