This is the moss mentioned in my ' Musci and Hepaticse of Tees- 

 dale ' (Annals, 1844) under no. 91, Hypnum multiflorum, Tayl., of 

 which, in deference to Dr. Taylor's opinion, I considered it a form. 

 It is however quite distinct from both that species and /. rufescens, 

 and is not Hke the latter confined to calcareous rocks.
