The head is about 2 lines broad, at first plane, 

 becoming convex, often slightly repand, umbilicate 

 beneath ; the stem, at first stuffed, becomes hollow, is 

 2 to 6 lines high, bluish-grey, with blackish squamules, 

 or smooth, darker towards the base ; the asci are very 

 long, cylindrical, numerous ; the sporidia very slenderly 

 filiform, divided by numerous septa, narrower towards 

 each extremity, 8 in each ascus; paraphyses numerous, 

 branched, septate, enlarged and brownish at the summits. 

 When removed from the water and exposed for a short 

 time to the air, the sporidia shoot out from the hyme- 

 nium with more or less violence, many of them remaining 

 attached by one extremity to the hymenium, waving to 

 and fro like floss silk, glistening in the light.
