Obs. — Under this name all the other British species of the 

 genus, with the exception of Fossombronia angidosa (Dicks.), were 

 formerly grouped. 



It belongs to that section of the arrangement of Herr Stephani, 

 with the laraelLc of the spore furcate, in which only another 

 British species is included, F. cristafa, Lindb., and in addition to 

 other characters, is distinguished from it by the fewer number 

 of crests, which are more laxly disposed. 



The var. oclirospora, so far as I am able to understand it, differs 

 but slightly from the type.
