the fibres prolonged above so as to make a marginal fringe of pale 

 yellow, roughish, straight hairs. Asci clavate-cylindrical, sessile, 

 curved 50-60 x 5-6//. Paraphyses filiform, hardly thickened above, 

 with a series of orange-colored, globose nuclei. Sporidia biseriate, 

 oblong, hyaline, obtuse, uniseptate but not constricted, 8-10 x 25-3//. 

 The outside of the ascomata is slightly hairy so that the specc. might 

 be referred to Solenopeziza, if that is really worthy of generic dis- 

 tinction.
