HYPOXYLON AND ITS ALLIES. 
Hyp. semi-immersum. We find that the Rev. M. J. Berkeley re- 
garded Hypoxylon confluens as the species now answering to the 
name of Hypoxylon semi-immersum , and we doubt not, as far as 
British Botanists are concerned, we should have their sympathy 
in restoring the name of Hyp. confluens instead of H. semi-immer- 
sum. 
This communication has already extended to such a consider- 
able length that the remaining allied genera must stand over until 
next issue of this Journal.

The specimen in Cock’s fasciculus under Dictyosiphon fcenicu- 
laceus was probably obtained from the North of England or Scot- 
land, since there is no record of the plant as a southern species in 
this country. The transverse lines seen on the frond under a good 
lens distinguish it at sight from D. fceniculaceus , which it other- 
wise closely resembles in appearance. 
* The species marked with an asterisk will be published in forthcoming 
fasciculi. 
t Mrs. J. E. Gray’s collection of Marine Algse is now in the University 
Herbarium at Cambridge.
