On dead stems of herbaceous plants. Not uncommon in the unex- 

 panded state, but only perfectly developed in alpine and subalpine 

 districts in consequence of their more constant moist atmosphere, as at 

 Appin where it is abundant. — It is curious, however, that even in the 

 imperfect plant, there is a sort of fructification, the contents of the asci 

 oozing out and forming a very fugacious globule.
