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. 
Name—Truncus, a trunk of a tree; from the 
habitat.
