Add the note: W. B. Cooke has used the name Pithya vulgaris 

 Fuckel instead of Pithya pithya (Pers.) Gill., the International 

 Congress having ruled out duplicate binomials. Since the name 

 used by the writer was also pre-Friesian perhaps it is preferable 

 to adopt the name used by Cooke, Pithya vulgaris Fuckel.
