SECTION MERISMUS. 



4 mm. long. Spores globose, 3 mic., hyaline, smooth. When fresh 

 this is soft and would hardly be sought in Polystictus where it is 

 placed in our text books. It is quite a rare plant, known from Eng- 

 land, France, Germany. It is not a true Merismus, but is more close 

 to this section than any other in its appearance and habits.
