Didymodon aquaticus. 
“‘Didymodon aquaticus, Brid V mentioned in Spruce’s list, has 
reference to a moSs which I found near Malham, and could not 
then identify. Since then, I am satisfied that Dillenius’ moss, 
referred to by Bridel, is Racomitrium protensum ; and the Mal- 
ham moss I now regard as a very peculiar barren form of Tortula 
fallax, having the leaves much recurved and squarrose. It may, 
however, turn out to be a distinct species, whenever fruit shall 
be obtained. This form or species, I think, will be found, rather 
frequent in limestone districts, on banks” — W. Wilson, in litt. 
Nov. 7th, 1854. I have lately received fine specimens of the same 
moss from Ingleborough, (coll. J. Nowell,) and noticed it in the
