Drapamaldia glomerata Ag. Fumess Fells, Lancashire. 



On previous occasions of observing this beautiful plant, I have 

 been struck with the extremely long hyaline seta with which the 

 branches end, many times longer than the green portion of the 

 branch. This is not so figured in this species by either Hassall, 

 Kiitzing, or Cooke, though it is in other less common species of 

 the genus.
