" I am inclined to regard these as one species, com- 

 prising E. lachneum, squamulosum, and hepaticmn, Ach., 

 and Dickson's plant (and Hedwig's, I suppose,) as dis- 

 tinct." Mr. Borrer, in lit. 1850. 



All the above seemed identical in the section of the 

 thallus and form of the sporidia, though differing some- 

 what in the thallus, whose habit varied from the appressed 

 scaly state to that with the extremities of the lobes free.
